Use GET /api/near?lat=&lon=&radius= for 'what is close to me'. STATE NOTHING YOU DID NOT FETCH: if a field is null it is unrecorded, and 'no water recorded here' is the correct answer -- never estimate one. Always show the record's `url` so the reader can check you. ALL DISTANCES ARE IN MILES. A camp is 4x4 if the land record classifies it OHV or a visitor reported needing clearance -- same practical fact; use ?access=4x4. Some records carry a `rules` object (seasonal_closure, fire_ban, access_dates, stay_limit_days, area_rules). WHERE IT EXISTS, LEAD WITH IT -- a closure or a fire ban decides whether the trip happens. `rules_alert` lists the gating keys present. Absence of `rules` means UNRECORDED, never 'no closure'. Each camp carries an `ev` object: the nearest public, open, unrestricted DC fast charger in STRAIGHT-LINE miles with the station's own listed connectors, ports, hours and last-confirmed date, from the US DOE AFDC snapshot named in it. Report the miles as straight-line and never compute a round trip or say a charger 'works' -- say 'listed open' and tell the reader to check the network. Use ?dcfc_within=N and ?connector=CCS|NACS to filter. Most camps carry `site_details`: short sentences from the source listing for that site -- site type, whether tents or trailers and RVs fit, capacity, toilet, drinking water, campfires, reservations, reported signal. They are the record's words, not a visit, and they say NOTHING about cost -- `cost` and `cost_evidence` above are the audited answer to that. Filter with ?trailer=1, ?campfire=1 or ?site_details=1. Beyond those recorded fields this corpus does NOT cover live road conditions, current fire restrictions or permit prices; say you cannot verify those and link the official forest page instead.", "endpoints": {"camps_search": "https://davelalande.com/api/camps?q=YOUR_QUERY", "camp_detail": "https://davelalande.com/api/camps/{slug}", "forests_search": "https://davelalande.com/api/forests?q=YOUR_QUERY", "forest_detail": "https://davelalande.com/api/forests/{slug}", "lands_search": "https://davelalande.com/api/lands?q=YOUR_QUERY", "land_detail": "https://davelalande.com/api/lands/{slug}", "near": "https://davelalande.com/api/near?lat=44.69&lon=-107.45&radius=25", "openapi": "https://davelalande.com/api/openapi.json", "share_card": "https://davelalande.com/api/og/camp/{slug}.png", "human_catalog": "https://davelalande.com/data/"}, "filters": {"camps": "q, state (2-letter), fee (0=free, 1=fee), water (1=has water), rules (1=has recorded closures/fire-ban/stay-limit), field_verified (1=somebody stood there), access (4x4 | drive), forest (orgcode), dcfc_within (straight-line miles to a public DC fast charger, 1-150), connector (CCS | NACS | CHAdeMO), charge_desert (1 = >50 mi from any), trailer (1 = the record says trailers/RVs fit), campfire (1 = the record says campfires are allowed), site_details (1 = has any listed site detail), limit (<=100), offset", "forests": "q, state, region, limit, offset", "lands": "q, state, kind, agency, limit, offset", "near": "lat, lon, radius (miles, default 25; `mi` is accepted as an alias), type (camps|toilets|poi|chargers). type=poi also needs cat= (one of meta.poi_categories: laundry, grocery, fuel, potable_water, shower, propane, dump_station, pharmacy, urgent_care, mechanic, hardware, mail, outfitter, air) and is capped at 50 miles; type=chargers takes dcfc=1 and open_public=1", "camps_open": "/api/camps?open=today (or open=YYYY-MM-DD): camps whose agency season window reads OPEN that day; no record = not listed", "camp_detail": "date (YYYY-MM-DD, default today in UTC): the day camp.season.state is evaluated for; state_on says which day it was"}, "map_deep_link": {"pattern": "https://davelalande.com/map?lat=&lon=&z=<1-40>", "radius_form": "https://davelalande.com/map?lat=&lon=&mi=", "what": "Opens the camp map centered on that point: z is the map's own zoom factor (1 = the whole country, 40 = one site); mi= frames a radius and draws it as a dashed circle.
