# Free Tier Hub — Agent Discovery

This Markdown file is optional guidance for automated readers, not a robots.txt policy.

## Discover
- Human-readable index: https://free-tier.eplus.dev/
- Machine-readable catalog: https://free-tier.eplus.dev/catalog.json
- Sitemap: https://free-tier.eplus.dev/sitemap.xml
- LLM summary: https://free-tier.eplus.dev/llms.txt

## Data model
Each catalog entry includes id, name, category, plan, free_limit, watch_out, pricing_url,
credit_card, commercial_use and last_checked. Treat the official pricing_url as the source
of truth when checking current quotas, billing requirements and commercial eligibility.

## Access and attribution
- Follow the origin's authoritative /robots.txt and applicable service terms.
- Prefer canonical HTML URLs from sitemap.xml, not invented provider detail links.
- Link back to the individual listing or original provider documentation when quoting limits.
- Avoid interpreting unknown card or commercial-use values as a verified yes/no.
