x402
RIPEMD-160 Hex Digest is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-01).

How this service works
Call when an agent needs a ripemd160 digest of text, encoded as hex. No network and no LLM. Exact $0.003 USDC. Prefer unpaid POST /v1/sandbox/digest-ripemd160-hex first.
Output
Returns a 40-character lowercase hexadecimal string representing the RIPEMD-160 digest of the provided input text. No network calls are made; computation is entirely local and deterministic.
Example use cases
Bitcoin address derivation step
“I need the RIPEMD-160 hex digest of this SHA-256 output string '6a2a9b5d3c1e8f4b2d9c7a0e5b3f1d8c2e6a4b9d7c5f3a1b8e6d4c2f0a7b5e3' to use in a Bitcoin address generation pipeline — can you compute that?”
Verify legacy hash fingerprint
“Can you hash the text 'syntexa-agent-token-2024' with RIPEMD-160 and return it as hex so I can compare it against a stored fingerprint in our old system?”
Content integrity tag generation
“I want to generate a RIPEMD-160 hex digest of this document excerpt 'Terms of service version 3.2 updated April 2024' to use as a compact integrity tag — can you do that?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-ripemd160-hex?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need a RIPEMD-160 hash (not SHA-256, MD5, or SHA-1) encoded as hex — common in Bitcoin/blockchain address derivation, legacy compatibility systems, or when interoperability with RIPEMD-160-based protocols is required. Prefer the free sandbox endpoint POST /v1/sandbox/digest-ripemd160-hex for testing before incurring the $0.003 USDC cost.
Side effects
- Empty or missing 'text' field returns a validation error
- Input text exceeding 100,000 characters is rejected
- Missing or invalid payment (x402) results in a 402 Payment Required response
- Malformed JSON body returns a 400 Bad Request
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. |
