DATA/AGENT FOUNDRY — Domain Host Trust
x402
DATA/AGENT FOUNDRY — Domain Host Trust is a paid API for AI agents from foundry-api-production-95ae.up.railway.app, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-31).
Checks the real-time trustworthiness of a public DNS hostname by observing DNS resolution, TLS certificate validity, HTTP security headers, and DNSSEC state.

How this service works
Machine-first active product portfolio. Lifecycle is the CONTROL_SKU; UNKNOWN and DATA GAP results are not billable.
Output
Returns a JSON object containing: a trust decision state (e.g. UNKNOWN, GREEN), DNS resolution addresses and DNSSEC state, TLS certificate validity state, HTTP security headers presence map, freshness metadata (observed_at timestamp, max_age_seconds), billability flag and quantity, provenance list, and a unique run_id and request_id. UNKNOWN and DATA_GAP results are not billed.
Example use cases
Pre-integration domain vetting
“Before we start sending user data to payments.acme-partner.com, can you run a trust check on that hostname and tell me if its TLS cert is valid and whether it has DNSSEC enabled?”
Phishing domain investigation
“I got a suspicious email linking to secure-login-bankofamerica.xyz — can you check that hostname's trust profile and tell me if it resolves, has valid TLS, and what its security headers look like?”
Continuous third-party supply chain monitoring
“We use cdn.thirdparty-vendor.io to serve assets — can you pull the current trust record for that hostname and flag if anything looks off with its certificate or DNS resolution?”
Technical details
Endpoint
POSThttps://foundry-api-production-95ae.up.railway.app/v1/domain-host-trust?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a real-time, machine-readable trust signal about a specific public hostname — especially for pre-integration vetting, phishing domain triage, or supply chain monitoring. It is uniquely structured for agent-driven workflows: UNKNOWN and DATA_GAP results are free, making it safe to probe speculatively. Prefer it over passive WHOIS lookups when you need active observations (TLS, DNS resolution, security headers) rather than registration metadata.
Side effects
- Hostname rejected if it contains URLs, ports, paths, or IP literals (validation error returned)
- Result state UNKNOWN if the host cannot be observed or is unreachable
- DATA_GAP result if observations are incomplete — neither billable
- DNSSEC state returns UNKNOWN_NOT_OBSERVED if DNSSEC data was not collected
- TLS and HTTP header states return UNKNOWN if the host did not respond over HTTPS
