If you can use no-cors, set it in the headers, like: var opts = { headers: { 'mode':'cors' } } fetch(url, opts) If you do not control the API, there is little you can do.

L'API Fetch (en anglais, le verbe fetch signifie récupérer) fournit une interface JavaScript pour accéder et manipuler certaines parties du protocole, comme les requêtes et les réponses. Elle fournit également une méthode globale fetch () qui permet un accès pratique aux ressources récupérées de façon asynchrone sur le réseau.

Learn how to use fetch() with no-cors mode to make simple cross-origin requests without CORS headers. See the options, methods, and limitations of this mode.

Learn how to use the mode option in fetch to control cross-origin requests. See the difference between "cors", "same-origin" and "no-cors" modes and their effects on headers, cookies and CORS.

When using JavaScript’s fetch API, you may come across a situation where you need to make a cross-origin request and specify the mode as no-cors. This can be useful when you want to fetch data from a different domain but don’t need access to the response data.

Learn how using `fetch` with `mode: 'no-cors'` can restrict your access to response data and explore alternative methods for cross-origin communication.

https://web.dev › articles › introduction-to-fetch

You can define a mode for a fetch request so that only certain request types resolve. The modes you can set are as follows: same-origin only succeeds for requests for assets on the same origin, and rejects all other requests. cors allows requests for assets on the same origin and other origins that return the appropriate CORs headers.

https://javascript.info › fetch-crossorigin

Fetch fails, as expected. The core concept here is origin – a domain/port/protocol triplet. Cross-origin requests – those sent to another domain (even a subdomain) or protocol or port – require special headers from the remote side. That policy is called “CORS”: Cross-Origin Resource Sharing.

https://developer.mozilla.org › en-US › docs › Web › HTTP › Headers › Sec-Fetch-Mode

The Sec-Fetch-Mode fetch metadata request header indicates the mode of the request. Broadly speaking, this allows a server to distinguish between: requests originating from a user navigating between HTML pages, and requests to load images and other resources.
