How this service works
Web search built for AI agents. Search the live web, pull recent news, and read any page as clean markdown — pay per call, free tier to start.
Output
Returns the base64-encoded or base64-decoded result of the input text, with optional URL-safe character substitution (using - and _ instead of + and /).
Example use cases
Example prompt
“Encode the text 'Hello, World!' to base64 using URL-safe encoding.”
Technical details
Endpoint
GEThttps://superhighway.walls.sh/base64?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a simple, pay-per-call base64 encode or decode operation without setting up a local library or utility, especially in agent workflows where a lightweight remote call is more convenient than bundling encoding logic.
Side effects
- Missing required 'text' parameter returns an error
- Invalid base64 string passed to decode operation returns a decoding error
- Malformed urlsafe flag value may cause unexpected behavior
- Payment failure (x402) if USDC balance is insufficient
