x402 Utility Tools — Hash Text
x402
x402 Utility Tools — Hash Text is a paid API for AI agents from x402-utils.558686.xyz, paid per call via x402, $0.0001/call, status down (last checked 2026-10-25).
Computes one or more cryptographic hashes (e.g. SHA-256) over an input string and returns the hex digests along with input byte size.

How this service works
A compact x402 utility surface for agents that need cheap, repeatable non-LLM transformations before spending on heavier routes: CSV cleanup, JSON Schema checks, timestamp conversion, JWT decode, URL normalization, hashes, codecs, and text utilities.
Output
Returns a JSON object with ok:true, the tool name, the original input echoed back, a map of algorithm names to their hex digest strings, and the input byte count. The result is deterministic — same input always yields the same hashes.
Example use cases
Integrity fingerprint before storage
“Before I store this config blob, hash it with SHA-256 so I can detect any tampering later — the text is: '{"env":"prod","key":"abc123"}'.”
Multi-algorithm comparison for a token
“Run SHA-1, SHA-256, and SHA-512 on the string 'my-secret-token' so I can compare the digest lengths and pick the right algorithm for my project.”
Deduplication key for log lines
“Generate a SHA-256 hash of this log line so I can use it as a deduplication key: '2024-06-01T12:00:00Z ERROR connection timeout host=db.internal'.”
Technical details
Endpoint
POSThttps://x402-utils.558686.xyz/v1/tools/hash-text?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a cheap ($0.002), deterministic, server-side hash of a text string without spinning up a local crypto library — especially useful in sandboxed agent environments, for multi-algorithm comparison in one call, or when you need the input byte size alongside the digest. Prefer a local crypto call if latency or cost at very high volume matters.
Side effects
- Unsupported algorithm name causes an error or omission in the hashes map
- Empty text input may return zero-byte result or error
- Invalid JSON body returns a 400-level error
- Payment not attached or insufficient USDC causes a 402 response before processing
