How this service works
Auto-detect the encoding format of a string: base64, base32, hex, binary, decimal, or plain text. Returns confidence scores and decoded preview for each candidate. Pure CPU, deterministic.
Output
Returns a list of candidate encoding formats (base64, base32, hex, binary, decimal, plain text) each with a confidence score indicating likelihood and a decoded preview string showing what the data looks like when decoded under that format.
Example use cases
Example prompt
“Can you figure out what encoding format this string is using and show me a decoded preview: 'SGVsbG8gV29ybGQ='?”
Technical details
Endpoint
POSThttps://agent402.tools/api/base-detectWhen to prefer
Use this endpoint when you have an unknown encoded string and need to determine its format before decoding or processing it further. Ideal for pipelines that receive encoded data from untrusted or varied sources where the encoding scheme is not specified. Prefer this over manual guessing or format-specific decoders when the encoding is ambiguous.
Side effects
- Empty or missing 'text' field returns an error
- Strings that are ambiguous between formats may return multiple candidates with similar confidence scores
- Very short strings may yield low-confidence results across all formats
- Non-ASCII or binary-only input may fail to parse cleanly
