Witness Holoweave Signature Acceptance Check
x402
Witness Holoweave Signature Acceptance Check is a paid API for AI agents from witness.holoweave.org, paid per call via x402, $0.01/call, status down (last checked 2026-09-15).
Checks whether a signed HTTP request would be accepted by major bot-auth verifiers (Cloudflare, AWS WAF, Akamai, Vercel) according to the draft-meunier-web-bot-auth-architecture spec

How this service works
Web bot auth debugging for AI agents, priced per check at $0.01. RFC 7638 keyid thumbprint verification, RFC 9421 Ed25519 signature verification, and per-verifier acceptance rules. Signed attestations, published fixtures, sources with dates.
Output
A per-verifier acceptance verdict indicating whether the signed request would pass bot-auth checks on each requested platform (Cloudflare, AWS WAF, Akamai, Vercel). Cloudflare provides form-level rule detail; others return 'unknown' if rules aren't published. Includes overall compliance status against the draft-meunier-web-bot-auth-architecture spec.
Example use cases
Pre-flight Cloudflare bot auth check
“Before I send my signed agent request to this Cloudflare-protected API, can you check if my Signature-Input and Signature headers would actually be accepted? My JWKS is at https://mybot.example.com/.well-known/jwks.json and I want to validate against Cloudflare.”
Multi-verifier acceptance audit
“I'm deploying my agent to talk to APIs behind different WAFs — can you check my signed request headers against Cloudflare, AWS WAF, and Akamai to see which ones would accept or reject my bot-auth signature?”
Debug failing bot-auth signature
“My agent keeps getting blocked when hitting Vercel-protected endpoints. Can you judge whether my Signature-Input, Signature, and Signature-Agent headers are correctly formed for the draft-meunier-web-bot-auth-architecture spec?”
Technical details
Endpoint
POSThttps://witness.holoweave.org/v1/signature-acceptanceWhen to prefer
Use this endpoint when you need to pre-flight check whether an agent's signed HTTP request will be accepted by specific deployed WAF/bot-auth verifiers before actually sending it. It is purpose-built for the draft-meunier-web-bot-auth-architecture spec and tests against real verifier rule sets (especially Cloudflare). Prefer this over generic signature validators when you specifically need per-verifier acceptance decisions, not just cryptographic correctness — for that, use the sibling RFC 9421 signature verification endpoint instead.
Side effects
- Missing required headers (Signature-Input, Signature) returns validation error
- Invalid JWKS URI or unreachable key directory causes key lookup failure
- Unsupported verifier name returns error or unknown verdict
- Malformed request_sample object causes schema validation rejection
- Network issues reaching verifier endpoints may return partial results
