It supports both synchronous and asynchronous rendering, webhooks, render links, custom projects, and session-cookie-based rendering behind logins. It includes stealth and proxy features to avoid bot-blocking and CAPTCHAs, and can save outputs directly to a wide range of S3-compatible and cloud storage providers (AWS S3, GCS, Azure Blob, Backblaze B2, Cloudflare R2, DigitalOcean Spaces).

    "Authentication details for the API (API key handling, scopes) are not surfaced in the provided checks, so agent-driven onboarding clarity is inferred rather than verified.",
    "No explicit status page surfaced in the checked endpoints, so uptime reliability must be inferred from docs rather than live telemetry."
  ],
  "recommendations": [
    "Expose a lightweight usage/status endpoint in llms.txt or robots-linked docs so agents can verify quota and uptime programmatically.",
    "Publish a concise machine-readable pricing table (JSON/YAML) alongside the marketing page to reduce parsing loss for agents summarizing costs.",
    "Consider a small always-free tier (e.g., 100 renders/mo) to increase adoption and make agent-led trials frictionless.",
    "Surface an API key rotation/scopes guide directly in llms.txt for faster agent onboarding.",
    "Add explicit rate-limit and error-code documentation to improve first-try success for automated retries."
