Questions & Answers

As answered by people managing Sejda and InvisibleAPI.

What makes your product unique?

InvisibleAPI's answer:

InvisibleAPI is built as developer infrastructure rather than a bloated social media management dashboard. Key differentiators include:

  • Guaranteed idempotency: passing a clientRequestId ensures that retried API calls never double-post.
  • Native MCP server: ships with a live Model Context Protocol server so AI agents in Claude, Cursor, and custom frameworks can publish autonomously.
  • Complete token management: handles OAuth provider connections, encrypted token storage at rest, and automated token refreshes.
  • Preflight validation and categorized errors: requests are validated against platform rules before dispatch, and errors are categorized as caller error, transient failure, or user action required.
  • 15+ years of production experience: built by a team, who have operated production social media infrastructure at scale since 2011.

Why should a person choose your product over its competitors?

InvisibleAPI's answer:

Most social API wrappers merely forward requests and forward provider failures. When third-party platform APIs break or change without notice, downstream products break.

InvisibleAPI acts as true infrastructure. It absorbs platform-specific quirks, rate limits, token lifecycles, and delivery tracking behind a single, consistent API. You get:

  • Resilient asynchronous job processing with Temporal, rather than brittle synchronous calls.
  • Actionable error classifications so your code knows immediately whether to retry, alert the user, or fix payload data.
  • No feature gating: every account gets access to publishing, the MCP server, and team management without arbitrary tier limits.
  • Instagram and X are live today, with TikTok, Facebook, LinkedIn, and YouTube rolling out on the exact same endpoint shape.

How would you describe the primary audience of your product?

InvisibleAPI's answer:

The primary audience is developers and engineering teams building social publishing features directly into their own applications.

InvisibleAPI is built specifically for:

  • Product teams: SaaS founders and engineering teams shipping in-app social publishing without building custom platform integrations.

  • AI agent developers: Builders using Claude, Cursor, or autonomous agent frameworks who need an MCP-native tool to publish and read social data.

  • Agencies: Teams managing multiple client social accounts across isolated multi-tenant organizations with role-based access.

What's the story behind your product?

InvisibleAPI's answer:

The team behind invisibleAPI has operated social media infrastructure in production for over 15 years. Over that time, product teams repeatedly asked the same question: "We love what your platform does, but we need the capability inside our own application."

Every team that tried building it internally hit the identical wall: juggling multiple platform OAuth flows, silent token expirations, sudden breaking changes, and conflicting rate limits.

We had already solved these operational problems in production. We created InvisibleAPI to expose that battle-tested plumbing as a clean, unified API so developers and AI agents never have to rebuild it from scratch.
