How this service works
Call when an agent needs a adler32 checksum of text as dec. No network and no LLM. Exact $0.01 USDC. Prefer unpaid POST /v1/sandbox/checksum-adler32-dec first.
Output
Returns the Adler-32 checksum of the submitted text as a decimal integer. The computation is deterministic, offline, and does not involve any external network calls or language model inference.
Example use cases
Data integrity check before upload
“Before I upload this config file payload, compute the Adler-32 checksum of its text content as a decimal so I can embed it in the metadata for integrity verification.”
Comparing two strings for equality
“I have two versions of a message and I want to quickly compare their Adler-32 decimal checksums to see if they match — can you compute the Adler-32 for 'The quick brown fox jumps over the lazy dog'?”
Embedding checksum in protocol header
“Generate the Adler-32 decimal checksum for this JSON payload text so I can put it in the X-Checksum header before sending it to our legacy system.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/checksum-adler32-dec?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, deterministic Adler-32 checksum of a text string returned as a decimal integer, especially in agent pipelines requiring lightweight, offline data integrity checks without any LLM overhead. Use the free sandbox endpoint (/v1/sandbox/checksum-adler32-dec) first; pay this $0.01 endpoint only when you need guaranteed production reliability or the sandbox is unavailable.
Side effects
- Missing or empty 'text' field returns a validation error
- Text exceeding 100,000 characters is rejected
- Missing or invalid API key returns an authentication error
- Malformed request body returns a 400 error

| 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. |
