How this service works
Pay $0.01-0.02 USDC per call on Base via x402
Output
Returns a JSON object confirming the tip was received, including the amount paid (e.g. '1.00 USDC'), a boolean 'thanks' field set to true, a thank-you message string, and the network identifier (eip155:8453 for Base mainnet).
Example use cases
Tipping a web3 API service
“Send a 1 USDC tip to this x402 service on Base and include the note 'thanks for the keyword ideas' — let me know when it's confirmed.”
Testing x402 payment flow
“Make a test micropayment tip of 1 USDC via x402 on the Base network to verify the payment endpoint is working correctly.”
Automated pay-per-call workflow
“Set up a payment to send a 1 USDC tip via x402 on Base each time I use the SEO keyword API, and log the confirmation messages.”
Technical details
Endpoint
GEThttps://x402-seo-api.restockalarm.workers.dev/v1/tip?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to send a micropayment tip specifically via the x402 protocol on the Base blockchain and receive a payment confirmation receipt. It is appropriate when building pay-per-call web3 workflows or testing x402 payment flows rather than querying for actual SEO keyword data.
Side effects
- Insufficient USDC balance causes payment failure
- x402 payment header missing or malformed results in 402 response
- Wrong network (non-Base) causes transaction rejection
- Note field exceeds 200 characters triggers validation error
- Network congestion delays confirmation
