+# CrofAI
+
+> Uses the CrofAI Usage API with a user-provided API key.
+
+## Overview
+
+- **Protocol:** HTTPS (JSON)
+- **Endpoint:** `GET https://crof.ai/usage_api/`
+- **Auth:** `Authorization: Bearer <api_key>`
+- **Data:** credit balance, daily requests remaining
+
+## Authentication
+
+Set the `CROFAI_API_KEY` environment variable:
+
+```bash
+export CROFAI_API_KEY="your-api-key-here"
+```
+
+The key is read from the environment at probe time. Restart OpenUsage after setting it.
+
+## Data Source
+
+Request:
+
+```http
+GET /usage_api/ HTTP/1.1
+Host: crof.ai
+Authorization: Bearer <api_key>
+Accept: application/json
+```
+
+Response:
+
+```json
+{
+  "credits": 12.3456,
+  "usable_requests": 450
+}
+```
+
+| Field | Type | Description |
+|---|---|---|
+| `credits` | number | Available credit balance (USD) |
+| `usable_requests` | number \| null | Requests remaining today (`null` if not on a subscription plan) |
+
+## Output
+
+- **Requests** (overview text line): requests remaining today (e.g., `450 remaining`); hidden when `usable_requests` is null
+- **Credits** (overview text line): formatted dollar balance (e.g., `$12.35`)
+
+## Errors
+
+| Condition | Message |
+|---|---|---|
+| Missing `CROFAI_API_KEY` env var | `No CROFAI_API_KEY found. Set up environment variable first.` |
+| HTTP 401/403 | `API key invalid. Check your CrofAI API key.` |
+| Non-2xx | `Usage request failed (HTTP {status}). Try again later.` |
+| Network failure | `Usage request failed. Check your connection.` |
+| Unparseable or invalid response shape/type | `Usage response invalid. Try again later.` |
