# PriceOf > Structured, verified pricing data for 50+ SaaS products. Built for AI agents and developers. PriceOf is a REST API and MCP server that provides machine-readable pricing for SaaS products. We track pricing plans, features, historical changes, and normalized cost-per-seat metrics so that agents and developers don't have to scrape vendor pages or hallucinate prices. ## Access - **Anonymous**: 20 queries/day per IP. No signup. Just `curl https://api.getthepriceof.com/v1/pricing?product=notion`. - **Free**: 100 queries/month with email signup. - **Paid**: $29/mo (2K queries), $99/mo (10K queries), enterprise custom. ## Key endpoints - `GET https://api.getthepriceof.com/v1/pricing?product={slug}` — Full pricing for a product - `GET https://api.getthepriceof.com/v1/pricing?product={slug}&plan={plan_slug}` — Specific plan - `GET https://api.getthepriceof.com/v1/products` — List all tracked products - `GET https://api.getthepriceof.com/v1/compare?products={a,b,c}&team_size=N` — Compare + calculate team cost - `GET https://api.getthepriceof.com/v1/search?q={query}` — Full-text search ## MCP server Available via npm: `npx @priceof/mcp-server`. Works with Claude Desktop, Cursor, Windsurf, and any MCP-compatible agent. Published to the official MCP Registry, Smithery, Glama, and PulseMCP. ## Why this exists - 40%+ of B2B SaaS hides pricing behind "Contact Sales" — agents can't extract what doesn't exist on the page - Pricing changes constantly (Notion changed pricing 3x in 2 years); agents trained on old data hallucinate prices - Every vendor structures pricing differently (per-seat, per-usage, tiered, hybrid); agents can't normalize this - Phone numbers are wrong 36% of the time in LLM responses (Seer Interactive study). Pricing is likely worse because it changes more often. ## Products tracked _(Product list temporarily unavailable.
