Google Shopping search via micropayment-protected API — pay per request, no signup required.
What it does
StableEnrich's Google Shopping search endpoint (`/api/serper/shopping`) provides programmatic access to Google Shopping results through a pay-per-request micropayment model. It is part of the StableEnrich platform, which unifies multiple research and enrichment data sources behind a single interface secured by micropayments (USDC on Base, Solana, or Tempo). No API keys or subscriptions are needed — payment itself serves as authentication.
The endpoint is designed for AI agents and automated workflows that need to query product listings, prices, and merchant information from Google Shopping. It is accessed via the AgentCash MCP server or CLI, which handles payment negotiation and signing automatically. Based on the StableEnrich pricing page, web search endpoints are priced at $0.015 per request, though the exact price for the shopping-specific endpoint is not explicitly confirmed and may differ.
The probe did not return a 402 challenge on HEAD or GET, so the endpoint may require a POST method or may not have been reachable at probe time. No OpenAPI schema or detailed parameter documentation was captured for this specific route. Users should consult the StableEnrich llms.txt file or use the `discover_api_endpoints` / `check_endpoint_schema` AgentCash tools for current schema and pricing details.
