Tools it offers

8 tools, as the server itself reported during our check on Oct 31, 2026.

• describeWhat Ultrapedia holds: the queryable views, every column and what it means, the allowed values of category columns, and how many races there are. Read this before writing SQL for `query`.
• queryRun one read-only SQL SELECT (SQLite) over the views `races`, `editions` and `sources`. Returns columns and rows; `truncated` is true when more rows exist than `limit` (max 500). Example: SELECT slug, name, date, city FR
• search_racesFind races. `text` matches the name, city or start location; `state` is a two-letter code; `distance_category` is one of the values in `describe`; dates are yyyy-mm-dd and filter the current edition's date. Returns the m
• get_raceEverything about one race: its values, its editions, and for every value the page it was read from and the verbatim quote.
• read_sourceRead a public web page the way this server reads it when it checks a quote: its visible text and its links. Use it before `propose_correction` to copy an exact quote, or to read a race page your own tools cannot open. `f
• propose_correctionSend a value for one field of one race, read from a web page — a correction or a value the index is missing. `field` is a column name from `describe`; `value` is in that column's form and units (gain_m in metres, dates y
• propose_raceSend a US ultramarathon the index does not have yet. Check with search_races first. `quote` is copied verbatim from `source_url` and names the race. One call for each distance (a 50K and a 100M at the same event are two
• report_problemReport something a single value cannot fix: a cancelled or discontinued race, two rows for the same race, a race filed under the wrong distance. Include a source and quote when you have one.
