## 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-coingecko-provider-2eb41484 -d '<json body>'
```

Example prompt: Can you grab the current price of Ethereum and Bitcoin in USD from CoinGecko via Prysm — use the simple_price operation with ids 'ethereum,bitcoin' and vs_currencies 'usd'?

## When to prefer this

Choose this endpoint when you need CoinGecko market data in an autonomous agent context that supports x402 micropayments on Base mainnet, and want a single pay-per-call interface without managing a CoinGecko API key. Ideal for low-frequency lookups where $0.05/call is acceptable and agent-native crypto payment is preferred over traditional API key billing.

## Known failure modes

- Invalid or unsupported operation name returns an error (operation not on allowlist)
- Malformed input parameters rejected by CoinGecko upstream (e.g. unknown coin ID)
- Payment failure via x402 (insufficient USDC balance or Base mainnet transaction failure)
- CoinGecko rate limits or downtime propagated as upstream error
- Missing required 'operation' field causes request rejection

## How this service works

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

## Output

A JSON object with a 'data' field containing the CoinGecko API response (e.g. price maps, market cap, volume), a 'provider' field set to 'coingecko', and an 'operation' field echoing the requested operation name.
