## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability scriptmasterlabs-defi-tvl-ranking-api-6b8cf0ab
```

Example prompt: Can you pull the current DeFi TVL ranking so I can see which protocols are leading by total value locked right now?

## When to prefer this

Choose this endpoint when you need a quick, low-cost ($0.001 USDC) ranked snapshot of DeFi protocols by TVL, paid permissionlessly via x402 on Base. Prefer it in agentic workflows where micropayment-settled crypto data APIs are required without API key management. Less suitable if you need detailed per-protocol breakdowns, historical TVL trends, or guaranteed real-time freshness.

## Known failure modes

- Payment not settled — x402 payment in USDC on Base required before data is returned
- Empty or minimal response schema — actual field names and structure not documented, agent must handle unknown JSON shape
- Service may be unavailable on free-tier Render hosting during cold starts or inactivity
- Rate limiting or payment failure if USDC balance is insufficient
- Data freshness unknown — TVL figures may be cached or delayed

## 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

A ranked list of DeFi protocols ordered by Total Value Locked (TVL), including protocol names and their respective TVL figures, enabling comparison and analysis of DeFi ecosystem size and dominance.
