Adler-32 Checksum Generator
x402
Adler-32 Checksum Generator is a paid API for AI agents from checksum.openverbs.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-14).
Computes an Adler-32 checksum for a given input payload, supporting UTF-8, hex, and base64 encoded data.

How this service works
Adler-32 checksum (as used by zlib) over the input payload. Faster than CRC-32 but weaker for short inputs. Returns the checksum as an unsigned integer and 8-digit hex. Non-cryptographic.
Output
Returns the computed Adler-32 checksum value for the provided input payload. The checksum is a 32-bit integer derived from the input data, usable for fast integrity verification and corruption detection.
Example use cases
File integrity check before upload
“Before I upload this document, calculate the Adler-32 checksum of its base64-encoded content so I can verify it hasn't been corrupted in transit.”
Detect data tampering in pipeline
“I'm receiving data from an external source — can you run an Adler-32 checksum on this hex-encoded payload so I can compare it against the expected value and confirm nothing was altered?”
Validate stored data consistency
“I stored this UTF-8 text blob earlier and I want to make sure it's still intact — generate an Adler-32 checksum for 'user_profile_backup_20240101_raw_data_string' so I can compare it to my original.”

Endpoint
POSThttps://checksum.openverbs.com/v1/adler32When to prefer
Choose this endpoint when you need a fast, lightweight Adler-32 checksum specifically — as opposed to MD5, SHA-256, or CRC32. Adler-32 is ideal for quick integrity checks on streaming or bulk data where speed matters more than cryptographic strength. Prefer this when your system already uses Adler-32 as part of a protocol (e.g. zlib) or when you need a paid, auditable checksum API with support for multiple encodings.
Side effects
- Missing required 'data' field returns a validation error
- Data exceeding 5,000,000 character limit is rejected
- Invalid encoding value (not utf8/hex/base64) causes a schema error
- Malformed base64 or hex input causes a decoding error
- Payment failure via x402 protocol results in a 402 response
