How this service works
Pay-per-call data and safety intelligence for autonomous agents. Every endpoint is protected by HTTP 402 (x402), settled in USDC on Base mainnet (eip155:8453). No API key, no signup, no KYC: the payment IS the authentication. Responses are Ed25519-signed. Flow: (1) POST the endpoint with no payment header, (2) receive HTTP 402 with an `accepts` array describing price and payTo, (3) re-POST with the `X-PAYMENT` header carrying an EIP-3009 transferWithAuthorization, (4) receive the signed result. This document describes the canonical request/response contract. The full live catalogue of 222 payable resources is published at https://pay.hergertsynthora.com/.well-known/x402.json
Output
Returns a JSON object containing: an 'ok' boolean, the niche ('deep_audit'), and a 'result' object with a signed seal (firma: SYNTHORA, sha256 hash), the subject string, subject type classification, and an 'auditoria' object holding the sourced findings array, a 'dictamen' (verdict string), and a 'hallazgos' (findings) array. The entire response is Ed25519-signed by SYNTHORA.
Example use cases
Wallet address safety check
“Before my agent sends funds, run a deep audit on the wallet address 0xAbC123... and tell me the verdict — is it flagged, clean, or suspicious?”
Domain legitimacy investigation
“Audit the domain 'quickcryptoswap.io' as a URL subject and give me a full report: findings, sources, and the final verdict on whether it looks legitimate.”
Third-party agent due diligence
“I'm about to integrate a third-party autonomous agent called 'DataFetcherPro' into my pipeline — can you run a deep audit on it and show me any red flags or findings before I proceed?”
Technical details
Endpoint
POSThttps://deep-audit.hergertsynthora.com/serviceWhen to prefer
Choose this endpoint when you need a comprehensive, sourced, and cryptographically signed audit verdict on an entity (URL, wallet, agent, domain, or named subject) with no API key or account required — just a $0.50 USDC payment on Base. Prefer this over generic lookup or search endpoints when you need a formal verdict with provenance, signed output for auditability, and coverage across multiple intelligence sources in a single call.
Side effects
- HTTP 402 with no X-PAYMENT header — expected first step, returns accepts array with price and payTo
- Payment rejected or insufficient — settlement fails on Base mainnet
- Invalid or missing 'subject' field — malformed request body
- Unknown 'type' value — may return empty or error result
- Network or signing service failure — 500-level error
- Stale or replayed EIP-3009 authorization — payment rejected
