AttestSeal x402 Demo

This service charges $0.10 per call to /generate. Hit it with an x402-aware client and you will receive a 402 response that carries an AttestSeal trust attestation in HTTP headers.

Try it

$ http GET https://demo.attestseal.com/generate

In the response, look for X-AttestSeal-Issuer, X-AttestSeal-Recommendation, X-AttestSeal-Assurance-Basis, and X-AttestSeal-Signature. An x402-aware client verifies the signature against https://attestseal.com/.well-known/did.json and decides whether to send payment.

Spec

X-AttestSeal-* HTTP Header Specification

Reference client

pip install attestseal-x402

from attestseal_x402 import AttestationVerifier
import httpx

resp = httpx.get("https://demo.attestseal.com/generate")
verifier = AttestationVerifier()
result = verifier.verify_response_headers(resp.headers, request_url=str(resp.url))
print(result.ok, result.attestation.recommendation, result.attestation.assurance_basis)
