## 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 blockchain-iq-crypto-coin-price-market-data-cd5dd60a
```

Example prompt: Pull the current price and 24-hour change for Bitcoin from Blockchain IQ — I want the market cap and all-time high too.

## When to prefer this

Choose this endpoint when you need structured, analyst-curated current price and market data for a single cryptocurrency at low cost ($0.002 USDC per call), especially when you want a clean JSON response including ATH, rank, 24h/30d changes, market cap, and volume in a single call without scraping exchanges directly. Prefer this over generic exchange APIs when you want pre-normalized, individual-investor-focused data with clear disclaimers and attribution.

## Known failure modes

- Unknown or misspelled coinId returns a 404 or error response
- Stale data if the underlying price feed is delayed
- Payment failure if the x402 micropayment of $0.002 USDC is not properly submitted
- Rate limiting if the endpoint is called too frequently without valid payment
- Coins with very low liquidity may have missing or unreliable volume data

## How this service works

Analyst-verified crypto research for individual investors — without the institutional price tag.

## Output

Returns a JSON object containing the coin's current USD price, 24-hour and 30-day percentage changes, market capitalization, 24-hour trading volume, all-time high in USD, market rank, symbol, and name — along with source attribution and a disclaimer that the data is for informational purposes only.
