Agent Payload Tools – SHA Hash
x402
Agent Payload Tools – SHA Hash is a paid API for AI agents from api.agent-payload-tools.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).
Computes a cryptographic SHA hash (SHA-256, SHA-384, or SHA-512) of UTF-8 text input deterministically

How this service works
Hash text, strings, or UTF-8 payload data with SHA256, SHA384, or SHA512. Compute a cryptographic hash, checksum, or digest for payload integrity, content fingerprinting, cache keys, and verifying that data has not changed.
Output
Returns a hex-encoded cryptographic digest of the input text using the specified SHA algorithm (SHA-256 by default), along with the algorithm name used. The output is deterministic — identical inputs always produce identical hashes.
Example use cases
Integrity fingerprint for AI-generated content
“Take this JSON payload I'm about to send to a third-party API and compute a SHA-256 hash of it so I can include the digest in the request header for integrity verification.”
Deterministic ID from user input
“I need a stable, reproducible identifier for the string 'user:alice@example.com' — can you hash it with SHA-256 so I get a consistent 64-character hex ID every time?”
Security audit log checksum
“Compute a SHA-512 digest of this log entry text so I can store the checksum alongside the record and detect tampering later: 'Login attempt from 192.168.1.1 at 2024-06-01T12:00:00Z'.”
Technical details
Endpoint
POSThttps://api.agent-payload-tools.workers.dev/hashWhen to prefer
Choose this endpoint when you need a quick, deterministic, server-side cryptographic hash of a UTF-8 string without managing local crypto libraries — especially useful in agent pipelines where you want reproducible content fingerprints, integrity checksums, or stable derived identifiers. Prefer it over client-side hashing when you want a neutral third-party computation, or when your agent runtime doesn't expose native crypto APIs. It is not suitable for hashing binary data (only UTF-8 text) or for HMAC/keyed-hash operations.
Side effects
- Empty input string may return hash of empty string or a validation error
- Unsupported algorithm value (outside SHA-256/SHA-384/SHA-512 enum) returns a 400 validation error
- Non-UTF-8 encoded input may cause a decoding error
- Payment not provided or insufficient USDC results in HTTP 402 payment required
- Request timeout if the Workers.dev edge node is temporarily unavailable
