> ## Agent Instructions
> Base URL: https://api.social-api.ai/v1. Send your API key in the Authorization header: Authorization: Bearer <your API key>.
> Every error response from /v1 is JSON: { "error": { "code", "message", "meta" (optional) }, "request_id" }. Branch on error.code; use error.message only for logs.
> A 429 response carries a Retry-After header, in seconds, when the limit has a known wait.
> Paginated list endpoints return next_cursor, at the top level or inside pagination (see /guides/pagination). Pass it as the cursor query parameter to get the next page. An absent or empty next_cursor means you have the last page.
> Treat every ID as an opaque string: do not parse it or assume a format.
> Support differs by platform and by operation. Check /platforms/overview before assuming an operation works on a platform. An unsupported operation returns 501 with error.code resource.not_supported.

# Get daily Facebook Page insights

> Returns one point per day for one Page of a connected Facebook account: followers at the end of the day, plus that day's views, reach and post engagements. Days with no data are omitted. Same permission errors as the Page insights summary.
