NervePay Identity — Agent Instructions

You are an AI agent with a NervePay identity. This skill lets you prove WHO you are using W3C DIDs and Ed25519 cryptographic signatures.

What This Skill Does

• Registers your identity: Creates a unique DID (Decentralized Identifier) for you
• Authenticates you: Signs requests with Ed25519 so API providers know it's really you
• Proves ownership: Cryptographic verification that you control your identity
• NO analytics tracking: This skill is identity-only. Use nervepay-analytics for tracking or nervepay for both.

Step 1: Download Helper Script

First, download the NervePay signing helper:

# Download signing script
curl -o nervepay-request.mjs https://nervepay.xyz/nervepay-request.mjs
chmod +x nervepay-request.mjs

This script handles Ed25519 signing for authenticated requests.

Step 2: Register Your Identity

If you don't have NERVEPAY_DID and NERVEPAY_PRIVATE_KEY env vars, register first:

curl -X POST https://api.nervepay.xyz/v1/agent-identity/register-pending \
  -H "Content-Type: application/json" \
  -d '{
    "name": "Your Agent Name",
    "description": "What you do"
  }'

Save these from the response:

• did → Set as NERVEPAY_DID
• private_key → Set as NERVEPAY_PRIVATE_KEY
• mnemonic → Backup for recovery (24 words)
• claim_url → Give to your human owner to claim you

You can start authenticating immediately. Human ownership (via claim_url) is optional but recommended for better trust scores.

Making Authenticated Requests

Use the helper script to sign and send authenticated requests:

# Test authentication
node ./nervepay-request.mjs GET /v1/agent-identity/whoami

# Check your capabilities
node ./nervepay-request.mjs GET /v1/agent-identity/capabilities

# Authenticated POST (example)
node ./nervepay-request.mjs POST /v1/some-endpoint '{"key":"value"}'

The script handles Ed25519 signing automatically. It reads NERVEPAY_DID, NERVEPAY_PRIVATE_KEY, and NERVEPAY_API_URL (default: https://api.nervepay.xyz) from environment.

What the Signature Proves

Required Headers (automatically added)

The helper script adds these automatically:

• Agent-DID: Your DID
• X-Agent-Signature: Base64-encoded Ed25519 signature
• X-Agent-Nonce: Unique nonce (UUID)
• X-Signature-Timestamp: ISO 8601 timestamp

Common Commands

Test authentication

node ./nervepay-request.mjs GET /v1/agent-identity/whoami

Returns your DID, name, reputation score, and confirms authentication works.

Check your capabilities

node ./nervepay-request.mjs GET /v1/agent-identity/capabilities

Shows your spending limits, allowed operations, and permissions.

Verify another agent

curl "https://api.nervepay.xyz/v1/agent-identity/verify/did:nervepay:agent:abc123xyz"

No auth required. Returns public profile, reputation, and transaction stats for any agent.

Poll claim status (check if human claimed you)

curl "https://api.nervepay.xyz/v1/agent-identity/register-pending/SESSION_ID/status"

Returns: pending, claimed, expired, or revoked.

Security Notes

• Private key: NEVER send to any server. Only send signatures.
• Nonces: Single-use. Generate new for each request (script handles this).
• Timestamps: Must be within 5 minutes of server time.
• Mnemonic: 24-word backup phrase. Store securely offline.

Need Analytics Too?

This skill is identity-only. To track API usage and build reputation:

• Use nervepay-analytics skill for analytics-only
• Use nervepay skill for both identity + analytics
