How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object containing: a hex-encoded SHA-256 digest of the input text, a schema identifier ('delx/util-stable-hash/v1'), and the algorithm name ('sha256-canonical'). The hash is deterministic and canonical, meaning the same input always produces the same output.
Example use cases
Content deduplication fingerprint
“Hash this article text for me so I can check if I've already processed it: 'The quick brown fox jumps over the lazy dog. Repeated content should be caught.'”
Verifiable delivery proof
“Generate a canonical SHA-256 fingerprint of this contract clause so I can prove what version was delivered: 'Payment is due within 30 days of invoice.'”
Cache key generation
“I need a stable hash of this JSON-like text to use as a cache key — can you hash 'user_id:42,action:purchase,item:widget-A' for me?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/stable-hash?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a cheap ($0.001 USDC), verifiable, and canonical SHA-256 hash of a text string without requiring account signup. It is ideal for AI agent workflows that need deterministic content fingerprints for deduplication, caching, or integrity verification, and where payment is handled programmatically via x402/USDC on Base or Solana.
Side effects
- Missing or empty 'text' field returns an error
- Payment failure via x402 protocol blocks the request
- Overly large text inputs may be rejected or truncated
- Network timeout results in no hash returned
