Connect Claude Desktop to OpenDunes through its gateway setting, and pay for its models in DA.
Claude Desktop, Anthropic's desktop app, can send its requests to a gateway instead of Anthropic's own service. It speaks the Anthropic Messages API, which OpenDunes carries at /v1/messages — so the app can run on your OpenDunes wallet, billed in DA.
Launch Claude Desktop — no need to sign in. Open Help → Troubleshooting and click Enable Developer Mode. A Developer menu appears.
Click Developer → Configure Third-Party Inference…, set the connection to Gateway, and fill in:
| Field | Value |
|---|---|
| Gateway base URL | https://opendunes.com |
| Gateway API key | your OpenDunes API key, sk-… |
| Gateway auth scheme | bearer |
| Credential kind | Static API key |
Leave any single sign-on fields empty: OpenDunes takes the key, not a sign-in. Click Apply Changes.
Quit Claude Desktop fully and reopen it. On the start screen, choose Continue with Gateway. No Anthropic account is needed.
Every model you pick must be a name OpenDunes sells, such as anthropic/claude-sonnet-5 or ~anthropic/claude-sonnet-latest; any other name answers 404. The names are in the catalogue.
| Symptom | Fix |
|---|---|
| connection errors | the base URL is exactly https://opendunes.com, the scheme bearer, the key an API key (sk-), not a management key |
402 on every message | the wallet is empty or the key's cap is spent — top up at Billing, or raise the cap |
| "Continue with Gateway" missing | apply the settings, then quit and reopen the app, not only its window |
