Try any of 919 endpoints — live.
Pick an endpoint, load a working example, tweak the params, and send — no signup to try. Results render the way the data deserves; raw JSON, headers & code are one tab away.
Render a URL in headless Chromium and run a full axe-core WCAG audit → score, severity summary, per-issue evidence + fix-hints, and an honest manual-review list.
Page URL to audit (http/https; bare domains get https:// prefixed). Private/internal/metadata targets are SSRF-blocked on every hop.
Conformance standard to test against (selects the axe rule tag set).
Viewport to render at before auditing (responsive a11y differs by breakpoint).
Add axe 'best-practice' rules on top of the chosen WCAG standard (usability checks beyond strict conformance).
Also return the rules that PASSED (passes[]) — useful for evidence reports. Default false (smaller response).
Return axe 'incomplete' results — checks that need human review (folded into needs_review). Default true.
Attach a curated fix_hint to each issue (default true).
Restrict the audit to these axe rule ids (comma-separated or JSON array). Empty = all rules for the standard.
Disable these axe rule ids for the run (comma-separated or array).
Only audit elements inside these CSS selectors (axe context include).
Skip elements matching these CSS selectors (axe context exclude — drop third-party widgets you don't control).
Cap the number of returned issues (0 = no cap). Summary counts are always complete. (0–1000)
Navigation wait condition before auditing.
Additionally wait until this CSS selector is visible (15s budget) — the reliable signal for heavy SPAs.
Extra settle delay after load before auditing, 0-5000ms. (0–5000)
Browser locale (Accept-Language + Intl), e.g. en-US, de-DE, ar-EG.
Override the browser User-Agent.
Extra request headers (JSON object). Cookie/Authorization are stripped (no-login content policy).
Bypass the audit cache and force a fresh render+audit.
