## 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 speraxos-defillama-protocol-tvl-api-ba9abc60 -d '<json body>'
```

Example prompt: What's the current TVL for Aave? Look it up from DefiLlama using the protocol slug 'aave'.

## When to prefer this

Choose this endpoint when you need a quick, pay-per-use TVL lookup for a specific DeFi protocol by DefiLlama slug without needing an API key. Ideal for AI agents that need real-time DeFi intelligence on demand, particularly when operating with a crypto wallet capable of x402 USDC micropayments on Base. Prefer this over direct DefiLlama API calls when you need a managed, agent-friendly interface with no key management overhead.

## Known failure modes

- Invalid or unrecognized protocol slug returns an error or empty result
- Protocol not indexed by DefiLlama returns no data
- Payment failure via x402 (insufficient USDC balance or misconfigured wallet) blocks the request
- Network timeout or upstream DefiLlama API unavailability causes a failed response

## How this service works

AI-powered DeFi intelligence APIs payable via the x402 HTTP payment protocol. No API key required — pay per request with USDC on Base. Identity-only (SIWX) endpoints are free for wallets with an agentcash identity.

## Output

Returns the current Total Value Locked (TVL) figure for the specified DeFi protocol, sourced from DefiLlama. Typically includes aggregate TVL value in USD and may include chain-level breakdowns depending on the protocol.
