## 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 tradingview-screener-via-sitecheck-crypto-finance-c41c9a3f
```

Example prompt: Pull up the TradingView screener for the US stock market and show me the top 20 instruments with their current price and percent change today.

## When to prefer this

Choose this endpoint when you need a broad market overview with price and percent-change rankings across US equities, crypto, forex, or global markets without requiring a brokerage account or API key. It is ideal for agents that need quick screener snapshots sourced directly from TradingView's public scanner. Prefer alternatives if you need real-time streaming quotes, historical OHLCV data, or deep fundamental screening with custom filters.

## Known failure modes

- Invalid market value (not america/crypto/forex/global) returns an error
- Limit outside 1-50 range may return an error or be clamped
- Payment failure results in no charge and a 402 response
- TradingView upstream unavailability may cause timeout or stale data
- Missing required 'method' or 'type' fields in input object returns a schema validation error

## How this service works

TradingView stock screener results for one market (default america): symbol, last price and daily change, in TradingView's default order. Read-only scanner query; no filters beyond market and count.

## Output

Returns a JSON object containing an array of financial instruments (up to the requested limit), each with a symbol name, closing price, percent price change, and exchange:symbol identifier. Also includes the market queried, the source URL (TradingView scanner), the timestamp of the check, and the total count of instruments in the full screener.
