Security Math Checksum
x402
Security Math Checksum is a paid API for AI agents from security-math.x402tookit.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-21).
Computes non-cryptographic checksums (CRC-32, CRC-32C, Adler-32, FNV-1/1a 32/64-bit, MurmurHash3 x86_32) for text or hex-encoded bytes

How this service works
CRC-32, CRC-32C, Adler-32, FNV-1/1a (32 and 64 bit) and MurmurHash3 x86_32 of text or hex bytes. Not cryptographic.
Output
A JSON object containing results for each requested algorithm (or all algorithms if 'all' is selected), each with hex and decimal representations of the checksum. Also includes metadata fields like asOf, secure flag, source, and reasons.
Example use cases
File integrity deduplication check
“Compute the CRC-32 checksum for the text 'user_session_data_v2' so I can use it as a fast integrity tag in my deduplication pipeline.”
Hash table key generation
“Give me the FNV-1a 64-bit hash of the string 'product:SKU-98123' — I need it as both hex and decimal to use as a hash table key.”
MurmurHash3 with custom seed
“Run MurmurHash3 x86_32 on the hex bytes '68656c6c6f' using seed 42 and show me the result in hex and decimal.”

Endpoint
GEThttps://security-math.x402tookit.com/checksum?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, non-cryptographic checksums for data integrity, deduplication, hash-table keying, or fingerprinting — especially when you want to compare multiple algorithms side by side (CRC-32, CRC-32C, Adler-32, FNV variants, MurmurHash3) in a single call. Prefer over cryptographic hash endpoints when speed and uniformity matter more than collision resistance or security. Ideal for agents working on data pipeline validation, caching keys, or protocol-level integrity checks where MD5/SHA is overkill.
Side effects
- Missing required 'data' query parameter returns an error
- Input exceeding 4000 characters may be rejected
- Invalid algorithm name returns an error listing valid options
- Invalid inputType (not 'text' or 'hex') causes a parse error
- Malformed hex string when inputType=hex causes a parse error
- Seed value outside 0–4294967295 for MurmurHash3 causes an error
- Payment failure (x402) results in 402 response before computation
