Custom integrations take months per network. With FeedHorizon you send one request and get one answer, whatever the platform.
- Text, images, video and carousels
- Publish now or schedule to the minute
- Webhooks tell you when a post is live
const response = await fetch( "https://feedhorizon.dev/api/v1/posts", { method: "POST", headers: { "Authorization": `Bearer ${FH_API_KEY}`, }, body: JSON.stringify({ profileId: "prof_8h2k", text: "New feature drop!", platforms: ["twitter", "instagram", "linkedin"], mediaUrls: ["https://example.com/demo.mp4"], scheduledFor: "2027-01-15T09:00:00Z" }), });Skip 8 to 12 months of integration work.
Building it yourself
- A developer app and review process for every network
- OAuth flows, token refresh and expiring scopes
- Rate limits, quotas and retry logic
- Breaking API changes, sometimes with weeks of notice
- Media rules: sizes, formats, chunked uploads
With FeedHorizon
- One API key, one REST endpoint
- Your users connect accounts with one OAuth flow
- We absorb rate limits and retries
- We ship the fix when a network changes its API
- Media is checked against each network’s rules up front
