How this service works
Base64 decoder API. Decodes a base64 string back to UTF-8 text instantly and correctly, avoiding the padding and charset errors LLMs make when decoding base64 by hand.
Output
Returns the decoded UTF-8 plain text string corresponding to the provided base64 input. Returns a 400 error if the input text field is missing, not a string, or contains invalid base64.
Example use cases
Decoding an encoded API response field
“This API response has a base64-encoded 'message' field: 'SGVsbG8gZnJvbSB0aGUgc2VydmVyIQ=='. Can you decode it so I can read what it says?”
Reading a base64-encoded JWT payload
“I have this base64 JWT payload segment — 'eyJ1c2VySWQiOiAxMjMsICJyb2xlIjogImFkbWluIn0=' — can you decode it to see what's inside?”
Recovering text from encoded config file
“My config file has this base64 value for the secret field: 'bXlTdXBlclNlY3JldFBhc3N3b3Jk'. Decode it so I know what the actual secret string is.”
Technical details
Endpoint
POSThttps://x402.outpimp.com/base64DecodeWhen to prefer
Prefer this endpoint when an AI agent needs to reliably decode base64 strings without the padding or charset errors that LLMs commonly make when attempting to decode base64 manually. Ideal for pipelines that frequently encounter base64-encoded fields in API responses, config files, or data blobs.
Side effects
- 400 if 'text' field is missing from the request body
- 400 if 'text' is not a string type
- 400 if the input is not valid base64 (e.g. illegal characters, wrong padding)
- Payment failure if USDC balance is insufficient for the $0.01 per-call fee
