## 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 md-fastdb-in-crypto-price-pulse-71778f16 -d '<json body>'
```

Example prompt: What's the current USD price of Ethereum right now, with a confidence score? Also check the price of the token at contract address 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum.

## When to prefer this

Use this endpoint when you need a real-time, aggregated USD price for any crypto asset — especially when you need flexibility to look up by ticker symbol, CoinGecko ID, or raw on-chain token contract address, and when confidence scoring matters for downstream decisions. Prefer it over single-source price feeds when data reliability signal is important.

## Known failure modes

- Unknown symbol or CoinGecko ID returns a 404 or empty result
- Unrecognized chain:address pair may return low confidence or no data
- Network latency from aggregation sources may cause slight delay
- Misspelled symbol or ID returns an error or null price
- Low-liquidity tokens may return a low confidence score or no price

## How this service works

Real-time USD prices for any crypto asset — majors by symbol, any CoinGecko id, any token by chain:address. Aggregated, with confidence score.

## Output

Returns the current USD price of the requested crypto asset (by symbol, CoinGecko ID, or chain:address), aggregated across sources, along with a confidence score indicating data reliability.
