Instagram Channel Details API
Instagram profile stats — fixed key set (null fillers), fbid, bioLinks, isBusinessAccount, approx flags.
GET request to /v1/instagram/channel-details that responds with clean JSON and costs 1 credit. Pass cache=true for a free 24h cache hit; default is always fresh. Start with 100 free credits — no credit card.What is the Instagram Channel Details API?
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.
What you get
- Display name, handle or URL, bio, and avatar when available
- Follower / subscriber and content counts
- Verification status and external links when exposed
- Structured JSON ready for enrichment and dashboards
