A member creates a token for one billing account under *API tokens* in the panel; it can do what both the token's permissions and the member's own permissions allow, the same as the panel. Send it as `Authorization: Bearer pgapi_...`. Each token may make 120 requests a minute, of which 30 change something; a `429` response says when to try again (`Retry-After`). Ids are the ULIDs the API returns; amounts are decimal strings next to their currency; lists are newest first and paged with `cursor` (`meta.next_cursor`). Messages are in English, or Danish with `Accept-Language: da`. The same tokens work with the MCP server at `/mcp` for AI assistants. servers: - url: https://console.perfgrid.com/api/v1 security: - http: [] tags: - name: Account - name: Invoices - name: Services - name: Domains - name: Support paths: /services/{service}/changes/quote: post: tags: - Services summary: Quote a change description: |- What the change would cost and when it would take effect.
