## Configure providers in the Control UI

Open **Settings → Models** in the Control UI to add, replace, or remove provider
API keys. The page and `openclaw models auth paste-api-key` use the same credential
writer: key material stays in the auth store, and configured providers reference
the saved profile. Environment-provided keys remain managed by the Gateway
process environment. The page shows credential sources without revealing keys.

Saving a key and refreshing the catalog are separate outcomes. If refresh fails,
the saved key remains; follow the reported recovery step. Removing a stored key
keeps model defaults and provider connection settings. See
[Auth profiles](/cli/models#auth-profiles) for the matching CLI commands.

Provider controls appear as soon as credentials, the model catalog, and configuration are ready. Usage and local costs load independently afterward, so a slow usage response does not block provider settings.

Open **Model Setup** from the page header to inspect detected AI access. When available, it shows the authentication method (API key or account sign-in) and the actual email address reported by the provider or local runtime. API keys and tokens stay hidden.

Use **Test connection** to run a live provider probe and see latency or a categorized authentication, rate-limit, billing, timeout, or response error. A probe makes a real provider request and may consume a small number of tokens. OAuth and token profiles can also be logged out from the provider card.

The **Defaults** card manages the primary model, utility model, first fallback, thinking level, and Fast mode from the configured model catalog. Changes save automatically to the existing `agents.defaults` settings. For the utility model, **Auto** leaves the setting unset and **Disabled** stores an empty string to turn utility routing off.

The fallback selector edits the first model in the ordered fallback chain. Replacing it preserves any later fallbacks already configured; selecting **No fallback model** clears the chain. Use `openclaw models fallbacks` to manage the full ordered list.

## Plugin-owned provider behavior

Most provider-specific logic lives in provider plugins (`registerProvider(...)`) while OpenClaw keeps the generic inference loop. Plugins own onboarding, model catalogs, auth env-var mapping, transport/config normalization, tool-schema cleanup, failover classification, OAuth refresh, usage reporting, thinking/reasoning profiles, and more.

The full list of provider-SDK hooks and bundled-plugin examples lives in [Provider plugins](/plugins/sdk-provider-plugins). A provider that needs a totally custom request executor is a separate, deeper extension surface.

<Note>
Provider-owned runner behavior lives on explicit provider hooks such as replay policy, tool-schema normalization, stream wrapping, and transport/request helpers. The legacy `ProviderPlugin.capabilities` static bag is compatibility-only and is no longer read by shared runner logic.

## API key rotation

<AccordionGroup>
  <Accordion title="Key sources and priority">
    Configure multiple keys via:

    - `OPENCLAW_LIVE_<PROVIDER>_KEY` (single live override, highest priority)
    - `<PROVIDER>_API_KEYS` (comma or semicolon list)
    - `<PROVIDER>_API_KEY` (primary key)
    - `<PROVIDER>_API_KEY_*` (numbered list, e.g. `<PROVIDER>_API_KEY_1`)

    For Google providers, `GOOGLE_API_KEY` is also included as fallback. Key selection order preserves priority and deduplicates values.

  </Accordion>
  <Accordion title="When rotation kicks in">
    - Requests are retried with the next key only on rate-limit responses (for example `429`, `rate_limit`, `quota`, `resource exhausted`, `Too many concurrent requests`, `ThrottlingException`, `concurrency limit reached`, `workers_ai ... quota limit exceeded`, or periodic usage-limit messages).
    - Non-rate-limit failures fail immediately; no key rotation is attempted.
    - When all candidate keys fail, the final error is returned from the last attempt.
