limit must be <= 250 (CoinGecko per_page upper bound)

Error message

limit must be <= 250 (CoinGecko per_page upper bound)

What it means

This ArgumentError is thrown when the requested limit exceeds 250, the maximum per_page value CoinGecko's /coins/markets endpoint accepts. The check runs before the HTTP request so no doomed call is made. To fetch more than 250 coins you must paginate with the page parameter.

Solutions

1. Set limit to at most 250 for a single request.
2. Use the API's pagination: request per_page=250 with page=1,2,3... and merge results for more coins.
3. Clamp in your caller: limit = Math.min(Math.max(1, n), 250).
4. If you truly need the whole market, loop pages until an empty array is returned.

Example fix

// before
await runCli('coingecko', 'top', ['--limit', '500']);
// after
const limit = Math.min(Math.max(1, Number(raw)), 250);
await runCli('coingecko', 'top', ['--limit', String(limit)]);

const n = Number(rawLimit ?? 10);
if (!Number.isInteger(n) || n < 1 || n > 250) throw new Error(`limit must be 1..250, got ${rawLimit}`);

function isValidLimit(v) { return Number.isInteger(v) && v >= 1 && v <= 250; }

try {
  rows = await runCli('coingecko', 'top', ['--limit', limit]);
} catch (e) {
  if (/limit must be <= 250/.test(e.message)) {
    console.warn('Clamping limit to 250; paginate for more');
    rows = await runCli('coingecko', 'top', ['--limit', '250']);
  } else throw e;
}

When it happens

Trigger: --limit 500, --limit 1000, or a config value like 'top 500 coins' passed straight through; Number coercion of a large count from a dashboard config.

Common situations: Users expecting the CLI to auto-paginate past 250; scripts copying a coin list length (>250) as the limit; misunderstanding that per_page is capped by the API, not the CLI.
