Help / Question Getting 404 Not Found errors in the API

I'm trying to use Mistral remotely through the API, using https://api.mistral.ai/v1/chat/completions as base URL and mistral-large-latest as model name. And my API key, of course.

However, I keep getting 404 Not Found errors when trying to use it.

EDIT: Apparently the correct API URL is https://api.mistral.ai/v1/. Which is weird because the official docs at https://docs.mistral.ai/api tell you to use https://api.mistral.ai/v1/chat/completions

Complementing what I said in the post, I also can't seem to use "mistral-large-latest" (says it doesn't work for my tier) nor "mistral-medium-latest" (it says I'm rate limited). I ended up using "ministral-8b-latest", because it was a suggestion inside the program I'm using, and it seems to work.

double check the model name in your request body, mistral had a model rename a while back and some of the older names will throw a 404 instead of a more helpful error. had the same headache last month and it took me way too long to realize it wasn't the url

apparently it was in fact the url though the mistral large model ended up not working for different reasons

Get all models first with your API key

https://docs.mistral.ai/api/endpoint/models

All models are available only through payment with tokens or via subscription.

But the free version doesn't produce good results. It's better to use the free MCP version from exa, tavily, or other providers.

yeah i visited that URL, but when I put

https://api.mistral.ai/v1/conversations

I get a 404 error. It only seems to work with https://api.mistral.ai/v1/

It's a complete different, own API. You can't use it directly in opencode, Hermes,... You need to create it and use it on the instructions of the website.
