## 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 cambrian-x402-solana-hourly-price-api-57127b74
```

Example prompt: What was the hourly price of Solana over the past 24 hours? Use the Cambrian x402 price feed to pull the SOL hourly data.

## When to prefer this

Choose this endpoint when you need pay-per-use, agent-native Solana hourly price data without committing to a subscription. Ideal for autonomous agents that only need price data occasionally and want to pay micropayments per call via x402. Prefer over subscription-based price oracles when cost efficiency at low volume matters.

## Known failure modes

- Payment not included or insufficient USDC (402 Payment Required)
- Invalid or missing query parameters returns empty or error array
- Rate limiting if too many calls made in rapid succession
- Stale or delayed data if upstream blockchain data source is lagging

## How this service works

Pay-per-use blockchain and social data for autonomous agents.

## Output

Returns an array of hourly price records for Solana (SOL), including price values indexed by hour, suitable for time-series analysis, charting, or trading signal generation.
