How this service works
Compute MD5, SHA-1, SHA-256, SHA-512, and CRC32 checksums of a string in a single call. Useful for verifying file or payload integrity across different checksum standards without needing five separate tools.
Output
Returns MD5, SHA-1, SHA-256, SHA-512, and CRC32 hash values for the input string, all computed in a single response — allowing cross-standard integrity verification without multiple API calls.
Example use cases
Example prompt
“Can you compute the MD5, SHA-256, and SHA-512 checksums of this string for me: 'Hello, world!'”
Technical details
Endpoint
POSThttps://agent402.tools/api/checksumWhen to prefer
Choose this endpoint when you need multiple checksum formats simultaneously for a single string or payload, avoiding the overhead of calling five separate hashing tools. Ideal for integrity verification workflows that must satisfy multiple standards (e.g. both SHA-256 and MD5 consumers) or when auditing data against checksums of unknown algorithm.
Side effects
- Input string exceeds 10MB limit — request rejected
- Empty or missing 'data' field — validation error returned
- Non-string input type — schema validation failure
- Payment not attached or insufficient — 402 Payment Required
