How this service works
SHA-256 hex digest of text. Call when you need content fingerprints for agent cache keys. Returns hex digest for $0.001 USDC via x402 on Base. No network, no keys, no retention; first-party local JSON only. Results are advisory; the caller owns budgets, auth, and production controls.
Output
A JSON object containing the SHA-256 hex digest string of the provided input text. The digest is a 64-character lowercase hexadecimal string computed locally without any external network calls or data retention.
Example use cases
Cache key for agent responses
“Hash this API response body so I can use the digest as a cache key: '{"user":"alice","score":42}'”
Deduplication of ingested documents
“I'm ingesting articles and want to skip duplicates — can you get the SHA-256 hex fingerprint of this article text so I can check if I've seen it before?”
Content integrity check before storage
“Before I store this config string in the database, compute its SHA-256 hex hash so I can record it alongside the data for integrity verification later.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/sha256-hexWhen to prefer
Choose this endpoint when you need a fast, cheap, local SHA-256 hex digest with no data retention and no external dependencies — ideal for generating deterministic cache keys, deduplication fingerprints, or content checksums inside an agent pipeline. Prefer it over general-purpose crypto libraries when you want a hosted, pay-per-call micro-utility that integrates with the x402 payment protocol on Base.
Side effects
- Empty or missing 'text' field returns an error response
- Extremely large text inputs may be rejected or time out
- Payment failure via x402 protocol prevents the call from completing
- Malformed JSON request body results in a 400-level error
