How this service works
Independent website and deployment verification for AI agents: HTTP, DNS, TLS and Chromium screenshot evidence. Three deterministic tools, x402 V2 Base USDC.
Output
Returns a JSON object containing a unique inbox_id, a callback_url where verification events should be posted, an expires_at Unix timestamp, max_event_size and max_event_count limits, a result_status of PASS or FAIL, a checked_at ISO timestamp, and any warnings encountered during creation.
Example use cases
Pre-check inbox for deployment pipeline
“Before I kick off my deployment verification checks, set up a callback inbox that lasts 1800 seconds so the results can be delivered back to me.”
Short-lived inbox for one-off site audit
“Create a temporary inbox that expires in 600 seconds — I need somewhere to collect the HTTP, DNS, and TLS results for a quick one-off audit of a client site.”
Agent fleet verification coordination
“Spin up a verification inbox with a 24-hour TTL so my agent fleet can send back Chromium screenshot and deployment check results throughout the day.”
Technical details
Endpoint
POSThttps://tdagentutility.co.uk/v1/inbox-create?utm_source=zero.xyzWhen to prefer
Use this endpoint as the first step in a multi-step verification workflow where you need to receive asynchronous results from HTTP, DNS, TLS, or Chromium screenshot checks. It is the correct choice when you need a deterministic, short-lived callback URL rather than polling or synchronous responses. Prefer this over generic webhook services when the downstream tools are the TD Agent Utility verification suite.
Side effects
- TTL value exceeds maximum of 86400 seconds — returns validation error
- TTL value below minimum of 1 second — returns validation error
- Payment not provided or insufficient USDC — returns 402 Payment Required
- Service temporarily unavailable — returns 5xx error
