Configure Codex in CCSwitch for GetAPI.ONE

Compatibility boundary

This workflow applies to compatible Codex targets exposed by the third-party CCSwitch application. It does not apply to the official ChatGPT consumer app, whose documented sign-in flow does not provide a field for an arbitrary third-party API provider.

Prerequisites

• A compatible Codex client or integration target already identified in your current CCSwitch release.
• CCSwitch obtained from its project release page and installed according to that project’s current instructions.
• A private, scoped GetAPI.ONE key and a model that explicitly declares the Responses endpoint.
• The ONE base URL https://www.getapi.one/v1. Do not mix it with another service’s key or URL.

• Prepare a key
• Choose a compatible model

1. Add the custom provider

1. Open CCSwitch and select its Codex provider area.
2. Select the add control, then choose Custom configuration. Scroll if the option is below the initial view.
3. Name the provider GetAPI One and optionally enter https://www.getapi.one as its website.
4. Paste the GetAPI.ONE key into the API Key field and https://www.getapi.one/v1 into the API request address field.
5. Replace YOUR_RESPONSES_MODEL with an exact catalog model visible to the key group and explicitly marked for the Responses endpoint, then save.

2. Enable, restart, and confirm the target

1. Return to the provider list and enable GetAPI One.
2. Fully quit and reopen the compatible target so it reloads provider configuration.
3. Confirm the selected provider and model are GetAPI One and the exact catalog model you entered before sending anything.

3. Verify the connection

1. Only after reviewing current pricing, send one minimal message you accept may be billed.
2. Confirm the target receives a valid response.
3. Confirm that a corresponding request or usage record appears in the GetAPI.ONE console.
