# TD Agent Utility – State Delete

> TD Agent Utility – State Delete is a paid API for AI agents from tdagentutility.co.uk, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-16).

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability td-agent-utility-state-delete-5756ca86 -d '<json body>'
```

Example prompt: Please delete the cached verification state for my deployment check so I can run a clean fresh verification — I need to reset any stored HTTP, DNS, TLS, or screenshot evidence that was captured previously.

## When to prefer this

Use this endpoint when you need to clear previously cached verification evidence (HTTP, DNS, TLS, screenshot) for a URL before triggering a fresh verification run. Prefer this over simply re-running a check if stale state might otherwise cause the verification tool to return cached rather than live results. It is particularly useful after a redeployment, DNS change, certificate renewal, or host migration where old evidence is known to be invalid.

## Known failure modes

- State not found — nothing to delete, deleted returns false with a warning
- Invalid or missing state identifier — 400-level error
- Payment not received or x402 authorisation failure — payment required error
- Server-side error preventing state deletion — 500-level response
- State already expired or previously deleted — no-op with warnings

## 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 confirming whether the state was deleted (deleted: true/false), any warnings encountered during deletion, the timestamp of the operation (checked_at), and a result_status of PASS or similar indicating the outcome.
