## 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 gl1tch-know-your-agent-kya-trust-check-a9c309b5
```

Example prompt: Before I send payment to this agent, can you run a GL1TCH Know Your Agent trust check on the Solana wallet BSq18aJBhxYJgeEbcA3jGQNU1vmwZdo2PQkkpVsK7W6o and tell me its trust score, level, and whether the owner has signature-verified it?

## When to prefer this

Use this endpoint when an AI agent needs to evaluate the trustworthiness of another wallet or agent before executing a payment, trade, or accepting delegated work on Solana or EVM chains. It is specifically designed for agent-to-agent trust decisions, combining signature-verified registration data with on-chain scan history. Prefer it over generic wallet screening tools when you need a structured trust level enum and reasons, not just transaction history.

## Known failure modes

- Missing required 'address' query parameter returns an error (not charged)
- Invalid or malformed wallet address format may return unknown level with score 0
- Unsupported chain value may result in error or fallback to default chain
- Network or service unavailability may cause timeout; endpoint is not charged on failure
- Wallet with no on-chain history in GL1TCH scans returns level 'unknown' with low score

## How this service works

Know Your Agent trust check for an AI-agent wallet, or any wallet, on Solana or EVM chains. Returns a 0-100 trust score, a level (trusted, neutral, caution or unknown), the reasons, and whether the owner proved the wallet with a signature. Built from signature-verified registrations and the wallet's on-chain record in GL1TCH scans. Use it before an agent pays, trades with or accepts work from another agent. Not charged on failure.

## Output

Returns a JSON object containing: the wallet address and chain checked, a numeric trust score from 0 to 100, a categorical trust level (trusted, neutral, caution, or unknown), an array of human-readable reasons explaining the score, a boolean indicating whether the wallet is registered with GL1TCH Know Your Agent, and a boolean indicating whether the owner has cryptographically proved control via a signature.
