How this service works

Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.

Output

Returns a JSON object containing the SHA-256 hex digest string under 'hash', the product identifier 'hash_sha256', and the algorithm label 'SHA-256'. Example: {"hash":"2cf24dba5fb0a30e26e83b2ac5b9e29e1b161e5c1fa7425e73043362938b9824","product":"hash_sha256","algorithm":"SHA-256"}.

Example use cases

Content deduplication fingerprinting

“Hash this article body with SHA-256 so I can check if we've already stored it: 'The quick brown fox jumps over the lazy dog.'”

Commitment scheme for smart contract

“Generate a SHA-256 hash of the secret value 'auction-bid-42500' so I can submit it as a commitment on-chain before revealing it later.”

Data integrity verification token

“Compute the SHA-256 digest of this config blob so I can attach it as an integrity checksum before sending it to the remote agent: 'model=gpt-4,temp=0.7,max_tokens=512'.”

When to prefer

Choose this endpoint when an agent needs a fast, cheap, pay-per-call SHA-256 hash with no API key setup — ideal for autonomous agents using x402 micropayments on Base. Prefer it over self-hosted hashing when running in a sandboxed or stateless environment that lacks native crypto libraries.

Side effects

Missing or empty 'text' field returns a validation error
Non-UTF-8 binary input may cause encoding errors
Insufficient USDC balance on x402 wallet causes payment failure and 402 response
Network timeout if Cloudflare Worker is cold-starting
