How this service works
Call when an agent needs a crc32c checksum of text as dec. No network and no LLM. Exact $0.008 USDC. Prefer unpaid POST /v1/sandbox/checksum-crc32c-dec first.
Output
Returns a CRC32C checksum of the input text encoded as a decimal integer string. The computation is performed locally with no network calls or LLM involvement, guaranteeing deterministic, reproducible results for the same input.
Example use cases
File integrity verification pipeline
“Compute the CRC32C checksum in decimal for this data block so I can compare it against the stored checksum and confirm the file hasn't been corrupted: 'user_id=42;email=alice@example.com;role=admin'”
Protocol message validation
“I need the CRC32C decimal checksum for the message 'ORDER:12345:USD:99.99:2024-06-01' to embed in a network packet header for integrity checking.”
Database record fingerprinting
“Calculate the CRC32C decimal hash for the string 'ProductSKU:AB-1023|qty:500|warehouse:NYC' — I need to store it as a fingerprint so I can detect any future changes to this record.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/checksum-crc32c-dec?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a CRC32C checksum returned specifically as a decimal integer (not hex, base64, or other encodings). Prefer the free sandbox endpoint POST /v1/sandbox/checksum-crc32c-dec first; use this paid endpoint when the sandbox is unavailable or rate-limited. Use this over SHA-based endpoints when CRC32C compatibility with systems like Google Cloud Storage, iSCSI, or Btrfs is required.
Side effects
- Missing or empty 'text' field returns a validation error
- Text exceeding 100,000 characters is rejected
- Missing or empty 'key' field returns a validation error
- Payment of exactly $0.008 USDC must be provided via x402 protocol or request is rejected
- Invalid JSON body returns a parse 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. |
