How this service works
Pay-per-call web extraction, on-page SEO audits and text analytics for AI agents. Paid in USDC on Base via x402 — no accounts or API keys.
Output
Returns a JSON object containing an SEO letter grade (e.g. 'C'), a numeric score (0-100), and an array of detected issues each with an id and severity level (e.g. 'error', 'warning'). This allows agents to quickly triage what's wrong on a page and prioritize fixes.
Example use cases
Pre-launch landing page SEO check
“Before I publish my new product landing page at https://mystore.com/launch, can you audit its on-page SEO and tell me what errors I need to fix?”
Competitor SEO benchmarking
“Run an SEO audit on my competitor's homepage at https://competitor.com — I want to see their score and what issues they have so I can compare.”
Blog post SEO quality check
“I just wrote a new blog post at https://myblog.com/2024/best-practices — can you check its on-page SEO score and flag any errors or warnings I should address?”
Technical details
Endpoint
GEThttps://web-intel-x402.x402-web-intel-api.workers.dev/v1/seo-audit?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, structured on-page SEO analysis of a specific public URL without setting up an account or API key. It is ideal for agents that need to programmatically evaluate SEO health, detect missing meta tags, or score pages as part of a content or marketing workflow. Prefer this over full-site crawlers when you only need a single-page audit with per-call pricing and no subscription commitment.
Side effects
- URL is not publicly accessible or returns a non-200 status — audit cannot be performed
- Invalid or malformed URL provided — request rejected with an error
- Page requires JavaScript rendering that the crawler cannot handle — incomplete results
- Payment fails or is insufficient — x402 payment error returned before audit runs
- Rate limiting or timeout on the target URL — partial or failed audit
