Counterparty checks for agents.

Give a company name, a registry number, a VAT number, an LEI or a website. Get the legal entity from the official register, LEI and parents, VAT, a sanctions screen and the domain's records, each field with its source and time, the answer signed. Stablecoins, no account.

1. Preview

Ask the free preview whether the request can be answered. It shows matching companies and the price.

2. Pay

POST the request, sign the quote with x402 or MPP and send it again.

3. Read

One JSON record with every source, source link and retrieval time.

4. Verify

Check the signature offline. A lookup that finds nothing is not charged.

Good to know

• Sources: Official registers, sanctions lists and open data
• Payment: Stablecoins, x402 and MPP, no account
• Trust: Every answer is signed; verify with the published key
• Run by: shveik.dev
• Compared with: Business-data platforms sell accounts and bulk plans; agosint quotes each check for stablecoin payment and returns official register data with its source, signed.

Authentication/payment

No API key or account is required. The unpaid request returns HTTP 402 with a quote: x402 uses PAYMENT-REQUIRED and a paid retry with PAYMENT-SIGNATURE; MPP uses WWW-Authenticate: Payment and a paid retry with Authorization: Payment. Review and sign the quote, then retry the same request. See the deprecation policy.

Pricing

Current endpoint prices and limits are generated at https://agosint.shveik.dev/pricing.md. Each quote is returned before payment.

OpenAPI

OpenAPI 3.1

MCP

Remote MCP is available at https://agosint.shveik.dev/mcp, with tools corresponding to the enabled endpoints.

Rate limits

Free documents are limited to 120 requests per IP per minute. Paid API routes have no general request quota; endpoint-specific limits are documented with each route.

Limits and reliability

No uptime SLA; service and upstream availability are best-effort. Free GET documents, including /docs, /agents.md, /llms.txt, /openapi.json, /pricing and /pricing.md, are limited to 120 requests per client IP per minute and return RateLimit headers; HTTP 429 includes Retry-After. Paid-route timeouts and any route-specific in-flight limits are described in the product docs. GET /health is a liveness check on agdata, agproxy and agvps; agmail and agpay use GET /healthz. HTTP 402 means payment is required, 429 means a limit was reached, 502 means delivery failed, and 503 means the service cannot accept work; follow Retry-After when present. Review the quote before paying. An unpaid request returns a quote before payment; work starts after settlement. A request refused before settlement is not charged; product-specific refund rules apply.

Capabilities
