Orbit turns topic-level research behavior into a usable audience. Start with the subjects people are actively researching, narrow the audience with ICP filters, then materialize a run to retrieve people, fill-rate stats, or a CSV export. The dashboard provides a visual workflow for analyzing a site or topics. This API reference covers the same customer-facing Orbit capabilities for programmatic use. Orbit home

​
Choose a task

Find topics

Browse or search the topic inventory and save reusable topic lists.

Build ICP filters

Inspect available filter definitions and build audience rules.

Preview an audience

Validate a config, estimate audience size, and inspect sample rows.

Manage audiences

Create, activate, pause, update, list, or delete saved audiences.

Run an audience

Queue a materialization run and monitor its status.

Retrieve and export results

Read hydrated people, inspect stats, and export completed runs.
Orbit is built for net-new targeting. It helps you find people and accounts that have not visited your site yet but are already showing signs of demand in the market.

What Orbit is

Orbit is Leadpipe’s intent audience API. Use it to find people researching specific B2B or B2C topics, then narrow those audiences with company, role, job title, contactability, geography, and demographic filters. The current workflow is:
  1. Analyze a site, browse topics, or search topics.
  2. Validate or preview an audience config.
  3. Save an audience as draft or active.
  4. Queue a manual run, or let active audiences refresh through scheduled daily runs.
  5. Read run results, run stats, or export CSV from the run ID.
Topic overlap controls how strict the audience should be. A higher overlap means a person must match more of the selected topics, which makes the signal narrower and usually stronger.

Authentication

Authenticated requests can use an x-api-key header.
API keys are scoped to an organization. Create and manage them in Settings > API Keys in the dashboard. Bearer-authenticated requests are also supported for logged-in frontend users. Do not send sk_... API keys as Bearer tokens.

​
Quick start

Follow Build and export an audience for a complete example with validation, a saved audience, a manual run, bounded polling, and export checks. You need an organization API key, audience access, curl, and jq. Select real topic IDs from topic discovery; sample topic IDs are not recommendations for your audience. A preview estimates size and returns masked samples. Creating an audience saves its definition; it does not produce contacts. A completed run provides the result snapshot you can page through or export.

Authentication and limits

See Authentication and errors for API-key setup and endpoint-specific error handling. Public discovery is not one universal rate-limit bucket: Find topics explains the differences.
Integration, destination, and delivery operations currently have conflicting authentication descriptions and security declarations in the hosted spec. Confirm access with Leadpipe before relying on API keys for these operations. See the access note.
The endpoint reference is generated from the hosted Orbit OpenAPI specification.
