How this service works
Call when an agent needs a fletcher32 checksum of text as dec. No network and no LLM. Exact $0.008 USDC. Prefer unpaid POST /v1/sandbox/checksum-fletcher32-dec first.
Output
Returns a Fletcher-32 checksum value as a decimal integer, computed purely server-side without any network calls or LLM inference. The result is deterministic and reproducible for the same input text.
Example use cases
Integrity check for config file content
“I need the Fletcher-32 checksum as a decimal for this config snippet: 'server_host=localhost;port=8080;timeout=30' so I can verify it hasn't changed.”
Checksum for log deduplication pipeline
“Generate a Fletcher-32 decimal checksum for this log line: '2024-01-15T10:23:45Z ERROR connection refused host=db01' — I'm using it to deduplicate log entries.”
Data fingerprint for document versioning
“What's the Fletcher-32 checksum in decimal for this paragraph: 'The quick brown fox jumps over the lazy dog. Pack my box with five dozen liquor jugs.'? I want to use it as a version fingerprint.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/checksum-fletcher32-dec?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a deterministic Fletcher-32 checksum returned as a decimal integer and cannot or prefer not to compute it locally. Prefer the free sandbox endpoint (POST /v1/sandbox/checksum-fletcher32-dec) first for testing. Use this paid endpoint in production agentic pipelines where checksum computation needs to be outsourced reliably at $0.008 USDC per call.
Side effects
- Empty or missing text field returns a validation error
- Text exceeding 100,000 characters is rejected
- Missing or invalid API key returns an authentication error
- Malformed JSON body returns a 400 bad request
