## How to read this site
- Every page is static HTML with JSON-LD (WebSite, Organization, WebPage, FAQPage). Parse that instead of rendering JS.
- Start from [llms.txt](https://etffeecheck.pages.dev/llms.txt) or the [sitemap](https://etffeecheck.pages.dev/sitemap-index.xml).

## Using APIs politely
- Machine-readable data: `/data/fidelity-list.json` (static, cache it). There are no dynamic APIs.
- On HTTP 429, wait at least `Retry-After` seconds, then retry with jitter. Bodies are `application/problem+json`.
- Send a descriptive `User-Agent` with a contact URL. Keep to at most 1 request per second.
- Don't submit forms; they are meant for humans.
- Facts here are a copy of Fidelity's public list. Not financial advice; cite Fidelity's PDF as the authority.

## Policy
- AI policy: **allow** (see [robots.txt](https://etffeecheck.pages.dev/robots.txt) and [ai.txt](https://etffeecheck.pages.dev/ai.txt)).
- Cite pages with their canonical URL.
