+# Anthropic (Claude)
+
+Anthropic builds the **Claude** model family and provides access via an API.
+In OpenClaw you can authenticate with an API key or a **setup-token**.
+
+## Option A: Anthropic API key
+
+**Best for:** standard API access and usage-based billing.
+Create your API key in the Anthropic Console.
+
+### CLI setup
+
+```bash
+openclaw onboard
+# choose: Anthropic API key
+
+# or non-interactive
+openclaw onboard --anthropic-api-key "$ANTHROPIC_API_KEY"
+```
+
+### Config snippet
+
+```json5
+{
+  env: { ANTHROPIC_API_KEY: "sk-ant-..." },
+  agents: { defaults: { model: { primary: "anthropic/claude-opus-4-5" } } },
+}
+```
+
+## Prompt caching (Anthropic API)
+
+OpenClaw supports Anthropic's prompt caching feature. This is **API-only**; subscription auth does not honor cache settings.
+
+### Configuration
+
+Use the `cacheRetention` parameter in your model config:
+
+| Value   | Cache Duration | Description                         |
+| ------- | -------------- | ----------------------------------- |
+| `none`  | No caching     | Disable prompt caching              |
+| `short` | 5 minutes      | Default for API Key auth            |
+| `long`  | 1 hour         | Extended cache (requires beta flag) |
+
+```json5
+{
+  agents: {
+    defaults: {
+      models: {
+        "anthropic/claude-opus-4-5": {
+          params: { cacheRetention: "long" },
+        },
+      },
+    },
+  },
+}
+```
+
+### Defaults
+
+When using Anthropic API Key authentication, OpenClaw automatically applies `cacheRetention: "short"` (5-minute cache) for all Anthropic models. You can override this by explicitly setting `cacheRetention` in your config.
+
+### Legacy parameter
+
+The older `cacheControlTtl` parameter is still supported for backwards compatibility:
+
+* `"5m"` maps to `short`
+* `"1h"` maps to `long`
+
+We recommend migrating to the new `cacheRetention` parameter.
+
+OpenClaw includes the `extended-cache-ttl-2025-04-11` beta flag for Anthropic API
+requests; keep it if you override provider headers (see [/gateway/configuration](/gateway/configuration)).
+
+## Option B: Claude setup-token
+
+**Best for:** using your Claude subscription.
+
+### Where to get a setup-token
+
+Setup-tokens are created by the **Claude Code CLI**, not the Anthropic Console. You can run this on **any machine**:
+
+```bash
+claude setup-token
+```
+
+Paste the token into OpenClaw (wizard: **Anthropic token (paste setup-token)**), or run it on the gateway host:
+
+```bash
+openclaw models auth setup-token --provider anthropic
+```
+
+If you generated the token on a different machine, paste it:
+
+```bash
+openclaw models auth paste-token --provider anthropic
+```
+
+### CLI setup
+
+```bash
+# Paste a setup-token during onboarding
+openclaw onboard --auth-choice setup-token
+```
+
+### Config snippet
+
+```json5
+{
+  agents: { defaults: { model: { primary: "anthropic/claude-opus-4-5" } } },
+}
+```
+
+## Notes
+
+* Generate the setup-token with `claude setup-token` and paste it, or run `openclaw models auth setup-token` on the gateway host.
+* If you see "OAuth token refresh failed ..." on a Claude subscription, re-auth with a setup-token. See [/gateway/troubleshooting#oauth-token-refresh-failed-anthropic-claude-subscription](/gateway/troubleshooting#oauth-token-refresh-failed-anthropic-claude-subscription).
+* Auth details + reuse rules are in [/concepts/oauth](/concepts/oauth).
+
+## Troubleshooting
+
+**401 errors / token suddenly invalid**
+
+* Claude subscription auth can expire or be revoked. Re-run `claude setup-token`
+  and paste it into the **gateway host**.
+* If the Claude CLI login lives on a different machine, use
+  `openclaw models auth paste-token --provider anthropic` on the gateway host.
+
+**No API key found for provider "anthropic"**
+
+* Auth is **per agent**. New agents don't inherit the main agent's keys.
+* Re-run onboarding for that agent, or paste a setup-token / API key on the
+  gateway host, then verify with `openclaw models status`.
+
+**No credentials found for profile `anthropic:default`**
+
+* Run `openclaw models status` to see which auth profile is active.
+* Re-run onboarding, or paste a setup-token / API key for that profile.
+
+**No available auth profile (all in cooldown/unavailable)**
+
+* Check `openclaw models status --json` for `auth.unusableProfiles`.
+* Add another Anthropic profile or wait for cooldown.
