What is the Social Fetch Web API?

Five REST routes under the Web tag: public keyword search (GET /v1/web/search), URL to markdown (GET /v1/web/markdown), URL to cleaned HTML (GET /v1/web/html), page Q&A (GET /v1/web/ask), and a bounded multi-URL crawl (GET /v1/web/crawl). Authenticate with a Social Fetch API key. Exact parameters and examples live under /docs/api and on this hub's endpoint list.
