Opportunity Market API

Every endpoint below is public, read-only, and unauthenticated — the same data the site itself renders, as JSON. Responses are shaped { data: … } on success or { error: … } with a non-2xx status on failure. There is no API key: results are cached briefly server-side (scores move on an hourly cycle) and requests are otherwise unlimited, so please be a reasonable neighbour — cache on your side too if you're polling.
