Things To Do API is a developer-focused events knowledge base built for agentic applications that need fast, localized listings of shows, talks, pop-ups, markets, festivals and similar events. It accepts plain-language queries (example: GET /v1/search?q=comedy+in+san+francisco+this+weekend) and returns structured event objects containing fields like title, category, UTC start time, localized date/time, venue name and city, and source/ticket links. The product is agent-ready with a REST endpoint and an MCP transport entry for Claude, a sandbox for testing, and simple agent instructions so assistants can call it directly. San Francisco coverage is live, with New York and Los Angeles marked as coming soon, and the team invites requests for other cities or event types.
Pricing and access are straightforward: free tier with 1,000 calls/month and 60 calls/minute, a pay-as-you-go plan at $5 per 1,000 calls with volume discounts at 100k and 1M calls and a 300 calls/minute rate, and custom enterprise options offering every city, bulk access, SLAs, and any rate. You can try it without a key for up to 50 queries/day or obtain a free API key. Documentation includes OpenAPI, llms.txt, and standard terms/privacy pages.
