## When to prefer this

Choose this endpoint when you need pay-per-call DeFi yield data without a subscription, paid in USDC on Base via x402 micropayment. Best for agents that need occasional yield lookups without committing to a recurring API plan. Avoid if you need deeply documented schemas, guaranteed uptime, or high-volume queries.

## Known failure modes

- 402 Payment Required if USDC micropayment on Base is not included or fails
- Empty or stub response due to undocumented schema (example:{})
- Service unavailability from Render.com free-tier hosting (cold starts, downtime)
- Malformed input due to unclear schema (nested 'properties' property in input schema)
- Rate limiting or quota exhaustion

## 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 DeFi yield data including protocol names, pool identifiers, APY/APR rates, and related metrics for yield-bearing opportunities across decentralized finance protocols, delivered as a JSON response after micropayment via x402.
