## When to prefer this

Choose this endpoint when you need cryptocurrency market data without the friction of API key registration or subscriptions, especially in autonomous agent contexts where micropayment-per-call via x402 on Base is preferable to managing credentials. Ideal for low-frequency or on-demand queries where a $0.01/call cost is acceptable and multi-source fallback reliability is valued over raw throughput.

## Known failure modes

- Payment failure: x402 micropayment not accepted or wallet has insufficient USDC on Base, resulting in 402 Payment Required
- Rate or quota issues if underlying data providers are throttled
- Stale data if cache has not refreshed and primary source is unavailable
- Empty or partial response if no query parameters match known assets
- Network timeout if edge cache miss causes upstream latency spike

## 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 cryptocurrency market data such as asset prices, trading volumes, market capitalizations, and related metrics, sourced from multiple public data providers with edge caching and multi-source fallback for reliability.
