+# packages/api-server
+
+## Scope
+
+- This package is the HTTP transport layer over `@marketplace-scrapers/core`.
+- Route files in `src/routes/*.ts` should parse inputs, call core, and map responses/errors.
+
+## Keep Thin
+
+- Do not move scraping, parsing, selector, or cookie-loading logic into routes.
+- If route code starts branching on marketplace behavior, push that behavior back into `packages/core`.
+
+## Route Conventions
+
+- Register new routes in `src/index.ts`.
+- Follow existing input precedence where present: `query` header first, then `q` search param.
+- Preserve existing response shape style: `Response.json(...)`, `400` for bad input/errors, `404` for empty result sets, `200` for success.
+- Keep query parameter names aligned with the MCP server because MCP builds URLs against these endpoints.
+
+## Verify
+
+- `bun run --cwd packages/api-server build`
+- `bun run ci`
