FractalAI CBOM Seal — Post-Quantum Cryptographic Bill of Materials Sealing
x402
FractalAI CBOM Seal — Post-Quantum Cryptographic Bill of Materials Sealing is a paid API for AI agents from fractalai.net.co, paid per call via x402, $0.05/call, status unknown (last checked 2026-10-13).
Accepts a Cryptographic Bill of Materials (CBOM) and returns a post-quantum signed, drand-randomness-anchored seal (Dilithium-2/ML-DSA-44) plus an additive ML-DSA-65 served signature for offline verification.

How this service works
The first AI-native Layer 1 blockchain built from scratch in Rust. Post-quantum cryptography (CRYSTALS-Dilithium), Proof of Fractal Work consensus, WASM smart contracts, and 460+ RPC endpoints. Mine FRAC tokens with fractal analysis instead of hash puzzles.
Output
Returns a JSON object containing: (1) a 'seal' object with the re-verifiable .cbomseal including the canonical claim (cbom_hash, issuer, subject, crypto_asset_count, drand_round, drand_randomness, sealed_at, algorithm), a base64 Dilithium-2/ML-DSA-44 signature from the Rust PQC node, the public key, and a seal_id; (2) a 'served_signature' object with an additive ML-DSA-65 signature over the same claim for offline verification; (3) an optional 'readiness' breakdown counting quantum-vulnerable, PQC, symmetric/hash, and unknown crypto assets; (4) a 'verify_drand_at' URL to independently check the drand round; (5) a payment settlement receipt.
Example use cases
Software supply chain CBOM attestation
“I need to seal the CBOM for our new authentication library, issued by 'SecurityTeamInc' and covering subject 'auth-lib v3.0.0', with a post-quantum ML-DSA signature and drand randomness anchor so auditors can independently re-verify it.”
Quantum-readiness compliance evidence
“Can you create a verifiable cbomseal for our fintech platform's cryptographic inventory — issuer 'FintechCo', subject 'core-payment-engine v1.4' — so we have a timestamped, post-quantum-signed record for our SOC 2 and NIST PQC compliance audit?”
Open-source library cryptographic attestation
“Seal the CBOM for the open-source project 'libcrypto-utils v0.9.2', with me as issuer 'OSS-Foundation', using Dilithium post-quantum signing and a drand beacon round so downstream users can verify the cryptographic asset inventory hasn't changed since release.”
Technical details
Endpoint
POSThttps://fractalai.net.co/api/x402/seal-cbom?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a cryptographically verifiable, post-quantum-signed attestation of a Cryptographic Bill of Materials (CBOM) that is anchored to external randomness (drand) for tamper evidence. It is specifically suited for software supply chain compliance, NIST PQC transition documentation, or any workflow requiring Dilithium (ML-DSA) signatures rather than classical ECDSA/RSA. Prefer it over generic signing APIs when dual-algorithm attestation (ML-DSA-44 + ML-DSA-65) and offline re-verifiability are required.
Side effects
- Missing or malformed CBOM input — endpoint cannot compute cbom_hash, returns 400
- Payment failure or insufficient USDC balance — x402 payment not settled, seal not issued
- Invalid issuer or subject fields — missing required claim fields cause rejection
- drand beacon unreachable — randomness anchor cannot be fetched, seal generation blocked
- PQC node signing failure — Rust node error prevents Dilithium signature issuance
- Duplicate or replayed CBOM hash — may cause idempotency conflicts if seal_id already exists
