How this service works

Machine-readable settlement service

Output

Returns a JSON object containing the decoded output of the input Base64 string, representing the original plaintext or binary data that was encoded.

Example use cases

Decode JWT payload for inspection

“I have this base64-encoded JWT payload — 'eyJ1c2VySWQiOiAxMjMsICJyb2xlIjogImFkbWluIn0=' — can you decode it so I can read the claims?”

Recover original config value

“Our secrets manager returned this base64 blob: 'bXlTZWNyZXRQYXNzd29yZA==' — decode it so I can see the actual config value.”

Inspect base64-encoded API response field

“This API response came back with a 'data' field set to 'VGhpcyBpcyBlbmNvZGVkIGRhdGE=' — please decode that so I can read what's actually in it.”

Endpoint

POSThttps://pennyrail.vercel.app/api/p/nano/encoding.base64-decode--base64-decode

When to prefer

Use this endpoint when you need a quick, programmatic Base64 decode over a micropayment API without standing up your own decode infrastructure, or when integrating into an x402-compatible agent workflow that already handles USDC micropayments. It is ideal for lightweight, one-off decode operations within agent pipelines where native decode libraries are not available or desired.

Side effects

Invalid Base64 input string causes decoding error or malformed response
Input string with incorrect padding may fail or return garbled output
Non-string input types rejected due to schema requiring string type
Binary data that is not valid UTF-8 may not render cleanly as text
Network or service unavailability returns HTTP error; payment may still be deducted
