## 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 x402-tunedfor-ai-crypto-market-data-api-dedba587 -d '<json body>'
```

Example prompt: Pull up the current market structure snapshot for BTC — I want the buy/sell ratio, CVD, funding rate, whale bar count, and whether there's any liquidation pressure across exchanges right now.

## When to prefer this

Choose this endpoint when you need a single-call, multi-exchange aggregated view of crypto market microstructure — especially orderflow metrics like CVD, buy/sell ratios, whale activity, and funding rates — rather than raw price feeds or single-exchange data. Ideal for trading agents, market regime detection, and signal generation workflows that need breadth across venues without managing multiple API connections.

## Known failure modes

- Unsupported or misspelled token symbol returns an error or empty snapshot
- Payment of 0.2 USDC not completed causes 402 Payment Required response
- Exchange data unavailable or stale during market outages may return incomplete aggregates
- Network timeout if aggregation across 20 exchanges takes too long
- Invalid request body format causes 400 Bad Request

## How this service works

Cross-exchange crypto market structure API. Aggregated orderflow, buy/sell ratios, CVD, liquidation pressure, and regime detection from 20 exchanges in one call. Free via MCP. Pay-per-call REST in USDC. No signup.

## Output
