How this service works
Bundled execution of the Decode this blob workflow - Hand the agent an opaque string - a JWT, a base64'd JSON payload, a gzip-encoded API response, a hex-encoded hash - and walk it through identifying what it is and unwrapping it layer by layer until it's human-readable. One x402 payment runs 7 underlying tools (jwt-decode, gunzip, brotli-decompress, base64, hex, json-format, hash); partial-success per step.
Output
A structured breakdown identifying the encoding type(s) of the input blob and the decoded/unwrapped content at each layer — e.g. 'This is a JWT; header: {...}, payload: {...}' or 'This is base64-encoded gzip containing {...}'.
Example use cases
Example prompt
“Can you decode this blob and tell me what it is and what's inside it: eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIiwiaWF0IjoxNTE2MjM5MDIyfQ.SflKxwRJSMeKKF2QT4fwpMeJf36POk6yJV_adQssw5c — walk me through each layer.”
Technical details
Endpoint
POSThttps://agent402.tools/api/skill/decode-blobWhen to prefer
Use this endpoint when you have an opaque string of unknown encoding and need to identify its format and extract its contents without knowing in advance whether it is a JWT, base64, hex, gzip, or other encoding. Prefer this over single-purpose decoders when you are uncertain of the encoding type or when the payload may have multiple nested layers.
Side effects
- Unrecognized encoding type — blob cannot be identified or decoded
- Malformed input — string is corrupted or truncated mid-encoding
- Encrypted content — encoding can be identified but content cannot be decrypted without a key
- Empty or null blob input — validation error returned
