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 indicating whether the lock was successfully acquired (acquired: true/false), the lock token if acquired, the expiry timestamp, a result_status (e.g. PASS), the checked_at timestamp, and any warnings encountered during the attempt.
Example use cases
Exclusive deployment verification gate
“I'm about to kick off a full deployment verification for staging.myapp.com — HTTP, DNS, TLS, and a screenshot. First, grab a lock so no other agent starts the same checks while I'm running them.”
Multi-agent coordination for site audit
“We have three agents that might all try to verify the same production site at once. Can you acquire a lock for the verification job on prod.example.com before any of them starts the audit?”
CI pipeline verification lock
“Right before the post-deploy verification step in the pipeline for api.myservice.co.uk, acquire a lock so we don't get duplicate verification runs if two deploys land close together.”
Technical details
Endpoint
POSThttps://tdagentutility.co.uk/v1/lock-acquire?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to coordinate multiple agents or prevent concurrent runs of website verification checks on the same target. It acts as a distributed mutex before invoking the HTTP, DNS, TLS, or Chromium screenshot verification tools on the same service. Prefer it in CI/CD pipelines, multi-agent fleets, or any workflow where duplicate verification runs would waste resources or produce conflicting results.
Side effects
- Lock already held by another agent — acquired returns false and lock_token is null
- Service unavailable or timeout — HTTP 5xx response
- Invalid or malformed request body — HTTP 4xx with error detail
- Payment failure via x402 — payment not accepted, request rejected
- Lock expired between check and acquire — race condition returning acquired: false
