TripGuard Fare Intelligence – Cryptographic Hash
x402
TripGuard Fare Intelligence – Cryptographic Hash is a paid API for AI agents from tripguard-fare-intel.onrender.com, paid per call via x402, $0.12/call, status unknown (last checked 2026-10-11).
Computes cryptographic digests (SHA-256, SHA-512, Keccak-256) of an input string, returning hex-encoded hash values and byte length.

How this service works
Real-time airfare intelligence for AI travel-booking agents: flight price-drop prediction, fare-fraud and deal-legitimacy verification, and verified booking links for any route and date. Pay-per-call in USDC on Base. No API key.
Output
Returns a JSON object containing hex-encoded digests for each requested algorithm (sha256, sha512, keccak256) and the byte length of the input string.
Example use cases
Verify data integrity before storage
“Take this JSON payload and compute its SHA-256 hash so I can store the checksum alongside the record and verify it hasn't been tampered with later.”
Blockchain-compatible Keccak-256 fingerprint
“I need the Keccak-256 digest of the string 'Transfer:0xABC:100ETH' — it needs to match what an Ethereum smart contract would produce.”
Multi-algorithm digest comparison
“Run 'mySecretData42' through SHA-256, SHA-512, and Keccak-256 all at once and show me all three digests so I can pick which one to use in my protocol.”

Endpoint
POSThttps://tripguard-fare-intel.onrender.com/hash?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a pay-per-call, keyless cryptographic hashing service accessible over HTTP, especially when you need Keccak-256 for Ethereum/blockchain compatibility alongside standard SHA-256 or SHA-512 digests in a single call.
Side effects
- Empty input string rejected (minLength:1 violated)
- Input string exceeds 65536 character limit
- Invalid algorithm name in algorithms array returns validation error
- Malformed JSON body causes 400 Bad Request
- Payment not provided or insufficient USDC causes 402 Payment Required
