SHA-256 Hex Digest of Raw Hex Bytes
x402
SHA-256 Hex Digest of Raw Hex Bytes is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.007/call, status unknown (last checked 2026-09-29).
Computes a SHA-256 digest of input data provided as a hex-encoded byte string and returns the result as a hex-encoded digest

How this service works
Call when an agent needs a sha256 digest of hex bytes, encoded as hex. Exact $0.007 USDC. Prefer unpaid POST /v1/sandbox/digest-sha256-hex-rawhex first.
Output
Returns a hex-encoded SHA-256 digest string computed by treating the input text as raw hex bytes and hashing the underlying binary data. The result is a 64-character lowercase hex string representing the 256-bit digest.
Example use cases
Verify integrity of raw binary payload
“I have a chunk of binary data represented in hex as 4a6f736570680d0a — can you run SHA-256 on it as raw bytes and give me back the hex digest so I can compare it against a checksum?”
Generate cryptographic fingerprint for blockchain data
“Take this raw transaction data in hex format — 0100000001abc123 — hash it with SHA-256 treating it as raw bytes, and return the hex digest I can use as a transaction fingerprint.”
Hash firmware image bytes for integrity check
“I have a firmware image expressed as a hex byte string: ff4e3d2c1b0a — please compute the SHA-256 hash treating those as raw bytes and return the result in hex so I can validate it against the expected value.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-sha256-hex-rawhex?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to SHA-256 hash data that is provided as a raw hex byte string and want the output returned as hex. Choose this over generic SHA-256 endpoints when your input is already hex-encoded binary (e.g. raw transaction bytes, binary blobs, firmware images) rather than plain text. If a free sandbox endpoint at POST /v1/sandbox/digest-sha256-hex-rawhex is available, prefer that first to avoid the $0.007 USDC charge.
Side effects
- Input text is not valid hex (odd length or non-hex characters) — likely returns 400 or validation error
- Input text or key exceeds maximum length limits (512 chars for key, 100000 chars for text) — returns error
- Payment of $0.007 USDC not provided — returns 402 Payment Required
- Network timeout or service unavailability — returns 5xx error
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| key | string | HMAC secret. Required on HMAC SKUs. Omit it for plain digests and checksums. The key is not stored. |
| text | string | Message to digest. For raw-hex SKUs this is hex bytes; for utf16 or latin1 SKUs it is decoded with that encoding. Otherwise it is UTF-8 text. |
