How this service works
Quality-scored paid utility APIs for AI agents over x402 on Base USDC.
Output
A JSON object containing a 'result' key with a 'base64' field holding the Base64-encoded string representation of the input text (e.g. {"result":{"base64":"aGVsbG8="}}).
Example use cases
Encode API credentials for auth header
“I need to base64 encode my username and password combined as 'myuser:mypassword' so I can use it in a Basic Auth header.”
Encode JSON payload for embedding
“Can you base64 encode this JSON string so I can embed it safely in a URL parameter: '{"userId":"abc123","role":"admin"}'?”
Encode large text block for transmission
“I have a large text document I need to encode as base64 before sending it through our message queue — can you encode this content for me: 'Invoice #4521: Total due $1,200.00. Payment terms: Net 30.'”

Endpoint
POSThttps://agent-utility-network.frosty-sound-4560.workers.dev/v1/paid/base64-encodeWhen to prefer
Choose this endpoint when your agent workflow requires a metered, pay-per-call Base64 encoding step with guaranteed quality scoring and x402/USDC payment integration on Base. It is especially suitable for AI agent pipelines on Coinbase's ecosystem that already handle x402 micropayments and need a reliable, on-demand encoding utility without managing local libraries.
Side effects

- Payment failure via x402/USDC — 402 Payment Required returned
- Malformed request body missing 'text' field — validation error
- Network timeout or worker unavailability — 5xx error
- Empty string input may return empty base64 result
