## 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 bitfinex-tickers-via-sitecheck-crypto-finance-a40bee4e
```

Example prompt: What are the current bid, ask, last price, and 24h change for Bitcoin and Ethereum on Bitfinex? Pull tickers for tBTCUSD and tETHUSD.

## When to prefer this

Choose this endpoint when you need real-time or near-real-time Bitfinex-specific ticker data for one or several trading pairs (up to 10), particularly when you want Bitfinex's own bid/ask/last prices and 24h statistics directly from the source. Prefer this over generic aggregator endpoints when Bitfinex price discovery or Bitfinex-specific volume matters. The pay-per-call model with no signup makes it ideal for infrequent or agent-driven queries without ongoing subscription overhead.

## Known failure modes

- Invalid or missing symbols parameter returns an error — symbols must use Bitfinex v2 format with 't' prefix (e.g. tBTCUSD)
- Requesting more than 10 symbols may result in a partial or error response
- Unknown or delisted symbol returns empty ticker or error from upstream Bitfinex API
- Upstream Bitfinex API unavailability causes failure; payment is not charged on failed calls
- Malformed symbol list (e.g. missing comma separator) results in parse error

## How this service works

Bitfinex spot ticker for one or more pairs (e.g. tBTCUSD,tETHUSD): bid, ask, last, 24h change and volume, from Bitfinex's public v2 ticker endpoint.

## Output

Returns a JSON object with a tickers array, each entry containing symbol, bid, ask, last price, 24h high, 24h low, 24h volume, 24h price change (absolute and percent), plus the source URL and a checkedAt timestamp.
