How this service works
Real-time airfare intelligence for AI travel-booking agents: flight price-drop prediction, fare-fraud and deal-legitimacy verification, and verified booking links for any route and date. Pay-per-call in USDC on Base. No API key.
Output
Returns a JSON object with the mode used, the character count of the input in bytes, and the output string (Base64-encoded or decoded plaintext depending on mode selected).
Example use cases
Encode API credential for header
“Base64-encode the string 'myusername:mypassword' so I can use it in a Basic Auth header.”
Decode a JWT payload segment
“Decode this base64 string for me so I can read what's inside it: 'eyJ1c2VyIjoiYWxpY2UiLCJyb2xlIjoiYWRtaW4ifQ=='”
URL-safe base64 for web token
“Encode the string 'user_id=42&session=abc123' in URL-safe base64 so it's safe to put in a query parameter.”
Technical details
Endpoint
POSThttps://tripguard-fare-intel.onrender.com/base64?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a simple, stateless Base64 encode or decode operation without setting up a local library, especially in agent pipelines that already use x402/USDC micropayments on Base. The URL-safe flag makes it suitable for generating web-safe tokens. Note: the branding ('TripGuard Fare Intelligence') and pricing description are inconsistent with the actual /base64 endpoint functionality — this endpoint performs Base64 conversion only.
Side effects
- Input string exceeds 65536 character limit — request rejected
- Invalid base64 input during decode — may return error or garbled output
- Missing or invalid mode enum value — request fails validation
- Non-UTF-8 binary input may not round-trip cleanly through the string field
