Blue Cap hash.compute
x402
Blue Cap hash.compute is a paid API for AI agents from machine.soundiq.io, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).
Computes a SHA-256 cryptographic digest for UTF-8 text or base64-decoded bytes and returns the reproducible hex digest via a paid API call.

How this service works
Compute a SHA-256 digest for customer-supplied UTF-8 or base64-decoded bytes through a stable machine endpoint. Returns the reproducible digest through a receipted external execution.
Output
Returns a JSON response containing the SHA-256 hex digest of the supplied input, along with a receipted confirmation of the external execution. The digest is deterministic and reproducible for the same input bytes.
Example use cases
Data integrity check before storage
“Before I store this config file content, compute its SHA-256 digest so I can compare it later and verify nothing has changed: 'server_host=192.168.1.1\nport=8080\ndebug=false'”
Blockchain or audit trail anchoring
“I need a SHA-256 fingerprint of this transaction record so I can anchor it in our audit log — the text is: 'txn_id=TXN9921, amount=500.00, user=alice@example.com, timestamp=2024-06-01T10:00:00Z'”
Deduplication key generation
“Generate a SHA-256 hash for this product description so I can use it as a deduplication key in our database: 'Blue wireless noise-cancelling headphones, model XR-700, 30-hour battery life'”
Technical details
Endpoint
POSThttps://machine.soundiq.io/storefront/v1/capabilities/hash.compute/1.0.0/invokeWhen to prefer
Choose this endpoint when you need a stable, receipted SHA-256 hash computation over a paid API with x402 micropayment support — particularly useful in agentic workflows where a verifiable external receipt of the computation matters, or when integrating with blockchain-adjacent systems that require proof of execution alongside the digest.
Side effects
- Invalid or malformed body payload returns an error response
- Non-UTF-8 or incorrectly base64-encoded input may produce unexpected results or an error
- Payment failure (insufficient USDC balance) results in a 402 Payment Required response
- Network timeout or service unavailability returns a 5xx error
- Missing required fields (input or output objects) returns a 400 validation error
