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
A JSON object containing: a boolean ok field, a niche identifier ('osint_flash'), a result object with a 'tema' field (the subject), a 'brief' object containing an array of brief bullet points, a list of sources ('fuentes'), and a headline ('titular'), plus a 'sello' object with a SYNTHORA signature label and a SHA256 hash for cryptographic verification. Responses are Ed25519-signed.
Example use cases
Rapid due diligence on a counterparty
“Run an OSINT flash brief on 'Nexus Capital Partners' covering the past 14 days — give me the headline and a bullet-point summary with sources so I can assess any red flags before our meeting.”
Monitoring a competitor's recent activity
“Get me a signed OSINT intelligence digest on 'OpenAI' for the last 30 days, including sources and the brief summary, so I can track what they've been up to.”
Background check on a public figure
“I need a quick OSINT flash report on 'Elon Musk' from the last 3 days — headline, brief, and sources please, and make sure it's signed so I can verify authenticity.”
Technical details
Endpoint
POSThttps://osint-flash.hergertsynthora.com/serviceWhen to prefer
Choose this endpoint when you need a fast, cryptographically signed OSINT intelligence brief on any topic without requiring an API key or account signup — payment in USDC on Base mainnet is the sole authentication mechanism. Prefer this over traditional OSINT APIs when operating in a trustless or autonomous agent context where per-call micropayments are preferred over subscription credentials, and when response authenticity verification via Ed25519 signature and SHA256 hash is required.
Side effects
- HTTP 402 returned if no payment header is provided — caller must re-POST with X-PAYMENT header carrying valid EIP-3009 transferWithAuthorization
- Insufficient USDC balance on Base mainnet causes payment failure and no result returned
- Malformed topic string or missing required fields may result in error response
- Topic with no available open-source data may return empty brief and sources arrays
- Payment authorization expired or replayed may be rejected by the x402 facilitator
