X Pay SHA-256 Hash API
x402
X Pay SHA-256 Hash API is a paid API for AI agents from www.api-xpay.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).
Computes a SHA-256 hash of a provided HTTP request body payload, returning the hex digest, paid per-call via USDC on Base using x402.

How this service works
Pay-per-request utility APIs powered by x402 using USDC on Base.
Output
Returns a JSON object containing: the SHA-256 hex hash string of the input body, the algorithm name ('sha256'), the payment asset ('USDC'), the network ('base'), and a boolean success flag.
Example use cases
Deduplication fingerprinting for event payloads
“I need to deduplicate incoming webhook events — can you SHA-256 hash this JSON body so I can compare fingerprints and skip duplicates? Body is {"event":"order.created","orderId":"abc123"}, sent as JSON via POST.”
Data integrity check before storage
“Before I save this form submission to the database, hash the JSON body {"name":"Jane","email":"jane@example.com"} with SHA-256 so I can store the checksum alongside the record for later integrity verification.”
Cache key generation from request body
“Generate a SHA-256 hash of this API request body — {"query":"top products","limit":10} as JSON via POST — so I can use the digest as a cache key and avoid re-running expensive lookups for identical requests.”
Technical details
Endpoint
POSThttps://www.api-xpay.com/x402/hashWhen to prefer
Choose this endpoint when you need a simple, pay-per-use SHA-256 hashing primitive without setting up your own crypto infrastructure, especially in blockchain-native or x402-enabled agent workflows where USDC micropayments on Base are already in use. It is ideal for lightweight, stateless hashing of JSON, form, or text payloads within automated pipelines.
Side effects
- Missing required 'input' object returns a 400 validation error
- Invalid bodyType enum value causes schema rejection
- Empty or malformed body object may produce an unexpected hash or error
- Payment failure (insufficient USDC balance) prevents request from being processed
- Network congestion on Base may delay payment confirmation and response
