Endpoint

POSThttps://agent402.tools/api/base64

When to prefer

Use this endpoint when an agent needs a quick, stateless Base64 encode or decode operation without setting up a local utility, especially when working inside an x402 payment-enabled workflow and the input is under 100KB. Handles URL-safe Base64 decode automatically, which is useful for JWT or OAuth token inspection.

Side effects

Input text exceeds 100KB limit — request rejected
Invalid mode value (not 'encode' or 'decode') — may default to encode or return error
Malformed Base64 input on decode — returns error or garbled output
Missing 'text' field in request body — returns validation error
