Error message

wikipedia API error: ${data.error.info || data.error.code}

What it means

The opencli wikipedia page command throws CommandExecutionError when the MediaWiki API responds with JSON containing an `error` object (e.g. invalidpage, badparams, rate-limited). The message surfaces the API's `info` description, falling back to the error `code`. It means the request reached Wikipedia but the API refused it rather than returning query results.

Solutions

1. Read the info text in the message — it names the exact MediaWiki error code (e.g. invalidlang, ratelimited) and fix the corresponding argument
2. Verify the --lang code is a valid Wikipedia language (test https://<lang>.wikipedia.org in a browser)
3. Retry after a delay if the code indicates rate limiting
4. Update opencli if the error persists, as API params may have changed

Example fix

// before
opencli wikipedia page "Earth" --lang xx
// after
opencli wikipedia page "Earth" --lang en

const lang = 'en';
if (!/^[a-z-]{2,8}$/.test(lang)) throw new Error(`unsupported lang: ${lang}`);

function isApiErrorBody(d) {
  return !!d && typeof d === 'object' && !!d.error && typeof (d.error.info ?? d.error.code) === 'string';
}

try {
  const row = await run('wikipedia page', ['Earth', '--lang', lang]);
} catch (e) {
  if (String(e.message).startsWith('wikipedia API error:')) {
    const info = e.message.slice('wikipedia API error:'.length);
    console.error(`Wikipedia refused the request: ${info}`);
  } else throw e;
}

When it happens

Trigger: Calling `opencli wikipedia page <title>` where wikiFetch returns 200 OK but the body is {error: {code, info}} — e.g. an invalid language code rejected by the API, malformed title parameters, or MediaWiki-level rate limiting/unrecognized parameter values.

Common situations: Typo in --lang producing an unsupported language code, special characters in titles breaking query params, hitting api.php while rate-limited by shared IP, or a MediaWiki API deprecation changing accepted params.
