## 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 sundayfactoryx-solana-on-chain-data-api-7aa47468
```

Example prompt: Pull the latest Solana on-chain market data and signals from SundayFactoryX right now — I need the JSON response to inform my trading strategy.

## When to prefer this

Choose this endpoint when your AI agent needs Solana-specific on-chain data and can handle x402 micropayments in USDC on Base. It is best suited for autonomous agents with built-in x402 payment clients that need pay-per-call access without subscription overhead. Prefer this over general crypto APIs when you specifically need Solana blockchain metrics and want granular cost control at $0.03 per call.

## Known failure modes

- HTTP 402 returned when payment challenge is not fulfilled — agent must complete x402 USDC payment on Base before data is returned
- Invalid or missing format parameter may return malformed or unexpected response structure
- Network or upstream data provider outages may result in 5xx errors
- Insufficient USDC balance on Base will cause payment failure and no data returned
- Rate limiting or per-agent quotas may restrict repeated rapid calls

## How this service works

Pay-per-call (x402) market-data + research API for autonomous agents. Paid endpoints return HTTP 402 with an x402 v2 payment challenge; pay in USDC on Base with any x402-aware client.

## Output
