Tools of Marathon Scout
	Description		Read-only	Idempotent	Open world
`get_race`Use this when you already have a race's slug from search_races and need its full details, or want to compare up to 5 races side by side (pass slugs). Returns every stored date, the next edition's registration state and when it was checked, Boston-qualifier status, and links for registration, official results by year and live tracking (once confirmed). Links are stable marathonscout.com/go URLs that open the current official page; official_url fields name the destination. Each race counts toward the daily different-races limit. Limits without a key: 20 calls an hour and 40 different races a day; a free key from https://marathonscout.com/developers allows 200 calls and 150 different races a day.

`search_races`Use this when a runner wants to find or choose a race, or asks about a race by name, date or place. Finds marathons, half marathons and ultras worldwide by name, city, region, country, distance, date window, distance from a place or Boston-qualifier status ("a spring marathon in Ohio", "halves within 100 miles of Denver in October"). Returns up to 10 races per call (20 with an API key) with the next race date, registration status and Marathon Scout guide URL, plus total (every match) and next_offset (pass it as offset for the next page). With no text query, results are in date order; a near search with no dates comes back nearest first, each race with distance_miles. Pass looking_for to get registration, results or live tracking links in the same call instead of calling get_race for each race.
