coingecko returned no market data for currency "${currency}"

Error message

coingecko returned no market data for currency "${currency}"

What it means

This CommandExecutionError is thrown when the response contains a market_data object but has no price, market cap, or total volume for the requested quote currency (all three lookups are null). This usually means CoinGecko does not offer market data quoted in that currency for the coin. The message echoes the currency and a hint lists known-supported slugs.

Solutions

Use a supported quote currency: usd, cny, eur, jpy (or gbp, aud, cad, etc.)
Check the supported list at https://api.coingecko.com/api/v3/simple/supported_vs_currencies
Default to omitting --currency (defaults to 'usd')

Example fix

// before
opencli coingecko coin bitcoin --currency usa
// after
opencli coingecko coin bitcoin --currency usd

Defensive patterns

Strategy: validation

Validate before calling

const SUPPORTED = new Set(['usd','eur','gbp','jpy','cny','aud','cad','chf','inr','krw','btc','eth']);
if (!SUPPORTED.has(ccy)) throw new Error(`Unsupported quote currency: ${ccy}`);

Type guard

const isSupportedCurrency = (v) => typeof v === 'string' && supportedVsCurrencies.has(v.trim().toLowerCase());

Try / catch

try { await run(['coingecko', 'coin', id, '--currency', ccy]); } catch (e) { if (/no market data for currency/.test(e.message)) { return run(['coingecko', 'coin', id]); } throw e; } // fall back to usd

Prevention

Fetch /api/v3/simple/supported_vs_currencies and validate currencies against it
Stick to well-known fiat codes (usd, eur, jpy, cny, gbp)
Fall back to the usd default when a currency yields no data

When it happens

Trigger: Calling `opencli coingecko coin <id> --currency <ccy>` where <ccy> passes slug validation but isn't a currency CoinGecko quotes (e.g. 'xyz', 'foo', or a niche/misspelled code like 'usa' instead of 'usd').

Common situations: Guessing currency codes ('usa' vs 'usd', 'eur' vs 'euro'); very rare fiat or crypto quote currencies not in CoinGecko's supported list; transient cases where a currency was dropped.
