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 the tool name ('checkpoint_load'), a boolean indicating whether the checkpoint was found, the full checkpoint record (or null if not found), an array of warnings, the timestamp of when the check was performed, and a result_status string (e.g. 'PASS').
Example use cases
Retrieve deployment go-live evidence
“Can you load the last verification checkpoint we ran for staging.myapp.io? I want to confirm the DNS, TLS, and HTTP checks all passed before we promote to production.”
Audit saved site health snapshot
“Pull up the stored checkpoint record for shop.mybrand.co.uk — I need to see the TLS and screenshot evidence from our last verification run and any warnings that were flagged.”
Confirm prior verification for compliance report
“Fetch the checkpoint record for api.myservice.com so I can include the HTTP and DNS verification status and the timestamp in our infrastructure compliance report.”
Technical details
Endpoint
POSThttps://tdagentutility.co.uk/v1/checkpoint-load?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to retrieve a previously stored verification result rather than trigger a fresh check — ideal for auditing, compliance reporting, or confirming a known-good state without incurring the cost of a new HTTP/DNS/TLS/screenshot run. Prefer this over a live verification endpoint when the goal is to load cached evidence quickly.
Side effects
- Checkpoint not found: 'found' is false and 'record' is null — the checkpoint ID or domain does not match any stored record
- Expired or stale checkpoint: record exists but 'checked_at' timestamp is old, warnings may indicate staleness
- Invalid input: missing or malformed checkpoint identifier causes a 400-class error
- Service unavailable: upstream verification store is unreachable, resulting in a 5xx error
