## 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 adam-hale-tools-meta-tags-seo-checker-7d21a17b
```

Example prompt: Can you check the SEO meta tags for https://www.example.com and https://www.example.com/about — I want to see if there are missing canonical tags, how long the titles are, whether the pages are indexable, and any other SEO issues flagged?

## When to prefer this

Choose this endpoint when you need a quick, structured SEO audit of specific URLs — especially for checking canonical tags, title and meta description length compliance, indexability, H1 counts, and named SEO issue codes — without running a full crawler. Ideal for spot-checking up to 3 URLs at a time in automated workflows, pre-launch audits, or competitive research where programmatic JSON output is required.

## Known failure modes

- Private/internal hostnames or IP addresses are rejected (only public hosts on ports 80/443 are allowed)
- More than 3 URLs in a single call may be rejected or truncated
- URLs that return non-200 HTTP status will still be returned but marked as failed with the actual HTTP status code
- Network timeouts or unreachable hosts will appear in the failed count
- Malformed URLs will cause individual result failures

## How this service works

Guides and free-to-run Apify actors for bulk tech stack lookup, sitemap URL export to CSV, TED and UK Find a Tender search, and RSS-to-JSON feed monitoring.

## Output

Returns a JSON object with a results array, each entry containing: the input URL, final redirected URL, HTTP status code, indexability flag, page title and title length, meta description length, H1 count, canonical URL (or null), detected schema.org types, a list of named SEO issue codes (e.g. TITLE_TOO_SHORT, CANONICAL_MISSING, TWITTER_CARD_MISSING), and an issue count. Also returns aggregate counts of succeeded and failed requests.
