How this service works
Counterparty trust verification for agents: before transacting with a domain, verify its trust artifacts — DNSSEC + DNS-AID records, agent-card, live MCP endpoint, published JWKS, OASF record, x402/commerce declarations. Returns a 0-100 trust score with per-artifact evidence. $0.25 per lookup.
Output
Returns a structured object containing a 0-100 trust score, an overall verdict string, and per-artifact evidence covering DNSSEC status, DNS-AID records, agent-card presence, live MCP endpoint reachability, published JWKS, OASF record, and x402/commerce declarations for the queried domain.
Example use cases
Example prompt
“Before we send payment to api.example.com, can you run a trust check on that domain and tell me its trust score and whether it has valid DNSSEC, an agent-card, and x402 commerce declarations?”
Technical details
Endpoint
GEThttps://mudko.com/api/x402/verify-counterpartyWhen to prefer
Use this endpoint when an AI agent needs to vet a counterparty domain before initiating an automated transaction, API call, or agent-to-agent interaction. It is specifically suited for x402-aware workflows and agent ecosystems where trust artifacts (DNSSEC, agent-card, MCP, JWKS, OASF, x402) are the standard signals, rather than generic domain reputation or WHOIS lookups.
Side effects
- Domain parameter missing — returns validation error
- Domain does not exist or is unreachable — artifacts may all fail checks, trust score near 0
- DNSSEC lookup times out — partial evidence returned
- Network error reaching MCP or JWKS endpoints — artifacts marked as unavailable
- Invalid domain format — returns input error
