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).
Example use cases
Vetting a DeFi protocol's domain
“Before I connect my wallet to defiprotocol.xyz, can you run a deep evidence check on that domain and tell me if it's verified, what signals were found, and the confidence score?”
Checking a Base wallet before payment
“I want to send USDC to 0x1234abcd5678ef901234abcd5678ef901234abcd on Base — can you resolve the evidence on that address and tell me the verdict and any findings before I do?”
AI agent identity validation
“We're about to integrate with an AI agent that claims to be at agentprotocol.io — can you run a deep resolve on that domain so I can see whether it's legitimate and what the evidence shows?”
Technical details
Endpoint
POSThttps://proof.platoskallipolis.com/api/v1/deep-resolveWhen to prefer
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.
Side effects
- 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
