How this service works
Recent CVE highlights + CISA known-exploited-vulnerability entries, relayed from public sources (NVD, CISA KEV)
Output
A JSON payload containing current threat intelligence data, a cryptographic signature over the payload, and an EIP-712 PayloadAttestation provenance stamp. The response identifies itself as the 'threat-intel' feed and is verified to be tamper-evident. The payload size determines the exact per-KB cost around $0.025879 USDC.
Example use cases
Example prompt
“Pull the latest threat-intel feed from BYTE Library right now — I need the cryptographically signed, provenance-stamped payload and I'm happy to pay the USDC per-call fee via my Base wallet.”
Technical details
Endpoint
GEThttps://x402.payperbyte.io/feeds/threat-intelWhen to prefer
Choose this endpoint when you need threat intelligence data that is cryptographically signed and provenance-stamped for verifiability — especially in agentic pipelines where data integrity and non-repudiation matter. Prefer it over unsigned threat intel APIs when your workflow requires EIP-712 attestation, or when you want to pay per call with USDC on Base rather than managing API keys. Ideal for security automation agents that need trustworthy, tamper-evident data.
Side effects
- Payment insufficient or rejected — 402 response if USDC payment not provided or below floor price
- Invalid or missing x402 payment header — endpoint returns 402 requiring wallet-based payment
- Network or RPC issues on Base (eip155:8453) causing settlement failure
- Feed temporarily unavailable — upstream threat intelligence source outage
- Malformed response if feed schema changes — agent should validate 'feed' field equals 'threat-intel'
- Signature verification failure on client side if EIP-712 parsing is incorrect
