# TaskMaster HTML QA & x402 API Audit
> TaskMaster HTML QA & x402 API Audit is a paid API for AI agents from taskmaster-x402.vercel.app, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).
Runs deterministic QA checks on HTML source and audits x402 API security, Bazaar discovery, and OpenAPI readiness without triggering payment on the inspected endpoint.

## 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 taskmaster-html-qa-x402-api-audit-9fbefc2d -d ''
```
Example prompt: Can you audit this HTML source for me — check for duplicate IDs, broken internal references, and external dependencies, and give me a quality score? Here's the full HTML: ...
## When to prefer this
Choose this endpoint when you need deterministic, rule-based HTML QA (duplicate IDs, external references, internal link resolution) with a numeric quality score, or when auditing an x402 API for security and Bazaar/OpenAPI readiness without risking a live payment settlement. Prefer it over generic HTML validators when you need a machine-readable JSON score suitable for CI pipelines or agent workflows.
## Known failure modes
- HTML payload exceeds 1 MB JSON limit — request rejected
- Malformed JSON body — parsing error returned
- Empty or missing html field — validation fails with error
- Network timeout on large HTML inputs
- Non-HTML content passed as html field — checks may produce misleading results
## How this service works
Deterministic HTML QA and bounded x402 API security, Bazaar discovery, and OpenAPI readiness audits that never settle the inspected endpoint's payment challenge.
## Output
Returns a JSON object with a checks map (boolean pass/fail per rule), a summary with byte count, kilobyte size, total/passed check counts, overall score out of 100, and a standaloneCandidate flag, plus a findings object listing any duplicateIds, externalReferences, or missingDirectIdRefs arrays, along with a privacy notice and schemaVersion.
