Compute API – Hash
x402
Compute API – Hash is a paid API for AI agents from compute-api-production-245d.up.railway.app, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-11).
Hashes a given string using SHA-256, SHA-512, or MD5 and returns the resulting hash value, paid per call via x402 micropayments.

How this service works
Pure computation endpoints paid per call via x402 ($0.001 USDC on Base).
Output
Returns a JSON object with a single 'hash' field containing the hex-encoded digest of the input string produced by the specified algorithm (sha256, sha512, or md5). If no algorithm is specified, sha256 is the default.
Example use cases
Verify file content integrity
“Hash the string 'invoice_12345_total_$500' using SHA-256 so I can compare it against the checksum I have on file.”
Generate password fingerprint
“Take the text 'MySecureP@ssword2024' and compute its SHA-512 hash for me.”
Quick MD5 checksum for legacy system
“I need the MD5 hash of the string 'user:admin:session42' — can you compute that for me?”
Technical details
Endpoint
POSThttps://compute-api-production-245d.up.railway.app/hash?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, pay-per-call cryptographic hash computation without running local code or setting up a library. Ideal for AI agents operating in sandboxed environments where executing native crypto functions is unavailable, or when you want an auditable external hash computation billed via x402 micropayments on Base.
Side effects
- Missing required 'text' field returns a 400 or validation error
- Invalid algorithm value outside the enum (sha256, sha512, md5) returns a validation error
- Empty string input may be accepted but yields a hash of the empty string
- Payment failure via x402 (insufficient USDC balance or missing payment header) returns 402 Payment Required
- Network timeout or service unavailability on Railway returns 5xx
