Moving to api.naut.so

The developer API's address is https://api.naut.so. The old address, https://api.compass.mesa.so, retired on 2 November 2026: every /v1 call there now answers 410 Gone. Change the base URL and keep your key.

The same request with the same key: https://api.naut.so answers 200, the retired host answers 410 HOST_RETIRED naming api.naut.so

What to change

Change the base URL. That is the whole change.

# Before
curl "https://api.compass.mesa.so/v1/me" -H "Authorization: Bearer $NAUT_API_KEY"

# After
curl "https://api.naut.so/v1/me" -H "Authorization: Bearer $NAUT_API_KEY"

Your key is the same. The ck_live_ key you used on the old host works on api.naut.so. You do not need a new one.
Paths, prices, data and credits are the same. Only the host changes. Inside responses, baseUrl names https://api.naut.so, and docs and upgradeUrl point to naut.so.

Retired 2 November 2026.

What the old host answers

Since 2 November 2026, every /v1 call to the old host, and every /account call made with an API key, answers 410 Gone:

{
  "error": {
    "code": "HOST_RETIRED",
    "message": "This API host has moved. Send the same request to https://api.naut.so.",
    "baseUrl": "https://api.naut.so",
    "docs": "https://compass.mesa.so/docs/api/migration"
  }
}

It also sends these headers:

Header	Value	Meaning
`Deprecation`	`@1793577600`	When the old host was deprecated, as a Unix time (RFC 9745).
`Sunset`	`Mon, 02 Nov 2026 00:00:00 GMT`	When it stopped answering API calls (RFC 8594).
`Link`	`<https://api.naut.so/v1>; rel="successor-version"`	Where to go instead. It also links this page as `rel="deprecation"` and `rel="sunset"`.

It is a 410, never a redirect. Your client will not follow it on its own. Read baseUrl, update your config, and send the same request again.
The Link header names the new host too, for a client that reads headers rather than the body.
Nothing is charged for a 410.

New code should read NAUT-API-Version; Compass-API-Version is still sent with the same value.

What does not move

Only the developer API host changed. Old compass.mesa.so links to the website redirect to naut.so.
