## When to prefer this

Choose this endpoint when you need DeFi protocol volume data without the overhead of registering for API keys or managing accounts.

## Known failure modes

- Payment not received or insufficient USDC — returns HTTP 402
- Protocol name not recognized or unsupported — may return empty or error response
- Upstream public data provider outage — fallback may return stale or partial data
- No query parameters provided — may return default or generic volume data
- Rate limiting at upstream sources — potential latency increase or partial response

## How this service works

Market and on-chain data, paid per call in USDC on Base through the x402 protocol. No accounts, no API keys. Sources are public data providers; the value added here is keyless access, edge caching, multi-source fallback and normalised responses.

## Output

A normalized JSON response containing DeFi protocol volume metrics (e.g. total volume, time period, protocol identifier) aggregated from public on-chain data sources, with edge-cached delivery and multi-source fallback for reliability.
