x402-zoo Checksum & Hash Calculator
x402
x402-zoo Checksum & Hash Calculator is a paid API for AI agents from x402-zoo.lolagent.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).
Computes SHA-family (e.g. SHA-256, SHA-512) or FNV-1a checksums for any caller-supplied text string.

How this service works
Calculate SHA-family hashes or an FNV-1a checksum for caller-supplied text.
Output
Returns the computed hash or checksum digest as a hex string (or equivalent encoding), along with the algorithm used and the original input text, so the caller can confirm correctness and use the digest for integrity checks or fingerprinting.
Example use cases
Data integrity fingerprinting
“Hash the string 'user:alice|role:admin|ts:1718000000' using SHA-256 so I can compare it later to detect any tampering.”
Quick FNV-1a checksum for cache key
“Give me the FNV-1a checksum of the text 'product_id=42&color=blue' — I need a fast non-crypto hash for a cache lookup key.”
Verify known hash matches input
“Compute a SHA-512 digest of 'The quick brown fox jumps over the lazy dog' so I can confirm it matches the expected value in my test suite.”
Technical details
Endpoint
GEThttps://x402-zoo.lolagent.workers.dev/api/checksumWhen to prefer
Choose this endpoint when you need a quick, serverless hash or checksum computation without standing up your own crypto library — especially useful in low-code agent workflows, test pipelines, or environments where calling a lightweight paid micro-API is simpler than importing a hashing dependency. Prefer it for SHA-family digests or FNV-1a specifically; for HMAC or bcrypt, look elsewhere.
Side effects
- Missing 'text' query parameter returns a 400 or error response
- Unsupported algorithm name returns an error indicating valid options
- Very long input strings may be truncated or rejected
- Payment failure (x402) prevents the request from being processed
