Delx Bytes SHA-256 Base64
x402
Delx Bytes SHA-256 Base64 is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-15).
Computes a SHA-256 hash of base64-encoded bytes and returns the hex digest along with the byte count.

How this service works
SHA-256 of base64-decoded bytes. Call when hashing binary payloads agents already hold as base64. Returns sha256 and nbytes as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.
Output
Returns a JSON object containing the SHA-256 hex digest of the decoded bytes ('sha256'), the number of bytes in the decoded payload ('nbytes'), and a schema version identifier ('schema'). Example: {nbytes: 5, schema: 'delx/util-bytes-sha256-b64/v1', sha256: '2cf24dba5fb0a30e26e83b2ac5b9e29e1b161e5c1fa7425e73043362938b9824'}.
Example use cases
File integrity check before upload
“I'm about to store this base64-encoded file blob — can you compute its SHA-256 hash first so I can compare it after retrieval and confirm nothing got corrupted? The base64 is 'SGVsbG8gV29ybGQ='.”
Content deduplication fingerprinting
“I have a base64-encoded image payload and I need a SHA-256 fingerprint so I can check if this exact content already exists in my database before saving it again. Base64 data is 'iVBORw0KGgo='.”
Audit trail hash generation
“For my audit log, I need the SHA-256 digest of this base64-encoded binary record so I can store a tamper-evident hash alongside the entry. Here's the base64: 'dGVzdCBkYXRh'.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/bytes-sha256-b64When to prefer
Choose this endpoint when you need to compute a SHA-256 hash of binary data that is already in base64-encoded form — common after reading files, images, or binary payloads from APIs that return base64. It combines base64 decoding and SHA-256 hashing in a single call, saving a step compared to decoding locally first. Prefer over generic hashing services when working within the Delx agent infrastructure ecosystem where x402 micropayment billing is already in place.
Side effects
- Invalid base64 string causes decoding error
- Empty or missing 'base64' field returns validation error
- Malformed JSON request body returns 400
- Very large payloads may exceed size limits
- Non-string values for 'base64' field rejected
