# Introduction

> Structured biopharma pipeline, trial, deal and patent data over a read-only REST API and an MCP server.

Pav tracks drug development programs and the evidence around them: who is
developing what, for which indication, at which phase, in which trials, under
which deals, and protected by which patents. The Pav API serves that data as
JSON. The same data is available to AI agents through the Pav MCP server.

Current program and company counts are available at any time from
[`GET /v1/stats`](/api-reference/stats/dataset-summary-statistics).

## How the data connects

Every dataset joins through Pav ids.

* A **company** (`company_id`) owns **programs** (`id`).
* A **program** lists its linked **clinical trials** (`nct_id`). A trial lists
  the Pav programs and companies linked to it.
* A **deal** lists its party companies; filter deals by `company_id`.
* A **patent family** lists its owner companies; filter patents by
  `company_id`.
* An **FDA record** carries its linked company; filter FDA records by
  `company_id`.
* A **change** records a program's movement and carries its `company_id`.

Resolve a name to an id once, with `GET /v1/companies?q=...`, then reuse the id
across every dataset.

## API at a glance

* Base URL: `https://api.pav.bio`
* All endpoints are `GET` and return JSON.
* Authenticate with a Pav API key: `Authorization: Bearer <api_key>`.
  See [Authentication](/authentication).
* List endpoints return `{ "data": [...], "pagination": {...} }`.
  See [Pagination](/concepts/pagination).
* `q=` runs relevance-ranked search on programs, companies and trials, and
  exact-term matching on deals and patents.
  See [Search and filters](/concepts/search-and-filters).
* 300 requests per minute per key. Errors share one envelope.
  See [Rate limits and errors](/rate-limits).

## Built for

* Competitive landscapes by target, indication or modality.
* Deal screening and comparable-transaction work.
* Patent, exclusivity and loss-of-exclusivity checks.
* Pipeline monitoring and alerting.
* AI agents that answer biopharma questions with sourced data.
