Invalid CometAPI base URL: ${options.apiBase}. Expected http

Error message

Invalid CometAPI base URL: ${options.apiBase}. Expected https://api.cometapi.com/v1/ or compatible endpoint

What it means

Validation error thrown by CometAPI.validateConfig (invoked from the constructor) when a custom apiBase is supplied that fails CometAPI.isValidApiBase — i.e. it is not https://api.cometapi.com/v1/ or a compatible OpenAI-style endpoint. Prevents constructing a client pointed at an unusable URL.

Solutions

1. Use exactly https://api.cometapi.com/v1/ as apiBase
2. If you need a proxy/custom gateway, ensure its URL ends with a /v1/-style OpenAI-compatible path accepted by isValidApiBase, or omit apiBase entirely
3. Remove the apiBase option if you intend the default endpoint
4. Check for typos: scheme (https), host, and /v1/ suffix

Example fix

// before
new CometAPI({ apiBase: 'https://api.cometapi.com', ... });
// after
new CometAPI({ apiBase: 'https://api.cometapi.com/v1/', ... });

const BASE = 'https://api.cometapi.com/v1/';
if (apiBase && !/^https:\/\/[^/]+\/v1\/?$/.test(apiBase)) apiBase = BASE;

function isValidCometBase(u: string): boolean {
  try { const x = new URL(u); return x.pathname.replace(/\/+$/, '') === '/v1'; } catch { return false; }
}

try { new CometAPI(opts); } catch (e) {
  if (e instanceof Error && e.message.startsWith('Invalid CometAPI base URL')) opts.apiBase = 'https://api.cometapi.com/v1/';
  throw e;
}

When it happens

Trigger: Instantiating CometAPI with options.apiBase set to a typo'd domain, a non-/v1/ path, a URL missing the protocol, or a third-party proxy that doesn't mimic the CometAPI OpenAI-compatible shape.

Common situations: Copy-pasting an OpenAI base URL (https://api.openai.com/v1/) instead of CometAPI's, trailing-slash or /v1/-missing variants, self-hosted proxy URLs that need to be allowlisted/extended in isValidApiBase.
