How this service works
Pay-per-request data toolkit for AI agents — 13 no-auth tools, $0.005 USDC each via x402. Web search, read URL, crypto price/markets/trending, Wikipedia, news headlines, weather, FX rates, IP geolocation, DNS lookup, stock quotes, and domain WHOIS.
Output
Returns a JSON object with the requested vs-currency, total count of coins returned, and a prices map keyed by coin ID — each entry includes the current price in the chosen currency and the 24-hour percentage change (e.g. {"vs":"usd","total":1,"prices":{"bitcoin":{"price":61234,"change_24h_pct":1.83}}}).

Technical details
Endpoint
POSThttps://x402deploy.vercel.app/api/priceWhen to prefer
Choose this endpoint when you need current spot prices and 24-hour momentum for one or more specific cryptocurrencies by their CoinGecko ID, especially in an agent context where no API key management is desired and micropayment-per-call via x402 is acceptable. Prefer this over exchange-specific APIs when you need a unified price across multiple coins in one call.
Side effects
- Invalid or misspelled CoinGecko coin ID returns missing/empty prices for that coin
- Unsupported vs-currency may result in an error or empty response
- Missing required 'ids' field returns a validation error
- Payment failure via x402 (insufficient USDC balance or bad payment header) results in HTTP 402 and no data
- Downstream CoinGecko API outage may cause delayed or stale data
