Common questions about connecting and running Webhook Tester API.
What is x402 micropayment and how does it work with this server?
x402 is a protocol for metered API access. This server uses x402 to enable pay-per-request webhook testing. Check the hosted endpoint documentation for current pricing and payment setup.
How do I connect this MCP server to my Claude session?
Use the SSE transport endpoint: https://webhook-tester-x402-production.up.railway.app/mcp. Configure your MCP client to connect via Server-Sent Events and authenticate with your x402 payment method.
Can I test webhooks from any URL or are there restrictions?
The server accepts webhook endpoints you provide and sends test requests to measure latency and validate responses. Refer to the hosted endpoint documentation for any URL restrictions or rate limits.
What response data does the webhook tester return?
The server returns response latency measurements, HTTP status codes, response bodies, and validation results. Exact schema and available metrics are documented in the endpoint's API reference.
Is there a free tier or trial for webhook testing?
The server uses x402 micropayments for access. Check the hosted endpoint or contact the maintainer for pricing details, free tier availability, or trial options.
