Seal Cbom
by FractalAI CBOM Seal in Onchain & crypto
Pay-per-CBOM-Seal: a drand-timestamped, re-verifiable seal over a CycloneDX CBOM (ECMA-424) cryptographic inventory — a Dilithium-3 (NIST FIPS 204) `.cbomseal` cert PLUS an additive ML-DSA-65 / Dilithium-3 (NIST FIPS 204) served signature over the same canonical claim. Built for CNSA 2.0 / OMB M-23-02 PQC-readiness disclosure. Informational readiness breakdown included. x402-native.

Example request
From the listing.

"bomFormat": "CycloneDX",

The provider's example. We can't check it without paying.

}Call it from code
The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.05.
