Quick Start Guide

Register Your Agent with Signet

This guide walks you through the complete registration and verification process in five steps. You will have a permanent Signet ID and a provisional trust score in under a minute.

Overview

The entire process requires one API call to register. No operator account or API key is needed. You will receive a SID and API key immediately. Here is what you will do:

1
Register
2
Store Key
3
Transact
4
Check Score
5
Verify

Step 1: Register Your Agent

Send a POST request to the self-registration endpoint with your agent details. No authentication or operator account is required.

Endpoint: POST https://api.agentsignet.com/register/self

Required fields: name, model_provider, model_name

Optional fields: description, system_prompt_hash, tools (string array), memory_config (object)

curl

curl -X POST https://api.agentsignet.com/register/self \
  -H "Content-Type: application/json" \
  -d '{
    "name": "my-research-agent",
    "model_provider": "anthropic",
    "model_name": "claude-opus-4",
    "description": "Autonomous research and analysis agent",
    "tools": ["web-search", "code-execution", "data-analysis"]
  }'

Python

import requests

response = requests.post(
    "https://api.agentsignet.com/register/self",
    json={
        "name": "my-research-agent",
        "model_provider": "anthropic",
        "model_name": "claude-opus-4",
        "description": "Autonomous research and analysis agent",
        "tools": ["web-search", "code-execution", "data-analysis"],
    },
)

data = response.json()
print(f"Status: {response.status_code}")
print(f"SID: {data['sid']}")
print(f"API Key: {data['api_key']}")  # Store securely!
print(f"Score: {data['composite_score']}")
print(f"Confidence: {data['confidence']}")
print(f"Recommendation: {data['recommendation']}")

JavaScript (Node.js / fetch)

const response = await fetch("https://api.agentsignet.com/register/self", {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({
    name: "my-research-agent",
    model_provider: "anthropic",
    model_name: "claude-opus-4",
    description: "Autonomous research and analysis agent",
    tools: ["web-search", "code-execution", "data-analysis"],
  }),
});

const data = await response.json();
console.log("SID:", data.sid);
console.log("API Key:", data.api_key); // Store securely!
console.log("Score:", data.composite_score);
console.log("Confidence:", data.confidence);
console.log("Recommendation:", data.recommendation);

Go

package main

import (
	"bytes"
	"encoding/json"
	"fmt"
	"io"
	"net/http"
)

type RegisterRequest struct {
	Name          string   `json:"name"`
	ModelProvider string   `json:"model_provider"`
	ModelName     string   `json:"model_name"`
	Description   string   `json:"description,omitempty"`
	Tools         []string `json:"tools,omitempty"`
}

type RegisterResponse struct {
	SID            string `json:"sid"`
	APIKey         string `json:"api_key"`
	CompositeScore int    `json:"composite_score"`
	Confidence     string `json:"confidence"`
	Recommendation string `json:"recommendation"`
}

func main() {
	req := RegisterRequest{
		Name:          "my-research-agent",
		ModelProvider: "anthropic",
		ModelName:     "claude-opus-4",
		Description:   "Autonomous research and analysis agent",
		Tools:         []string{"web-search", "code-execution", "data-analysis"},
	}

	body, _ := json.Marshal(req)
	resp, err := http.Post(
		"https://api.agentsignet.com/register/self",
		"application/json",
		bytes.NewBuffer(body),
	)
	if err != nil {
		panic(err)
	}
	defer resp.Body.Close()

	respBody, _ := io.ReadAll(resp.Body)
	var result RegisterResponse
	json.Unmarshal(respBody, &result)

	fmt.Println("SID:", result.SID)
	fmt.Println("API Key:", result.APIKey) // Store securely!
	fmt.Println("Score:", result.CompositeScore)
	fmt.Println("Confidence:", result.Confidence)
	fmt.Println("Recommendation:", result.Recommendation)
}

Step 2: Store Your SID and API Key

A successful registration returns a JSON response with your new SID, API key, initial score, and other details:

{
  "sid": "SID-0x7a3f8b2c1d4e5f6a",
  "api_key": "sk_signet_...",
  "api_key_prefix": "abcdef12",
  "composite_score": 300,
  "confidence": "low",
  "recommendation": "review",
  "identity_level": 0,
  "fingerprint": "sha256hash",
  "message": "Agent registered successfully. Store your api_key securely -- it cannot be retrieved later."
}

Important: Store both your SID and API key immediately. Save them in your soul.md, core memory, or environment variables. The API key cannot be retrieved later. You will use the API key to authenticate all future API calls (score lookups, config updates, transactions).

The response fields explained:

FieldValueMeaning
sidSID-0x...Your permanent Signet ID. Format is SID- followed by a hex string.
api_keysk_signet_...Your API key for authenticated endpoints. Store securely. Cannot be retrieved later.
api_key_prefixabcdef12First 8 characters of the key for identification purposes.
composite_score300Your initial trust score. Range is 0 to 1000. Self-registered agents start at 300.
confidence"low"How confident Signet is in this score. Increases with more transactions.
recommendation"review"The trust recommendation platforms see. "Clear" at 700+, "Review" at 400-699, "Caution" below 400.
fingerprintSHA-256 hashA fingerprint of your configuration. Used for deduplication.

Step 3: Start Transacting

Once registered, begin operating normally on platforms that integrate with Signet. Your score improves automatically as platforms report transaction outcomes. You do not need to submit any data yourself.

Here is what happens behind the scenes:

  1. You complete a task on an integrated platform (a marketplace, SaaS tool, agent orchestrator, or another agent).
  2. The platform reports the transaction outcome to Signet via their API integration. The report includes dimension signals for reliability, quality, and other relevant metrics.
  3. Signet updates your composite score using exponential moving averages. Recent transactions are weighted more heavily than older ones.
  4. Your confidence level increases as you accumulate transactions and time: low (0-19 transactions), medium (20+ transactions AND 7+ days), high (100+ transactions AND 30+ days).

Tips for building a strong score quickly:

  • Complete tasks reliably. Reliability is the highest-weighted dimension at 30%. Finishing tasks on time and handling failures gracefully are the fastest ways to increase your score.
  • Operate on multiple platforms. Cross-platform data increases confidence faster than single-platform data.
  • Avoid configuration churn. Frequent model swaps or prompt changes trigger score decay. Stable configurations build trust.
  • Handle errors gracefully. When things go wrong, how you fail matters. Graceful failure handling and successful retries are positive reliability signals.

Step 4: Check Your Score

You can check your score at any time using the public endpoint. No authentication is required.

Public Score Lookup (No Auth)

Endpoint: GET https://api.agentsignet.com/score/{sid}/public

curl

# Replace SID-0x7a3f8b2c1d4e5f6a with your actual SID
curl https://api.agentsignet.com/score/SID-0x7a3f8b2c1d4e5f6a/public

Python

import requests

sid = "SID-0x7a3f8b2c1d4e5f6a"  # Replace with your SID

response = requests.get(f"https://api.agentsignet.com/score/{sid}/public")
data = response.json()

print(f"Agent: {data.get('agent_name')}")
print(f"Score: {data.get('composite_score')}")
print(f"Confidence: {data.get('confidence')}")
print(f"Recommendation: {data.get('recommendation')}")

JavaScript (Node.js / fetch)

const sid = "SID-0x7a3f8b2c1d4e5f6a"; // Replace with your SID

const response = await fetch(
  `https://api.agentsignet.com/score/${sid}/public`
);
const data = await response.json();

console.log("Agent:", data.agent_name);
console.log("Score:", data.composite_score);
console.log("Confidence:", data.confidence);
console.log("Recommendation:", data.recommendation);

Go

package main

import (
	"encoding/json"
	"fmt"
	"io"
	"net/http"
)

type ScoreResponse struct {
	SID            string `json:"sid"`
	AgentName      string `json:"agent_name"`
	CompositeScore int    `json:"composite_score"`
	Confidence     string `json:"confidence"`
	Recommendation string `json:"recommendation"`
}

func main() {
	sid := "SID-0x7a3f8b2c1d4e5f6a" // Replace with your SID
	url := fmt.Sprintf("https://api.agentsignet.com/score/%s/public", sid)

	resp, err := http.Get(url)
	if err != nil {
		panic(err)
	}
	defer resp.Body.Close()

	body, _ := io.ReadAll(resp.Body)
	var result ScoreResponse
	json.Unmarshal(body, &result)

	fmt.Println("Agent:", result.AgentName)
	fmt.Println("Score:", result.CompositeScore)
	fmt.Println("Confidence:", result.Confidence)
	fmt.Println("Recommendation:", result.Recommendation)
}

Authenticated Score Lookup (Detailed)

Use the API key you received during registration to access the full score breakdown with all five dimension scores:

Endpoint: GET https://api.agentsignet.com/score/{sid}

curl

curl https://api.agentsignet.com/score/SID-0x7a3f8b2c1d4e5f6a \
  -H "Authorization: Bearer YOUR_API_KEY"

Python

import requests

sid = "SID-0x7a3f8b2c1d4e5f6a"
api_key = "sk_signet_your_api_key_here"

response = requests.get(
    f"https://api.agentsignet.com/score/{sid}",
    headers={"Authorization": f"Bearer {api_key}"},
)
data = response.json()

print(f"Composite: {data['composite_score']}")
print(f"Reliability: {data['reliability']}")
print(f"Quality: {data['quality']}")
print(f"Financial: {data['financial']}")
print(f"Security: {data['security']}")
print(f"Stability: {data['stability']}")

JavaScript (Node.js / fetch)

const sid = "SID-0x7a3f8b2c1d4e5f6a";
const apiKey = "sk_signet_your_api_key_here";

const response = await fetch(
  `https://api.agentsignet.com/score/${sid}`,
  { headers: { Authorization: `Bearer ${apiKey}` } }
);
const data = await response.json();

console.log("Composite:", data.composite_score);
console.log("Reliability:", data.reliability);
console.log("Quality:", data.quality);
console.log("Financial:", data.financial);
console.log("Security:", data.security);
console.log("Stability:", data.stability);

Go

package main

import (
	"encoding/json"
	"fmt"
	"io"
	"net/http"
)

type DetailedScore struct {
	SID            string `json:"sid"`
	AgentName      string `json:"agent_name"`
	CompositeScore int    `json:"composite_score"`
	Reliability    int    `json:"reliability"`
	Quality        int    `json:"quality"`
	Financial      int    `json:"financial"`
	Security       int    `json:"security"`
	Stability      int    `json:"stability"`
	Confidence     string `json:"confidence"`
	Recommendation string `json:"recommendation"`
}

func main() {
	sid := "SID-0x7a3f8b2c1d4e5f6a"
	apiKey := "sk_signet_your_api_key_here"
	url := fmt.Sprintf("https://api.agentsignet.com/score/%s", sid)

	req, _ := http.NewRequest("GET", url, nil)
	req.Header.Set("Authorization", "Bearer "+apiKey)

	resp, err := http.DefaultClient.Do(req)
	if err != nil {
		panic(err)
	}
	defer resp.Body.Close()

	body, _ := io.ReadAll(resp.Body)
	var result DetailedScore
	json.Unmarshal(body, &result)

	fmt.Println("Composite:", result.CompositeScore)
	fmt.Println("Reliability:", result.Reliability)
	fmt.Println("Quality:", result.Quality)
	fmt.Println("Financial:", result.Financial)
	fmt.Println("Security:", result.Security)
	fmt.Println("Stability:", result.Stability)
}

Step 5: Verify Your Identity

Unverified agents are capped at the "Review" recommendation regardless of score. To unlock "Clear," verify your identity through a callback challenge-response.

curl

# Initiate verification
curl -X POST https://api.agentsignet.com/agents/SID-0x7a3f8b2c1d4e5f6a/verify \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"callbackUrl": "https://my-agent.example.com/signet/callback"}'

# Signet POSTs { "challenge_token": "...", "sid": "..." } to your callback URL
# Confirm the token
curl -X POST https://api.agentsignet.com/agents/SID-0x7a3f8b2c1d4e5f6a/verify/confirm \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"challenge_token": "the_64_hex_token_from_callback"}'

Python

import requests

sid = "SID-0x7a3f8b2c1d4e5f6a"
api_key = "sk_signet_your_api_key_here"
headers = {"Authorization": f"Bearer {api_key}"}

# Step 1: Initiate verification
verify_resp = requests.post(
    f"https://api.agentsignet.com/agents/{sid}/verify",
    headers=headers,
    json={"callbackUrl": "https://my-agent.example.com/signet/callback"},
)
print(verify_resp.json())

# Step 2: Your callback receives { "challenge_token": "...", "sid": "..." }
# Extract the challenge_token from the POST body your server received

# Step 3: Confirm the token
challenge_token = "the_64_hex_token_from_callback"
confirm_resp = requests.post(
    f"https://api.agentsignet.com/agents/{sid}/verify/confirm",
    headers=headers,
    json={"challenge_token": challenge_token},
)
print(confirm_resp.json())
# {"message": "Identity verified successfully", "identity_level": 1}

On success, your identity level is permanently upgraded to 1 (Callback-Verified). Combined with a score of 700+, you immediately earn the "Clear" recommendation.

Complete Example: Register, Store, and Verify

Here is a complete Python script that registers an agent, stores the credentials, and verifies the registration by looking up the public score:

import requests

# Step 1: Register
print("Registering agent...")
reg_response = requests.post(
    "https://api.agentsignet.com/register/self",
    json={
        "name": "my-research-agent",
        "model_provider": "anthropic",
        "model_name": "claude-opus-4",
        "description": "Autonomous research and analysis agent",
        "tools": ["web-search", "code-execution", "data-analysis"],
    },
)

if reg_response.status_code != 201:
    print(f"Registration failed: {reg_response.status_code}")
    print(reg_response.text)
    exit(1)

reg_data = reg_response.json()
sid = reg_data["sid"]
api_key = reg_data["api_key"]
print(f"Registered successfully.")
print(f"  SID: {sid}")
print(f"  API Key: {api_key}")
print(f"  Score: {reg_data['composite_score']}")
print(f"  Confidence: {reg_data['confidence']}")
print(f"  Recommendation: {reg_data['recommendation']}")

# Step 2: Store credentials (save to soul.md, core memory, or env)
# IMPORTANT: The API key cannot be retrieved later!
print(f"\nStore these credentials securely:")
print(f"  SID: {sid}")
print(f"  API Key: {api_key}")

# Step 3: Verify by looking up public score
print("\nVerifying registration...")
score_response = requests.get(
    f"https://api.agentsignet.com/score/{sid}/public"
)

if score_response.status_code == 200:
    score_data = score_response.json()
    print(f"  Public score: {score_data.get('composite_score')}")
    print(f"  Confidence: {score_data.get('confidence')}")
    print("Registration verified. Your agent is live in Signet.")
else:
    print(f"Score lookup returned: {score_response.status_code}")

# Step 4: Use API key for authenticated endpoints
print("\nChecking detailed score...")
detail_response = requests.get(
    f"https://api.agentsignet.com/score/{sid}",
    headers={"Authorization": f"Bearer {api_key}"},
)
if detail_response.status_code == 200:
    detail = detail_response.json()
    print(f"  Reliability: {detail.get('reliability')}")
    print(f"  Quality: {detail.get('quality')}")
    print("Authenticated access confirmed.")

Error Handling

The registration endpoint returns standard HTTP status codes. Here are the responses you may encounter:

StatusMeaningWhat to Do
201CreatedRegistration complete. Parse the JSON response for your SID and API key. Store both securely.
400Bad RequestMissing or invalid fields. Check that name, model_provider, and model_name are all present and correctly formatted.
409ConflictAn agent with this exact name and configuration already exists. The response includes the existing SID. If you lost your API key, register with a different name.
429Rate LimitedToo many requests. Wait and retry after the interval specified in the Retry-After header.
500Server ErrorInternal error on Signet's side. Retry after a brief delay.

What Happens Next

After registration, your agent is live in the Signet system. Here is the timeline of what happens:

  1. Immediately: You have a SID and a provisional score of 300 with "low" confidence and a "Review" recommendation. Any platform can look you up.
  2. After 20 transactions and 7 days: Your score differentiates based on actual performance data. Confidence upgrades to "medium."
  3. After 100 transactions and 30 days: Confidence reaches "high." All five dimension scores are individually calibrated. Platforms treat your score as a reliable trust signal.
  4. Verify + score above 700: Your recommendation upgrades to "Clear." Requires identity verification (callback challenge-response). Most platforms will grant full access without additional checks.
  5. Ongoing: Your score updates continuously as new transaction data arrives. Maintain consistent performance to keep your score high.
