Witnessory: Bulk Post-Quantum Cryptography Readiness Check

x402

Witnessory: Bulk Post-Quantum Cryptography Readiness Check is a paid API for AI agents from api.witnessory.org, paid per call via x402, $0.1/call, status unknown (last checked 2026-10-31).

Checks multiple domains at once for post-quantum TLS and SSH cryptography support, returning signed, recomputable readiness records for each.

How this service works

58.4% of the top 10,000 sites negotiate post-quantum TLS; 52.3% of SSH servers offer post-quantum key exchange. As of 2026-10-27, from 4 probes; signed readings, recomputable.

Output

A JSON object keyed by domain name, each containing a readiness record (level, domain, checked UTC timestamp), a human-readable summary of the post-quantum TLS/SSH status, and dual cryptographic signatures (Ed25519 and MLDSA65) attesting to the reading's authenticity and recomputability.

Example use cases

Audit company domains for quantum readiness

“Check post-quantum TLS readiness for all our main domains — company.com, api.company.com, and blog.company.com — and give me signed proof of the results.”

Security report on top competitor sites

“I'm writing a security report — can you check whether stripe.com, paypal.com, and square.com have post-quantum TLS enabled and what key exchange algorithms they're using?”

Verify infrastructure before quantum migration

“Before we finalize our quantum-safe migration plan, check example.org and example.net to confirm their current post-quantum cryptography readiness levels with cryptographically signed attestations.”

When to prefer

Use this endpoint when you need to check post-quantum cryptography readiness for multiple domains in a single call and require cryptographically signed, recomputable attestations. Prefer it over single-domain checks when auditing a portfolio of domains or generating compliance reports. It is especially valuable when you need tamper-evident proof of a domain's post-quantum TLS or SSH status, backed by dual signatures (Ed25519 + MLDSA65).

Side effects

Domain unreachable or DNS resolution failure — record may be absent or contain error state
Invalid input body format — 400 error if required fields are missing or bodyType mismatch
Payment failure — x402 payment not processed, returns 402 Payment Required
Rate limiting or quota exceeded — too many domains in a single batch
Stale or cached probe data — readings may reflect probe timestamp rather than real-time state
