## 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-protocol-tvl-lookup-385840ff
```

Example prompt: What's the current total value locked for Aave? Pull it from ScriptMasterLabs' DeFi TVL endpoint.

## When to prefer this

Use this endpoint when you need quick, pay-per-call TVL lookups for a named DeFi protocol without committing to a subscription. It is ideal for agents that need occasional or on-demand DeFi TVL data settled in USDC on Base via the x402 protocol, particularly when cost-per-call pricing at $0.001 USDC is acceptable. Prefer this over subscription APIs when usage is sporadic or when crypto-native payment rails are required.

## Known failure modes

- Unknown or misspelled protocol name returns empty or error response
- Protocol not tracked by the data source returns null TVL
- x402 payment failure results in 402 status with no data returned
- Rate limiting or server unavailability on the Render-hosted service
- Stale or delayed TVL data if upstream aggregator is lagging

## 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 total value locked (TVL) for the specified DeFi protocol, typically including the protocol name and its current TVL expressed in USD or a relevant denomination. The response schema is minimal and the example is sparse, so exact field names should be confirmed at runtime.
