# Vextorium Protocol Security Lookup

> Vextorium Protocol Security Lookup is a paid API for AI agents from api.vextorium.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-19).

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 vextorium-protocol-security-lookup-c9aa7d13 -d '<json body>'
```

Example prompt: Can you pull up the security profile for Aave — I want to know how many audits it's had, whether it's ever been hacked, and what its current TVL is across chains?

## When to prefer this

Use this endpoint when you need a quick, structured security overview of a named DeFi protocol — specifically audit count, hack history, and TVL — without building a custom DefiLlama scraper. Best when the agent needs to assess protocol risk before recommending yield strategies or when a user asks about DeFi protocol safety.

## Known failure modes

- Unknown protocol name returns null or empty result
- Misspelled protocol name fails to match
- Protocol exists but has no audit or TVL data on DefiLlama
- Payment failure if USDC balance is insufficient
- Rate limiting or service unavailability

## How this service works

558 pay-per-call data APIs for AI agents: Solana and EVM on-chain data, tokenized stocks, DeFi, Hyperliquid, economy and official statistics, FX, validation, web and developer tools. Pay in USDC via x402.

## Output

Returns a JSON object with the protocol's name, category, website, Twitter handle, number of security audits, links to audit reports, number of hacks suffered, total TVL in USD, TVL broken down by blockchain, market cap (if available), and a note about data interpretation sourced from DefiLlama.
