How this service works
66 pay-per-call APIs: AI text/image generation ($0.01), Polymarket odds, crypto prices, DeFi yields, FX rates, weather, IP/geo, FBI wanted, SEC tickers, clinical trials, 250M academic papers, Stack Overflow, meme-coin launchpads (pump.fun, Clanker, Four.meme, SunPump), tokenized stocks, Solana top 100, and 40+ more. $0.005/call standard. USDC on Base and Solana via x402.
Output
Returns a JSON object containing the result of the base64 operation — either the Base64-encoded version of the input string or the decoded plaintext, depending on the 'op' parameter chosen.
Example use cases
Encode credentials for HTTP header
“Base64-encode the string 'myuser:mypassword123' so I can use it in a Basic Auth header.”
Decode an incoming API token payload
“I got this base64 string from an API response — can you decode it back to readable text? The value is 'eyJ1c2VyIjoiYWxpY2UiLCJyb2xlIjoiYWRtaW4ifQ=='”
Encode binary data for JSON embedding
“Encode the text 'SELECT * FROM users WHERE id=1;' to base64 so I can safely embed it in a JSON field.”
Technical details
Endpoint
GEThttps://workspace-x402-paywall.onrender.com/utils/base64?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, serverless base64 encode/decode operation and are operating within a crypto-native or x402-enabled payment flow using USDC on Base or Solana. It is ideal for AI agents that already handle micropayments via x402 and want a utility call without setting up their own encoding library call. Less appropriate if you can perform base64 natively in code without a network call.
Side effects
- Missing or invalid 'op' parameter (not 'encode' or 'decode') returns an error
- Missing 'data' or 'text' field results in a bad request error
- Payment failure or insufficient USDC balance causes a 402 Payment Required response
- Malformed base64 input when decoding may return a decoding error
- Service unavailability on Render free tier may cause timeouts or cold-start delays
