# Unified payment history

`GET /admin/mcp/billing/users/{userId}/payments`

Charges with their refund state, newest first. Each row carries a composite `<provider>:<id>` id — the only id the refund endpoint accepts. Providers served elsewhere return an empty page with `supported: false` rather than an error.

## Path parameters

- `userId` string, required

## Query parameters

- `page` number
- `pageSize` number

## Headers

- `x-mcp-api-key` string, required

## Response `200`
