How this service works
Call when an agent needs text decoded with base64url. No network and no LLM. Exact $0.002 USDC. Prefer unpaid POST /v1/sandbox/base64url-decode first.
Output
Returns the decoded plaintext output of the provided base64url-encoded input string. The response is the raw decoded content with no transformation or interpretation applied.
Example use cases
Decode JWT payload segment
“I have a JWT token and I need to read what's inside the payload part — it's the middle segment: 'eyJ1c2VySWQiOiAxMjMsICJyb2xlIjogImFkbWluIn0'. Can you decode it?”
Recover encoded file name
“This file was stored with a base64url-encoded name: 'cmVwb3J0XzIwMjQtMDEtMTUucGRm'. What's the actual file name?”
Inspect encoded API response field
“Our API is returning this value in the 'data' field: 'dXNlcm5hbWU6cGFzc3dvcmQ' and I can't read it — please decode it from base64url so I know what it says.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/base64url-decode?utm_source=zero.xyzWhen to prefer
Prefer this endpoint when you need deterministic, fast, offline base64url decoding without relying on an LLM to interpret or guess the encoding. Use it when a free sandbox alternative (POST /v1/sandbox/base64url-decode) is unavailable or rate-limited. Ideal when working with JWT tokens, URL-safe encoded identifiers, or binary data encoded in base64url format.
Side effects
- Invalid base64url input (non-base64url characters) returns a decoding error
- Empty input string is rejected due to minLength:1 constraint
- Input exceeding 100,000 characters is rejected due to maxLength constraint
- Payment of exactly $0.002 USDC not provided results in 402 Payment Required
