capi2 SHA-256 Hashing Utility
x402
capi2 SHA-256 Hashing Utility is a paid API for AI agents from capi2-demand-tools.onrender.com, paid per call via x402, $0.0005/call, status unknown (last checked 2026-09-13).
Computes the SHA-256 hash of arbitrary UTF-8 text, returning the hex digest, base64 encoding, and byte count.

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
A JSON object containing the SHA-256 hash in hex format, the same hash encoded as base64, the byte length of the input, and the algorithm name ('sha256').
Example use cases
Data integrity verification before upload
“Hash this JSON payload 'user_id:42,action:purchase,amount:99.99' with SHA-256 so I can attach the hex digest as a checksum before sending it to the API.”
Deduplication fingerprinting for content
“Give me the SHA-256 hex fingerprint of this article excerpt so I can check if I've already processed it: 'Autonomous agents are transforming enterprise workflows by...'”
Audit trail hash generation
“I need to log a tamper-evident record — compute the SHA-256 hash of 'event:login,user:alice,timestamp:2025-01-15T10:30:00Z' and return both the hex and base64 forms.”
Technical details
Endpoint
POSThttps://capi2-demand-tools.onrender.com/v1/hash/sha256When to prefer
Choose this endpoint when an AI agent needs a fast, pay-per-call SHA-256 hash without managing any cryptographic library or infrastructure — ideal for agents operating in x402-enabled micropayment environments where spinning up local crypto is impractical or not permitted.
Side effects
- Empty or missing 'text' field returns a 400 validation error
- Input too large may result in a timeout or request rejection
- Payment failure (insufficient USDC balance) returns an x402 payment-required error
- Service unavailability on Render free tier may cause cold-start delays or 503 errors
