Base64 Encode/Decode API

Choose this endpoint when you need a quick, reliable Base64 encode/decode operation as part of an automated agent workflow and are already integrated with the x402 micropayment protocol on Base. It is particularly useful when you need a hosted, stateless conversion without running your own compute, and when $0.001 USDC per call is acceptable. Prefer a local library instead if you need to avoid network latency or payment overhead for high-volume encoding tasks.

• Missing required 'input' field returns a 400-level error
• Invalid body type (not json/form-data/text) causes request rejection
• Malformed Base64 input during decode may return an error or garbled output
• Network timeout or Railway platform downtime returns 5xx
• Insufficient USDC balance causes x402 payment failure, blocking the request
