Errors and retries

• Failed requests throw errors.APIError, with statusCode and the response body.
• A 401 is retried once with a fresh token.
• A 429 Too Many Requests is retried up to three times, honouring Retry-After.
• A server error (500, 502, 503, 504) is retried once.

import { errors } from "@pinta365/blizzard-api";

try {
    await client.wow.characterProfile("silvermoon", "nosuchcharacter");
} catch (error) {
    if (error instanceof errors.APIError && error.statusCode === 404) {
        // Not found
    }
}

A 404 doesn't always mean the thing doesn't exist. WoW: Forever characters, for example, only appear from level 10, after a logout: see Characters and guilds.
