## When to prefer this

Choose this endpoint when you need a cheap, pay-per-call ETH price lookup (0.001 USDC) with no API key subscription, especially in x402-enabled agent workflows on Base. Best suited for low-frequency spot checks where a micro-payment model is preferred over a monthly subscription to a major data provider like CoinGecko or CoinMarketCap.

## Known failure modes

- Payment not settled — 402 returned if x402 payment header is missing or insufficient
- Rate limiting or service unavailability on the Render-hosted endpoint
- Stale or delayed price data if the underlying data source lags
- Malformed or empty response body due to underdocumented schema
- Network timeout from cold-start on Render free tier

## How this service works

Pay-per-call crypto, RWA, federal, SEC, and compliance APIs. Settled in USDC on Base via x402. Hyphen routes only (e.g. /x402/rwa-aggregates, /x402/gas-tracker).

## Output

Returns the current Ethereum price, likely as a numeric USD value or price object. The response is a pay-per-call result (0.001 USDC per call) settled on Base via x402. Exact response schema is minimal/undocumented but expected to contain the ETH price figure.
