Claude Desktop

Claude Desktop can talk to third-party gateways that speak the Anthropic Messages API. ApiGo exposes that surface at https://api.apigo.ai, so you can keep Claude Desktop’s native protocol while billing and logging through ApiGo.

Prerequisites

Configuration

1. Enable Developer Mode

Launch Claude Desktop (you do not need an Anthropic sign-in). Open Help → Troubleshooting → Enable Developer Mode. A Developer menu appears in the menu bar.

2. Open third-party inference

Choose Developer → Configure Third-Party Inference….

3. Enter Gateway credentials

Set the connection type to Gateway and fill in:

Field Value
Gateway base URL https://api.apigo.ai
Gateway API key your sk-apigo-... key
Gateway auth scheme bearer

Leave OIDC / SSO IdP fields blank. ApiGo authenticates with a static API key.

Click Apply locally.

4. Restart and continue with Gateway

Fully quit Claude Desktop and reopen it. On the start screen, choose Continue with Gateway (local configuration).

5. Pick a model

Use the model picker with IDs available on your ApiGo workspace. Browse slugs in the Model Catalog.

For a terminal workflow, see Claude Code.

Troubleshooting

Symptom Fix
Connection errors Base URL must be exactly https://api.apigo.ai (no /v1 suffix); auth scheme bearer
“Continue with Gateway” missing Apply locally, then fully quit and reopen (not only close the window)
No models Confirm workspace balance and that the key is active
