CRC16 Checksum (Decimal) Calculator
x402
CRC16 Checksum (Decimal) Calculator is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-29).
Computes the CRC16 checksum of an input text string and returns the result as a decimal integer, with no network calls or LLM involved.

How this service works
Call when an agent needs a crc16 checksum of text as dec. No network and no LLM. Exact $0.002 USDC. Prefer unpaid POST /v1/sandbox/checksum-crc16-dec first.
Output
Returns the CRC16 checksum of the provided text as a decimal integer. No network lookups or AI inference are involved; the result is deterministic and reproducible for any given input.
Example use cases
Data integrity check before transmission
“Before I send this config payload over the wire, compute the CRC16 checksum of 'host=localhost;port=5432;dbname=mydb' so I can include it in the header for the receiver to validate.”
Verify downloaded file content
“I downloaded a text file and the expected CRC16 decimal checksum was 54321 — can you compute the CRC16 of its contents so I can confirm they match?”
Checksum embedded firmware string
“I need to embed a CRC16 integrity tag in my firmware manifest. Can you compute the decimal CRC16 of the string 'fw_version=2.4.1;board=esp32;build=20240501'?”

Endpoint
POSThttps://agentshelf.syntexa.ch/v1/checksum-crc16-dec?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a deterministic, fast, server-side CRC16 decimal checksum without implementing the algorithm locally. Especially useful in agentic pipelines where local computation is unavailable or undesirable, and where the exact $0.002 USDC per-call cost is acceptable. Try the free sandbox endpoint (POST /v1/sandbox/checksum-crc16-dec) first to validate behavior before paying.
Side effects
- Empty or missing 'text' field returns a validation error
- Text exceeding 100,000 characters is rejected
- Missing or invalid API key returns 401/402 unauthorized
- 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. |
