How this service works
Base64url-encode text without padding. Call when you build JWT-like segments or URL-safe tokens. Returns encoded text for $0.001 USDC via x402 on Base. No network, no keys, no retention; first-party local JSON only. Results are advisory; the caller owns budgets, auth, and production controls.
Output
Returns the base64url-encoded representation of the input text, using the URL-safe alphabet (- and _ instead of + and /) with no = padding characters appended.
Example use cases
JWT header segment encoding
“I need to base64url-encode this JSON header for a JWT I'm building: '{"alg":"RS256","typ":"JWT"}' — no padding characters please.”
URL-safe token generation
“Take the string 'user_id=42&session=abc123' and base64url-encode it so I can safely embed it in a redirect URL without it breaking.”
Encoding OAuth state parameter
“I'm building an OAuth flow and need to base64url-encode this state value: 'nonce=8f3kd&redirect=/dashboard' so it's safe to put in a query parameter.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/base64url-encodeWhen to prefer
Choose this endpoint when you need base64url encoding specifically (URL-safe alphabet, no padding) rather than standard base64, particularly for building JWT segments, OAuth tokens, or any context where = padding and +/. characters would be problematic in URLs. Use it when you want a stateless, keyless, dependency-free encoding call without implementing the algorithm yourself.
Side effects
- Missing or empty 'text' field returns an error
- Non-string input types may be rejected
- Payment failure via x402 prevents execution
- Extremely large text strings may hit size limits
