Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 prysm-coinstats-provider-e8715fc2 -d '<json body>'
```

Example prompt: Pull the current market data for the top coins from CoinStats — I want prices, market caps, and rankings right now.

## When to prefer this

Choose this endpoint when you need cryptocurrency market data (prices, rankings, market caps) sourced from CoinStats and want to pay per-call in USDC via the x402 protocol on Base mainnet without managing a CoinStats API key directly. It is ideal for AI agents that need pay-as-you-go crypto data access in a crypto-native payment context.

## Known failure modes

- Invalid or unsupported operation name returns an error — must use an allowlisted operation such as 'coins'
- Malformed input parameters may cause a 400-level error from the upstream CoinStats API
- Payment failure or insufficient USDC balance via x402 protocol prevents the request from being fulfilled
- Rate limits or upstream CoinStats API outages may cause 503 or timeout responses
- Missing required 'operation' field results in a validation error

## How this service works

Prysm sells paid, agent-ready provider capabilities over x402 on Base mainnet using USDC.

## Output

Returns a JSON object with a 'data' field containing CoinStats-sourced cryptocurrency information (prices, market caps, rankings, etc.), along with the provider name ('coinstats') and the operation that was executed.
