API Endpoint

POST https://api.stackgoai.com/api/v1/extract-contact

Send JSON with the Content-Type: application/json header. The body must contain exactly one field: url.

{
  "url": "https://example.com/about"
}
curl -X POST 'https://api.stackgoai.com/api/v1/extract-contact'   -H 'Content-Type: application/json'   -d '{"url":"https://example.com/about"}'

Use a complete public http:// or https:// business website URL. Invalid request shapes return HTTP 400 before payment. A valid but unpaid request returns HTTP 402.

Payment happens automatically via x402 v2: $0.01 USDC per request on Base mainnet.
