How this service works
Paid x402 utilities and live intelligence for autonomous agents: hashing/encoding plus public web lookup, domain intelligence, API discovery audit, evidence extraction and x402 health.
Output
Returns a JSON object containing the SHA-512 hash as a hex string, the same hash encoded in base64, the byte length of the input, and the algorithm name ('sha512').
Example use cases
Data integrity fingerprinting
“Generate a SHA-512 hash of this document content so I can verify it hasn't been tampered with later: 'The contract terms are as follows...'”
Password hashing before storage
“Hash the string 'MySecureP@ssword123' with SHA-512 and give me the hex and base64 results so I can store it safely.”
API payload signing checksum
“Compute the SHA-512 digest of this JSON payload text so I can include it as a checksum header: '{"user":"alice","amount":100}'”
Technical details
Endpoint
POSThttps://capi2-demand-tools.onrender.com/v1/hash/sha512When to prefer
Choose this endpoint when you need a paid, metered SHA-512 hash via the x402 micropayment protocol — ideal for autonomous agents that require cryptographic hashing without managing their own compute infrastructure, or when you need both hex and base64 output in a single call.
Side effects
- Empty or missing 'text' field returns a validation error
- Extremely large payloads may time out on the Render.com free tier host
- Non-UTF-8 encoded input may produce unexpected results
- Service cold-start latency on Render free tier can cause occasional timeout on first call
