x402 Crypto Cryptography API
x402
x402 Crypto Cryptography API is a paid API for AI agents from x402-crypto.vercel.app, paid per call via x402, $0.107488/call, status unknown (last checked 2026-09-15).
Performs cryptographic operations (hashing, encoding, etc.) on input data via a path-routed POST endpoint, paid per-call via x402 micropayments

How this service works
Paid cryptocurrency API endpoints via x402 micropayments
Output
Returns a JSON object with a 'data' field containing the cryptographic result (e.g. hash digest, encoded value) from the upstream API; exact structure varies by path/operation chosen.
Example use cases
Hash password before storage
“Take the string 'MyS3cur3P@ss' and compute its SHA-256 hash using the x402 crypto API so I can store it safely.”
Verify data fingerprint
“Can you hash this document content 'Invoice #4521 total $4200' with SHA-512 using the x402 cryptography endpoint so I can compare it to the original fingerprint?”
Generate checksum for file content
“Compute an SHA-256 checksum of the text 'product_id:8821,price:99.99,qty:3' using the x402 crypto API so I can use it as an integrity check.”
Technical details
Endpoint
POSThttps://x402-crypto.vercel.app/api/cryptography/%7Bpath%7DWhen to prefer
Choose this endpoint when you need a quick, pay-per-use cryptographic hashing or encoding operation without setting up a dedicated crypto library or service. It is ideal for AI agents that occasionally need to hash, encode, or compute cryptographic values on-demand, especially in environments where installing native crypto libraries is not practical. Prefer alternatives (local crypto libraries) for high-volume or latency-sensitive use cases given the per-call cost.
Side effects
- Unsupported algorithm name causes an error or empty result
- Missing 'query' field returns a 400 validation error
- Invalid path parameter routes to a non-existent operation
- Payment failure via x402 protocol blocks the request
- Upstream API unavailable returns a 5xx error
