Instagram Channel Details API
Instagram profile stats — fixed key set (null fillers), fbid, bioLinks, isBusinessAccount, approx flags.
Send a profile URL or @handle and get clean JSON with a fixed key set on every profile (absent → null, never a missing key): platform, url, id, fbid, username, displayName, bio, bioLinks, followers, following, postCount, verified, avatar, imageExpiresAt, externalUrl, isPrivate, isBusinessAccount, followersIsApproximate, followingIsApproximate, postCountIsApproximate, fetchedAt. Twin aliases handle/name/profileImage and the duplicate profileImageHd key are not emitted — avatar is the single best profile-pic URL (CDN size token upgraded when Instagram only ships s150x150). Approx flags are derived from the source (true when a count came from a K/M/B display string such as og:description "32K"). Flat 1 credit. Cold path races WPI/GraphQL/HTML; hard cap 110s → 502, 0 credits. Pass cache / cacheMaxAge for the profile trust layer.

Query parameters
Instagram profile URL, @handle, or username, e.g. https://instagram.com/username/. The URL platform must match this endpoint's platform. Do not pass cross-platform URLs, e.g. YouTube to TikTok, Instagram to Facebook, LinkedIn to X/Twitter, or Pinterest to Rumble.
Set true to serve from the response cache (default TTL). Default false — always fetch fresh. Prefer cacheMaxAge when you need 1d–30d freshness control.
Max age of a cached response: 1d, 3d, 7d, 14d, or 30d. When set, enables caching with that TTL.
