How this service works

Quality-scored paid utility APIs for AI agents over x402 on Base USDC.

Output

Returns a JSON object with a 'result' key containing a 'text' field holding the decoded plaintext string corresponding to the input Base64 data.

Example use cases

Decode JWT payload contents

“I have this JWT token — can you decode the payload part for me? It's the middle section: 'eyJ1c2VySWQiOiAxMjMsICJyb2xlIjogImFkbWluIn0='”

Read base64-encoded config data

“My app returned this base64 blob from the config endpoint: 'eyJob3N0IjoibG9jYWxob3N0IiwicG9ydCI6NTQzMn0=' — can you decode it so I can see what settings are in there?”

Reveal obfuscated email in scraped HTML

“I scraped a webpage and found this base64 string where the contact email should be: 'c3VwcG9ydEBleGFtcGxlLmNvbQ==' — decode it for me please.”

When to prefer

Use this endpoint when you need a reliable, micropayment-gated Base64 decode operation within an AI agent workflow on Base USDC, particularly when you want quality-scored utility APIs and are already operating in the x402 payment ecosystem. Prefer it over local decoding when you need a hosted, auditable decode call or when your agent runtime lacks native Base64 support.

Side effects

Invalid or malformed base64 input returns an error
Input string exceeds 200,000 character limit
Empty string input rejected (minLength: 1)
Payment failure via x402 if USDC balance insufficient
