## How to call it through Zero

```sh
zero fetch --capability scriptmasterlabs-defi-yield-api-b2b552b5
```

Example prompt: Can you pull the latest DeFi yield rates from ScriptMasterLabs — I want to see current APYs across major protocols so I can decide where to put my USDC?

## When to prefer this

Choose this endpoint when you need pay-per-call DeFi yield data without a subscription, especially in agentic workflows that can handle x402 micropayments in USDC on Base. It is well-suited for lightweight, occasional queries rather than high-frequency bulk pulls. Prefer this over subscription APIs when cost predictability per-call matters or when integrating into crypto-native agent pipelines already using x402.

## Known failure modes

- 402 Payment Required if x402 USDC payment on Base is not provided or fails
- Empty or minimal response if no matching protocols found for given property filters
- Schema is sparse — response structure may vary or be undocumented
- Service hosted on Render free tier may experience cold-start latency or downtime
- Invalid or malformed properties parameter returns error or empty result

## 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 current DeFi yield data including APY rates, protocol identifiers, and yield metrics for various DeFi lending, staking, and liquidity pool products, paid per-call at $0.001 USDC via x402 on Base.
