# Parser-Blocking Script Budget Decision

> Parser-Blocking Script Budget Decision is a paid API for AI agents from webtechnik.halowerk.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-23).

Fetches live public evidence from a target URL and returns a pass/fail verdict on whether its parser-blocking script budget meets the documented criterion, along with observation, threshold, evidence source, limitations, and a recommended action.

## 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 parser-blocking-script-budget-decision-1b0156fd -d '<json body>'
```

Example prompt: Check whether example.com passes the parser-blocking script budget criterion — fetch the current live evidence and give me the verdict, the observed count vs threshold, and what action I should take.

## When to prefer this

Use this endpoint when you need a fast, passive, single-verdict decision on whether a specific URL's parser-blocking script count is within budget — especially suitable for CI/CD gates, pre-launch checks, or lightweight monitoring where you want a structured pass/fail with evidence rather than a full multi-metric audit report. Prefer sibling audit or repair-plan endpoints when you need broader multi-criterion analysis or actionable remediation steps.

## Known failure modes

- Target URL is unreachable or returns a non-200 status — endpoint cannot fetch evidence
- Target domain normalizes to a non-public or localhost address — rejected as invalid
- Malformed or too-short target string — schema validation error
- Target page uses JavaScript-only rendering that obscures static script tags — observation may be incomplete
- Rate limiting or network timeout on the target side — partial or no evidence returned

## How this service works

Parser-blocking script budget decision fetches current public evidence from the supplied target and evaluates the documented criterion. It returns the observation, threshold, verdict, exact evidence source, limitations and a mode-specific action. The check is passive: no login attempt, payload injection, exploit, purchase, form submission or load test is performed.

## Output

Returns a structured object containing the observed parser-blocking script count, the documented budget threshold, a binary pass/fail verdict, the exact URL or source of evidence used, any limitations of the passive check, and a mode-specific action recommendation for the inspected target.
