How this service works
Cryptocurrency price in any fiat currency — JPY, EUR, CNY, GBP, KRW, INR, AUD, BRL, or 80+ more. Input a coin name or CoinGecko ID (bitcoin, ethereum, solana, btc, eth, sol, etc.) and one or more currency codes. Returns current price, 24h percent change per currency, and last updated timestamp. Free upstream: CoinGecko public API (no key). 85% below specialized fiat oracles. Useful for Asian/European market agents, cross-border DeFi pricing, and multi-currency portfolio valuation.
Output
A JSON object containing the current price of the requested cryptocurrency expressed in each of the requested fiat currencies (e.g. { 'ethereum': { 'usd': 3200.45, 'eur': 2980.12, 'jpy': 498000 } }), sourced from CoinGecko and returned in real time.
Example use cases
Example prompt

Technical details
Endpoint
GEThttps://the-stall.intuitek.ai/cap/crypto-fiat-priceWhen to prefer
Use this endpoint when you need a quick, no-account, no-API-key lookup of a cryptocurrency's current price in one or more fiat currencies, paid per-call with micro-USDC. Prefer this over direct CoinGecko API calls when you want a pay-as-you-go model without managing API keys, or when building an agent workflow on the x402 payment rail.
Side effects
- Unknown coin ticker or CoinGecko ID returns a 404 or empty result
- Invalid fiat currency code returns an error or omits that currency from the response
- Network or upstream CoinGecko outage causes a 502 or timeout
- Missing required 'coin' query parameter returns a 400 validation error
- Insufficient USDC balance or failed x402 payment returns a 402 Payment Required response
