**Legacy API key not supported.** Keys that begin `sk_live_` predate scopes and test mode. They keep working where they worked before, but the v1 API accepts only scoped keys (`rai_test_` and `rai_live_`).

## What it means

The API returns HTTP 401 with `error.code` set to `legacy_api_key_not_supported`. The default message is: "Legacy API keys cannot be used with the v1 API. Create a scoped key in the console."

## Common causes

- An `sk_live_` key was sent to the v1 API.

## How to identify it

Check the response status (`401`) and `error.code` (`legacy_api_key_not_supported`). Branch on `error.code`, not on the message text: messages can be reworded, codes do not change within v1. Log `error.request_id` (also sent as the `X-Request-Id` header) so support can find the request.

## How to fix it

- Create a scoped key in the console under API & Developers and use it instead.

## Retry guidance

Sending the request unchanged fails the same way. Fix the cause first (see How to fix it), then send it again.

## Did anything happen?

This request was refused before any call was placed and before anything was charged.

## Idempotency

Nothing was done and nothing was stored (under an Idempotency-Key, if you sent one), so the request can be sent again, with the same key if you used one, once the cause is fixed.

## Who can fix it

A workspace administrator usually has to act, in the RelationsAI console.

## When to contact support

If the error persists after the steps above, contact [support@relationsai.com](mailto:support@relationsai.com). See [Support](/resources/support) for what to include (the `request_id`, the time in UTC, the operation, and whether you used a test or live key) and what never to send (API keys, Authorization headers, webhook signing secrets, recording links, transcripts or customer data).
