# Kallipolis Proof — Deep Resolve Evidence API

> Kallipolis Proof — Deep Resolve Evidence API is a paid API for AI agents from kallipolis-proof.handongzhen101.chatgpt.site, paid per call via x402, $0.2/call, status unknown (last checked 2026-09-16).

Resolves evidence and trust signals for a public HTTPS domain or Base blockchain address, returning a verdict, confidence score, and supporting findings.

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 kallipolis-proof-deep-resolve-evidence-api-b9b22e83 -d '<json body>'
```

Example prompt: Can you deep-resolve the trust evidence for 'uniswap.org' and tell me the verdict and confidence score — I want to know if it's safe for my agent to interact with it.

## When to prefer this

Use this endpoint when an AI agent needs a structured, evidence-backed trust verdict for a domain or Base address before interacting with it — especially in Web3 or agentic workflows where autonomous agents must assess counterparty credibility. Prefer this over generic WHOIS or DNS lookup tools when you need a synthesized confidence score and labeled findings rather than raw records.

## Known failure modes

- Invalid or non-public domain returns error or low-confidence result
- Malformed Base address rejected with validation error
- Unresolvable or newly registered domain may return low confidence with sparse signals
- Payment failure via x402 results in 402 response and no evidence returned
- Rate limiting or quota exhaustion may return 429 error

## How this service works

Evidence resolution API for AI agents, domains, protocols, and Base accounts. Pay per call with x402 or buy instant prepaid access.

## Output

A JSON object containing a verdict string (e.g. 'verified'), a confidence score between 0 and 1, an array of signals with supporting detail, an array of findings, and a targetType indicating whether the query was resolved as a domain or Base address.
