Pricing, limits, and integration
The API is not a separately-priced product, it comes with the SaaS subscription, so its cost is just your plan: €79/mo Growth, €279/mo Pro, or from €499/mo Enterprise (each about 20% cheaper billed annually). There is no free tier, but a 14-day trial with no card lets you exercise the API before paying. Because access is identical across tiers, the practical limit is not the API itself but the plan's prompt allowance (25 / 100 / 200+) and the monthly Insight credit pool (150 / 600 / 1,500).
On limits, know what is not published. Omnia documents that rate limiting exists but does not state the numbers, so treat sustained high-frequency polling as something to test rather than assume. There are no webhooks, so there is no push path; everything is a pull against REST or MCP. And there is no official SDK, so you are writing HTTP calls directly against app.useomnia.com/api/v1 with a Bearer token.
How much does the Omnia API actually cost?
Omnia publishes an API, but per-tier gating wasn't extracted automatically.
- Most likely scenario: API access is either included in all paid plans, or it's gated to higher tiers and we need to verify on the live docs page.
- Until verified, treat the question "which plan unlocks the API" as open. Don't budget on the assumption it's free with the cheapest paid plan.

Which AI clients can read Omnia data?
Not every AI assistant supports MCP natively. Here's the per-client picture for Omnia specifically.
| Client | Support | Notes |
|---|---|---|
| Claude Code | Native MCP | Vendor documents: claude mcp add --transport http omnia https://app.useomnia.com/mcp |
| Claude (Desktop/Web) | Native MCP | OAuth connector, one connection for both data and discovery tools. |
| ChatGPT | Native MCP | Listed as a supported client. |
| Cursor | Native MCP | JSON config with the app.useomnia.com/mcp URL. |
Omnia also has an MCP server
If you're wiring Omnia into Claude / Cursor / Codex, the MCP server is usually less code than the REST API.

Glue Omnia into your daily workflow
- Pull a digest of ranking changes into your morning Slack
- Trigger a one-off backfill when something looks off
- Pipe data into your own SQLite for ad-hoc queries
Sell Omnia reporting at scale
- White-label Omnia data into client-branded dashboards
- Run scheduled multi-account reports without logging into the Omnia UI
- Cross-reference with the rest of the client's stack (CRM, analytics, ad spend)
Production pipelines for Omnia
- Real-time sync into your warehouse on a cron
- Custom alerts the dashboard's built-in alerting can't express
- Backfill + idempotency handling for Omnia data older than the dashboard exposes
Limits and gotchas
- No OpenAPI spec — you write typed clients by hand or use a third-party generator on the docs HTML.
- No official SDK detected. Plan on hitting the API directly with your HTTP client of choice.
- Rate limits: always read the docs page before scaling — the published limit is usually lower than the practical one and overages can be expensive.
Agent-readiness verdict
A clean, conventional REST API whose best feature is simply being available at the entry price. You can script exports and wire Omnia's visibility data into your own reporting on the €79 Growth plan. The honest gaps are the young-product ones: no official SDK (you call REST by hand), no webhooks (you poll), no published OpenAPI spec or rate-limit numbers. For a reporting integration that is fine; for anything event-driven, plan around the polling.
Strong agent fit for a GEO tool, and unusually so at the entry price. Omnia exposes an official OAuth MCP server (app.useomnia.com/mcp) and a Bearer-authenticated REST API (app.useomnia.com/api/v1), and BOTH are included on every plan from the €79 Growth tier rather than gated to Enterprise. The MCP gives an agent one connection to both data tools (share of voice, citations, sentiment, topics, prompts, insights, trends across ChatGPT, Perplexity, Google AI Overviews, Claude, Copilot and Gemini) and discovery tools that search Omnia's own API docs. Documented for Claude Code, Claude Desktop, Cursor, VS Code and ChatGPT, with machine-readable llms.txt. It stays short of a top score because it is read-oriented (pull visibility data in, no write/action surface over MCP), young, and ships no official SDK, no webhooks and no published rate limits or OpenAPI spec.
