FAQ
- What counts as a request?
- One API call to any endpoint counts as one request. Fetching a tool by ID (
GET /tools/:id), running a search (GET /search), listing a category, or pulling score history — each is one request. MCP server calls made by your AI assistant also count. Requests that return errors (4xx, 5xx) do not count against your limit. - What is the rate limit on the free tier?
- The public free tier allows 100 requests per day, enforced per IP address. There is no per-minute burst limit for typical usage. If you hit the daily limit, requests return a
429 Too Many Requestsresponse and the limit resets at midnight UTC. For higher volume, join the Pro waitlist. - How does billing work for Pro API?
- Pro API is billed monthly at $49/mo via Stripe. Your billing cycle starts the day you activate. You can cancel anytime — your key stays active through the end of the current period. Annual billing (2 months free) will be available at launch. Billing launches with Phase 2 — join the waitlist to be first notified.
- Is my MCP tool already in the index?
- Almost certainly yes. AgentRank crawls GitHub nightly and indexes every repo matching MCP server and agent tool patterns. Search the leaderboard to find your listing. All indexed tools are visible for free — paid tiers add enhanced listings, analytics, and featured placement.
- Do I need to pay to appear in the index?
- No. The index is free and automatic. Listings are generated from public GitHub data. Sponsored tiers are for maintainers who want featured placement, analytics, and verified badges — not for basic indexing.
- How are Sponsored Listings labeled?
- Sponsored placements are labeled "Sponsored" — transparently and prominently. We don't hide paid placements as organic rankings. Traffic data is available before you commit. If the numbers don't justify the spend, we'll tell you.
