## 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 seo-file-generator-robots-txt-sitemap-xml-llms-txt-cef6f50d -d '<json body>'
```

Example prompt: Generate a robots.txt file for mybrand.com that disallows /admin and /private, and also produce a sitemap.xml covering /, /about, /blog, and /contact.

## When to prefer this

Choose this endpoint when you need to programmatically generate standard web SEO configuration files (robots.txt, sitemap.xml) or AI-indexing guidance files (llms.txt) on demand without manually authoring them. Ideal for automated site launch workflows, CI/CD pipelines, or agent-driven web project scaffolding. Particularly useful when generating llms.txt, a newer standard not covered by traditional SEO tools.

## Known failure modes

- Missing required domain or paths parameter returns a 400 error
- Invalid ?type= value (not robots, sitemap, or llms) returns an error
- Payment failure or insufficient USDC balance results in 402 response
- Malformed path list may produce incomplete or incorrect file output

## How this service works

Generate robots.txt, sitemap.xml, or llms.txt from a domain + paths spec. ?type=robots|sitemap|llms. Pay-per-call in USDC.

## Output

Returns the fully-formatted file content (robots.txt directives, XML sitemap markup, or llms.txt entries) as a string ready to be saved and deployed, based on the specified domain and paths.
