coingecko derivatives limit must be <= 500

Error message

coingecko derivatives limit must be <= 500

What it means

This ArgumentError is thrown when the `limit` argument is a valid positive integer but exceeds the hard cap of 500 imposed before querying CoinGecko's /derivatives endpoint. The cap keeps response sizes and API load bounded.

Solutions

1. Lower --limit to 500 or less, e.g. --limit 500
2. Paginate/filter instead (use the symbol substring filter to narrow results)
3. Split large exports into multiple calls of <= 500

Example fix

// before
cli derivatives --limit 5000
// after
cli derivatives --limit 500

const n = Number(args.limit ?? 20);
if (Number.isInteger(n) && n > 500) {
  throw new Error('limit must be <= 500; use the symbol filter or paginate instead');
}

const isWithinCap = (v, cap = 500) => Number.isInteger(v) && v > 0 && v <= cap;

When it happens

Trigger: Calling the derivatives command with --limit greater than 500, e.g. --limit 1000, after passing the positive-integer check.

Common situations: Users trying to fetch 'all' derivatives by passing a very large number, scripts bulk-exporting data without pagination awareness.

Understand the failure class

Background: "Must be a positive integer", "Invalid value", "Unsupported": the invalid-argument-value error family, when a library rejects the value you pass — this error's family across 35 libraries.
