New: Riddle Proof

Browser evidence your agent can hand back.

Riddle Proof turns previews, production URLs, and black-box browser flows into reviewable receipts: what was checked, what passed, what failed, and which artifacts prove it.

Good Catch Diary

Real bugs found by cheap browser proof: clipped iframes, preview route escapes, request-body leaks, async races, and auth-boundary failures.

Evidence manifest

Each catch includes the claim, browser checks, screenshots, run receipts, console captures, and the reusable proof pattern.

Source optional

Many browser-visible defects can be detected from the outside with a URL, viewports, and a repeatable proof profile.

The Script API

Write Playwright. Send it to Riddle. Get results.

Just write Playwright

const result = await fetch("https://api.riddledc.com/v1/run", {
  method: "POST",
  headers: {
    "Authorization": "Bearer YOUR_API_KEY",
    "Content-Type": "application/json"
  },
  body: JSON.stringify({
    script: `
      await page.goto("https://example.com/login");
      await page.fill("#email", "user@example.com");
      await page.fill("#password", "secret");
      await page.click("button[type=submit]");
      await page.waitForURL("**/dashboard**");
    `,
    include: ["screenshot", "console", "har"]
  })
}).then(r => r.json());

// result.screenshot — base64 PNG of the final page
// result.console   — every console.log, warn, error
// result.har       — full network trace

Rich results

Get back screenshots, console logs, network HAR, assertion results, and downloaded files—not just pixels.

Full Playwright API

Use any Playwright method—selectors, waits, assertions, network interception. No proprietary DSL to learn.

Pack work into sessions

30 seconds of browser time per job — run multiple navigations, screenshots, and actions in one call.

Assert without vision

Check selectors and URLs in your script before screenshotting. Cheaper than sending every page to a vision model.

Or just grab a screenshot

Same endpoint, simpler input

const response = await fetch("https://api.riddledc.com/v1/run", {
  method: "POST",
  headers: {
    "Authorization": "Bearer YOUR_API_KEY",
    "Content-Type": "application/json"
  },
  body: JSON.stringify({ url: "https://example.com" })
});

const { screenshot } = await response.json();
// screenshot contains your PNG

Built for agents

Vision when needed

Your agent thinks, then acts. Batch navigation, form fills, and checks into one job. Screenshot only at decision points.

Authenticated sessions

Inject cookies, headers, or localStorage. Log in once with your agent, reuse the session across calls.

Assertions without vision

Check if a selector exists or URL matches before deciding to screenshot. Cheaper than sending every page to a vision model.
