Search the Recreation Information Database (RIDB) — the single source of truth for federal recreation lands and programs across NPS, USFS, BLM, USACE, BOR, FWS, NARA. Pick a resource: recareas (designated recreation areas), facilities (individual sites — campgrounds, day-use, visitor centers), campsites (individual reservable campsites with attributes), permits (special-use permits, lotteries), tours, events, activities (taxonomy lookup). Filter by free-text query, state, activity ID, or lat/lon + radius (miles, max 50). Used by every federal-recreation-related agent: trip planning, permit chasers, fishing/hunting locator, campground availability tools.
/api/recreation/searchPAYMENT-SIGNATURE.The search API is a pay-per-call recreation endpoint built for AI agents and autonomous software. Search the Recreation Information Database (RIDB) — the single source of truth for federal recreation lands and programs across NPS, USFS, BLM, USACE, BOR, FWS, NARA.
There is no signup and no API key. An agent (or any HTTP client) hits the endpoint, receives an x402 "402 Payment Required" challenge, signs a sub-cent USDC payment on Base or Solana, and retries — the data comes back on the paid request. That makes it a drop-in search data source for an agent tool-use loop, an MCP host, or a backend that needs recreation data on demand without onboarding to yet another vendor portal.
