}Publishing and scheduling tools push content out. Captapi is the read side — it pulls clean, structured data back in. Drop it in next to your scheduler, social CRM, analytics dashboard, or AI agent. No OAuth, no per-platform SDKs.
A focused toolkit for builders.
From scrappy MVPs to enterprise data pipelines.
Pay only for what you use — cached results are always free.
Perfect for testing
For side projects
For growing products
For data pipelines
No. One Captapi key gives you access to all 33 platforms. We handle authentication, proxies, rate limits, and retries for you.
Official APIs are restrictive (rate limits, OAuth flows, deprecated endpoints, no transcript support for Reels/TikToks). Captapi works on public data with one consistent REST interface — no app review process, no quotas to negotiate.
Yes. On the billing page you can set one or more credit alerts — for example 80% and 90% of the balance you had when you saved each threshold, or a remaining-credit floor (for example 5). After each API request we check the balance and email you from alert@captapi.com. The default address is the one you signed up with; you can change it in the alert modal.
Each endpoint has its own credit cost (see the docs) — simple lookups are often 1–4 credits; many list/search/comment endpoints are a flat 2 credits per call, while some list endpoints still scale with results. Pass cache=true for a free 24h cache hit; default is always fresh.
You'll get a 422 with a clear error message. We don't charge credits for empty results — only for successful data extraction.
Yes. All paid plans are monthly and cancellable with one click in the dashboard. No long-term contracts.
Captapi only extracts publicly accessible data and is intended for compliant business use. You are responsible for how you process and store the data within your jurisdiction.
No. Captapi is a read-only data API — it extracts transcripts, comments, metadata, search results, profiles, ad intelligence, commerce data, and engagement metrics from public content. It pairs perfectly with publishing and scheduling tools: use them to post, and use Captapi as the data layer that measures and analyzes performance across platforms.
Yes. The cross-platform analytics endpoint detects the platform from the URL and returns the same normalized metrics object — views, likes, comments, shares, saves, interactions, and engagementRate — so you do not have to special-case each network. The schema is stable; unavailable values are null (for example YouTube has no public share or save counts). engagementRate is interactions / views when both are available.
Sign up, copy your API key, make your first call — no credit card, no demos.
