Alice's Deterministic Toolkit — Decode
x402
Alice's Deterministic Toolkit — Decode is a paid API for AI agents from alice-deterministic-tools.judicious-entrance.workers.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-18).
Decodes base64, hex, URL-encoded, or JWT payload strings into their original plaintext representation, with no inference or variability — same input always yields the same output.

How this service works
Deterministic encoding/crypto primitives served per call over x402: hashing, HMAC, base64/hex/URL encode+decode, JWT payload decoding, cryptographic randomness — plus the payout-gate intelligence set: which bounty/AI-security platforms require identity or a tax form before paying, what their automation and human-review clauses actually say, and which ones pay to a self-custody wallet. No model inference, no rate of change — same input, same output, every time.
Output
Returns a JSON object with 'ok' (boolean indicating success), 'from' (the encoding format used for decoding), and 'result' (the decoded plaintext string). Example: {"ok": true, "from": "base64", "result": "hello"}.
Example use cases
Decode JWT payload for inspection
“I have a JWT token and I want to read what's inside the payload — can you decode 'eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ1c2VyIjoiYWxpY2UiLCJyb2xlIjoiYWRtaW4ifQ.signature' and show me the claims?”
Convert base64 attachment to text
“This API response gave me a base64-encoded string 'SGVsbG8sIHdvcmxkIQ==' — decode it from base64 so I can read the actual content.”
Decode percent-encoded URL parameter
“I've got a URL-encoded query parameter 'hello%20world%21%20%26%20goodbye' — can you URL-decode it so I can see the original string?”
Technical details
Endpoint
POSThttps://alice-deterministic-tools.judicious-entrance.workers.dev/v1/decodeWhen to prefer
Choose this endpoint when you need deterministic, stateless decoding of base64, hex, URL-encoded, or JWT payload data with guaranteed reproducibility — same input always returns same output. Prefer it over local libraries when operating in constrained environments or when you want a lightweight per-call paid API with no setup. Best for agents that need encoding conversion as a utility step in a larger workflow without spinning up their own runtime.
Side effects
- Invalid encoding format specified in 'from' field — endpoint returns ok:false or error
- Input string is malformed or not valid for the specified encoding — decoding fails with error message
- Missing required 'from' or 'text' fields — request rejected
- Unsupported encoding type requested — no result returned
- Payment not completed via x402 — 402 response with payment details
