# API Overview

> Base URL, authentication, and conventions shared by every endpoint

All endpoints live under a single base URL:

```
https://api.compliapi.com/api/v1
```

Everything is a `GET`. Metered endpoints (screening, VPN, geolocation) require a bearer [API token](/authentication) — or, with no token at all, [x402 pay-per-request](/payments). The public data feeds (`/stats`, `/delisted`, `/screen/lists`) are unauthenticated and free.

## Requests and quota

Each metered request costs one credit against your organization's monthly quota, regardless of how many lists match. Over quota you get `402` with the option to pay per request or upgrade; burst limits return `429` with a `Retry-After` header. Every request is written to your audit trail.

## Response conventions

Screening responses share [one envelope](/api/screen): `sanctioned` is true only for government **sanctions**-list hits, `flagged` is true for any hit (sanctions, crime-intelligence, or risk-exposure), and every match names the list that produced it. All timestamps are UTC ISO-8601.

The same endpoints are also exposed as [MCP tools](/mcp) for AI agents.
