Changes to the [Agent API](https://docs.vigilbase.com/tools/developers/agent-api), newest first.

## 3 November 2026: older URLs retire on 1 February 2027

The older Agent API URLs stop working on **Monday 1 February 2027 at 00:00 UTC**:

- `https://vigilbase.com/api/v1/agent/tools` and `https://vigilbase.com/api/v1/agent/tools/{toolName}/execute`;
- `https://vigilbase.com/api/agent/tools` and `https://vigilbase.com/api/agent/tools/{toolName}/execute`. These were previously announced for 1 September 2027.

Use `https://api.vigilbase.com/tools/v1/agent/tools` instead. Paths, bodies and API keys are the same. Until the date, the older URLs answer as before and send `Sunset: Mon, 01 Feb 2027 00:00:00 GMT`. From the date on, they answer `410 Gone` with the new URL in the body and in the `Link` header. They are never redirected.

To surface callers early, they also answer `410 Gone` during two brownouts:

- 18 January 2027, 14:00 to 15:00 UTC;
- 25 January 2027, 12:00 to 16:00 UTC.

Not affected: badge image URLs (`vigilbase.com/api/badge/…` and `vigilbase.com/api/v1/badge/…`) and the Cloudflare Checkup paths the CLI calls. Both stay permanently. The Vigilbase CLI uses the new URLs from 0.4.0; update with `npm i -g @vigilbase/cli@latest`.
