## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability vextorium-crypto-price-api-3ceb014c -d '<json body>'
```

Example prompt: What are the current prices of BTC, ETH, and SOL in EUR?

## When to prefer this

Choose this endpoint when you need quick, aggregated cryptocurrency spot prices for one or more assets in USD or any ECB-supported fiat currency, especially when you want a single call for multiple tickers or need EUR/GBP/JPY pricing sourced from ECB FX rates. Prefer it over exchange-specific APIs when you want aggregated (not exchange-specific) pricing.

## Known failure modes

- Unknown or misspelled ticker returns null or error for that coin
- Unsupported currency code causes request failure
- Malformed chain:contract address returns error
- Network or upstream DefiLlama/ECB outage may return stale or unavailable data
- Missing required 'coins' field returns validation error

## How this service works

232 pay-per-call data APIs for AI agents: official statistics and economy (ECB, Fed, Eurostat, World Bank, SEC, BOE, INE), crypto prices and sentiment, Spanish public data, compliance (sanctions, VAT, IBAN, LEI), science, weather, web and developer tools and local AI text tools. Pay in USDC via x402.

## Output

A JSON object containing a timestamp, a map of each requested coin symbol to its current price as a float, the currency code, and a source attribution string (e.g. 'DefiLlama (aggregated price) + ECB (FX)').
