Tools of Graunt
	Description		Read-only	Idempotent	Open world
`fetch`Read one Graunt catalog packet by id. Returns its title, description, price and whether an account is needed, its seller-declared rights, and its public URL. A free packet that needs no account also returns its files: small text files (CSV, JSON, Markdown, text and similar) in the text, and a short-lived download link for each listed file in metadata.files (at most 100 per fetch; files_not_listed counts the rest). A video listing also returns metadata.video: its subjects, measured hours, per-hour price with volume tiers, and the seller's declarations.	Read one Graunt catalog packet by id.

`match_video_spec`Find out how many hours of video on Graunt meet a spec, and in which categories. Give the requirements that matter (shortest side, frame rate, clip length, sound, on-screen text, overlays, first and last shots, freezes, slowed footage, releases, clearances, AI generation, uses, delivery); leave the rest out. Returns matching hours per category and per listing: hours that meet every requirement on recorded evidence, and hours that meet every requirement the evidence covers but lack evidence for one or more. Each listing carries its list price, price per hour and volume tier, its hours per category with what each category alone costs where it sells by category, the spec's categories priced as one order, its delivery modes and where each number comes from. Thresholds snap to fixed steps and the answer says which were applied. Give hours_wanted to also get a proposal: whole listings across sellers that reach those hours on recorded evidence, lowest price per measured hour first, each at its seller's own price, for the person you work for to add to their cart. Nothing is held, and short_units is the gap the proposal leaves, not a statement about what Graunt holds.	Find out how many hours of video on Graunt meet a spec, and in which categories.

`search`Search Graunt's catalog of evaluated data from many sellers. Returns matching packets with their id, title, and public URL. Start here to find data, then read one with fetch. search_match.words says how the listings matched the query: ALL (every word, or a synonym of it), SOME (some of the words), WORD_START (words that start with the query's words), SIMILAR_TITLE (titles spelled like the query) or NONE (no listing). On SOME and WORD_START each listing names its matched_words. Each result's type is listing or pool, and search_match describes only listings. Pools use a separate keyword matcher over their public descriptions and data types. When no listing matches, next_steps.post_request_url opens a buyer request with the query filled in.
