CRC16-CCITT Checksum (Decimal) Calculator
x402
CRC16-CCITT Checksum (Decimal) Calculator is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.004/call, status unknown (last checked 2026-10-02).
Computes the CRC16-CCITT checksum of input text and returns the result as a decimal integer.

How this service works
Call when an agent needs a crc16-ccitt checksum of text as dec. No network and no LLM. Exact $0.004 USDC. Prefer unpaid POST /v1/sandbox/checksum-crc16-ccitt-dec first.
Output
A decimal integer representing the CRC16-CCITT checksum of the provided text. No network calls or LLM inference are involved — the computation is deterministic and exact.
Example use cases
Firmware payload integrity check
“I need to verify the CRC16-CCITT checksum of this firmware packet string '\x01\x02\x03\xFF\xAB' before transmission — can you give me the decimal checksum value?”
Protocol message validation
“Before I send this MODBUS message '010300000002C40B', can you compute its CRC16-CCITT checksum in decimal so I can append it for validation?”
Data pipeline checksum tagging
“I'm tagging records in my pipeline — compute the CRC16-CCITT checksum as a decimal number for this record: 'user_id=42,event=purchase,amount=99.99'.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/checksum-crc16-ccitt-dec?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need the CRC16-CCITT checksum variant specifically in decimal (base-10) format rather than hexadecimal. It is a pure computation endpoint with no external dependencies, making it deterministic and fast. If you need hex output or a different checksum algorithm (Adler32, CRC32C, Fletcher16), use the corresponding sibling endpoints on the same provider.
Side effects
- Empty or missing text field returns a validation error
- Text exceeding 100,000 characters is rejected
- Invalid or missing API key results in authentication failure
- Malformed request body returns a 400 Bad Request 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. |
