# Cloudflare Sandbox

This reference is generated from the same provider capability model used by every Wildflower SDK. It describes the portable create surface and the non-secret connection context kept separate from provider credentials.

- **Contract value:** **`cloudflare`**
- **Create input:** **No provider-specific create options**
- **Connection fields:** **1**

## Create options

Wildflower rejects provider-specific create options for this adapter instead of silently ignoring them.

## Runtime behavior

These capability facts come from the same generator-owned model used by the provider catalog and SDK documentation.

- **Image selection:** **fixed**
- **Timeout:** **provider managed**
- **Output streams:** **separate**
- **Working directory:** **Supported**
- **Environment variables:** **Not supported**
- **Persistent resume:** **Supported**
- **Explicit stop:** **Not supported**
- **Snapshots / restore:** **Not supported**
- **Delete:** **Supported**

## Connection context

These values identify provider-side workspace or bridge context. They are not credentials and remain separate from the provider API key.

| Field | Inline header |
| --- | --- |
| `bridgeUrl` | `X-Provider-Bridge-Url` |

> **Credentials never enter the create body**
>
> Connect the provider once for the project, or send a typed inline credential override. Wildflower keeps credentials in authentication headers and never serializes them into sandbox JSON.

## Usage, cost, and latency evidence

- **Billing signal:** **provider analytics api**
- **Wildflower integration:** **additional credentials required**
- **Provider granularity:** **instance**
- **Expected lag:** **analytics pipeline delay**
- **Provider-reported cost:** **Unavailable**
- **Live credential proof:** **Not verified**

> **Cloudflare Sandbox provider cost is not available**
>
> Cloudflare exposes per-instance usage metrics, but the current bridge contract does not expose the required analytics identity or credential.
>
> [Review the official provider signal source](https://developers.cloudflare.com/analytics/graphql-api/tutorials/querying-container-metrics/). A normalized list-price estimate remains separate from provider reporting and invoice reconciliation.
