## Credits Overview

At the core, all APIs are charged at **1 credit per call**. This can vary depending on internal costs and how much data is being processed.

Example list of exclusions to this rule:

| API Name | Cost                             |
| -------- | -------------------------------- |
| Search   | 1 credit per search type (max 3) |

## Websocket Pricing

Websockets are billed **per message**, with rates that vary by room. Opening a new connection places a 1 credit hold that is charged even if you disconnect immediately. Because credits are fractional, any usage is rounded up to the nearest whole credit at the end of the billing period.

See the [Websocket Pricing](/websockets/pricing) page for the full per-room rate card and example calculations.
