Analytics

Overview

The analytics endpoint returns aggregated usage statistics for your gateway — request volume, success/failure rates, and breakdowns by provider, model, project, and day. Aggregates are stored in Cloudflare D1. It exposes operational load data, so all requests require a valid GATEWAY_API_KEY Bearer token; without one the gateway returns 401.

Endpoint: GET /v1/analytics

Authentication: Required (GATEWAY_API_KEY)

Request

GET https://your-gateway.workers.dev/v1/analytics?project_id=proj_abc123

Query Parameters

Parameter	Type	Required	Description
project_id	string	No	Filter analytics to a single project. Omit for all-project totals.
