News & Shopping Search with Serper

STOP — Read before making any API call. enrichx402.com endpoints are not the same as each provider's native API. All paths use the format https://enrichx402.com/api/{provider}/{action}. You MUST either:

1. Copy exact URLs from the Quick Reference table below, OR
2. Run x402.discover_api_endpoints(url="https://enrichx402.com") to get the correct paths

Guessing paths will fail with 405 errors (wrong path) or 404 errors (missing /api/ prefix).

Access Google News and Google Shopping through x402-protected endpoints.

Setup

See rules/getting-started.md for installation and wallet setup.
