# Kallipolis Proof — Deep Resolve Evidence API

> Kallipolis Proof — Deep Resolve Evidence API is a paid API for AI agents from proof.platoskallipolis.com, paid per call via x402, $0.2/call, status unknown (last checked 2026-09-15).

Performs deep evidence resolution on a public HTTPS domain or Base blockchain address, returning a verdict, confidence score, signals, and findings about the target's legitimacy or identity.

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-7d3c349f -d '<json body>'
```

Example prompt: Can you deep-resolve the evidence for 'example.com' and tell me whether it's verified, what signals came back, and how confident the result is?

## When to prefer this

Choose this endpoint when you need deep, multi-signal evidence resolution for a specific domain or Base blockchain address — particularly when trust verification is critical before interacting with a protocol, sending funds, or integrating with an external agent. It is especially suited for AI agent workflows that require a structured verdict with a confidence score rather than a simple ping or whois lookup. Prefer it over generic reputation APIs when you need Base-address-specific evidence or when operating in a web3/onchain context.

## Known failure modes

- Invalid query (not a valid HTTPS domain or Base address) — likely 400 error
- Private or non-public domain — insufficient evidence, low confidence score
- Unknown Base address with no on-chain history — empty signals and findings
- Payment failure via x402 — request blocked before resolution
- Rate limiting or service unavailability — 5xx error
- Ambiguous target that matches neither domain nor Base address pattern

## 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

Returns a JSON object containing: a 'verdict' string (e.g. 'verified'), a 'confidence' number between 0 and 1, a 'targetType' enum ('domain' or 'base-address'), an array of 'signals' (evidence items supporting the verdict), and an array of 'findings' (detailed observations about the target).
