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 counter key, current integer value, version number, result status (e.g. PASS), timestamps for creation, last update, expiry, and the check time, plus any warnings. The agent can use the value field to track cumulative call counts.
Example use cases
Tracking verification check frequency
“Every time you run a deployment verification on my site, increment the 'site-checks' counter so I can see how many checks have been performed and when the last one happened.”
Agent workflow invocation logging
“After each HTTP health check you run for my agent pipeline, tick the 'http-check-runs' counter and report back the running total and the timestamp.”
Monitoring repeated DNS verification events
“I want to count every DNS verification attempt for my domain rollout — increment the 'dns-verify' counter each time and let me know the current count and version.”
Technical details
Endpoint
POSThttps://tdagentutility.co.uk/v1/counter-increment?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a lightweight, persistent, server-side counter that increments atomically and returns the new value with versioning and timestamps — particularly within agent workflows that are already using the TD Agent Utility verification suite and paying via x402 USDC microtransactions. Prefer this over building local state when you need a durable, auditable tally that survives agent restarts.
Side effects
- Missing or empty counter key returns an error or default behavior
- Counter key not found may return zero or an initialization response
- Network timeout results in no state change and an error response
- Invalid payload format returns a 400-level error
- Payment failure via x402 prevents the call from executing
