x402
Adler-32 Hex Checksum is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.009/call, status unknown (last checked 2026-10-02).
Computes the Adler-32 checksum of a given text string and returns the result as a hexadecimal string, with no network calls or LLM involvement.

How this service works
Call when an agent needs a adler32 checksum of text as hex. No network and no LLM. Exact $0.009 USDC. Prefer unpaid POST /v1/sandbox/checksum-adler32-hex first.
Output
Returns the Adler-32 checksum of the submitted text encoded as a hexadecimal string. The response is deterministic — identical input always produces identical output. No side effects, no network calls, no LLM inference involved.
Example use cases
Data integrity check before upload
“Before I upload this config file content, compute the Adler-32 hex checksum of the string 'server=localhost;port=5432;db=myapp' so I can compare it after transfer.”
Reproducible build artifact fingerprint
“I need the Adler-32 checksum in hex for the string 'build:v2.3.1-stable' so I can stamp it into our release metadata.”
Checksum for lightweight deduplication
“Can you run an Adler-32 hex checksum on this text 'The quick brown fox jumps over the lazy dog' so I can use it as a dedup key in my pipeline?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/checksum-adler32-hex?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, deterministic Adler-32 checksum in hexadecimal format for a text string — especially in pipelines where reproducibility and exactness matter. Prefer this over CRC32c or Fletcher-16 siblings when Adler-32 specifically is required by your protocol or downstream system. Use the free sandbox endpoint (/v1/sandbox/checksum-adler32-hex) during development to avoid charges.
Side effects
- Missing or empty 'text' field returns a validation error
- Text exceeding 100,000 characters is rejected
- Missing or invalid API key causes authentication failure
- Malformed JSON body returns a 400 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. |
