Delx Commerce — SHA-256 Hash of Base64-Encoded Bytes
x402
Delx Commerce — SHA-256 Hash of Base64-Encoded Bytes is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-02).
Computes the SHA-256 hash of base64-encoded bytes and returns the hex digest along with the byte count.

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 the SHA-256 hex digest of the decoded bytes, the number of bytes, and a schema version string (e.g. {"sha256": "2cf24dba...", "nbytes": 5, "schema": "delx/util-bytes-sha256-b64/v1"}).
Example use cases
Integrity check before storing file
“I just encoded a binary file as base64 — can you get the SHA-256 hash of 'dGVzdCBmaWxlIGNvbnRlbnQ=' so I can store a checksum alongside it?”
Verify downloaded binary matches expected hash
“I downloaded a file and base64-encoded it to get 'SGVsbG8gV29ybGQ='. Can you compute its SHA-256 so I can check it matches the expected digest?”
Fingerprint binary payload for deduplication
“I have a base64-encoded binary payload 'YWJjZGVmZ2g=' and I need its SHA-256 fingerprint to detect duplicate uploads in my pipeline.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/bytes-sha256-b64?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a pay-per-use, no-signup SHA-256 hash of binary data that is already base64-encoded, especially in agent pipelines where USDC micropayments via x402 are acceptable and verifiable delivery is required. Prefer over self-hosted hashing when you want a trustless, on-chain-payment-verified cryptographic primitive.
Side effects
- Invalid base64 string returns an error response
- Missing 'base64' field in request body causes a validation error
- Empty base64 string may return a zero-byte result or error
- Payment not provided or insufficient USDC results in HTTP 402 response
