--- name: z87:manpages description: 142K Linux man pages with AI-generated cheat cards, category tags, use-frequency scores, and plain-english descriptions. Field-qualified search across name, description, options, synopsis, section, package, and category. --- Anonymous: 600 tok/min. Key: `GET https://z87.ai/api/use` → `X-Api-Key` header, 6000 tok/min. On `429`, wait 1s. Search man pages: /search?q=name:curl — field-qualified search. Fields: name, short_description, description, options, synopsis, extra, section, package, category. Examples: /search?q=name:ls — search by command name /search?q=category:networking — all networking tools /search?q=category:filesystem section:1 — filesystem user commands /search?q=name:git section:1 — Git user commands only /search?q=description:socket section:2 — socket-related system calls /search?q=category:crypto — cryptography tools and libraries /search?q=category:shell&min_freq=4 — commonly-used shell tools Categories: networking, filesystem, process, security, text_processing, development, database, graphics, audio, packaging, shell, monitoring, crypto, compression, web, mail, hardware, virtualization, container, backup, dns, firewall, logging, scheduler, memory, disk, printing, terminal, math, science, game, font, i18n, configuration, authentication, ipc, kernel. Frequency filter: &min_freq=4 returns only commonly-used tools (1=obscure, 5=daily essential). Sections: 1 (User Commands), 2 (System Calls), 3 (Library Functions), 4 (Special Files), 5 (File Formats), 6 (Games), 7 (Miscellaneous), 8 (System Administration), 9 (Kernel Routines). Search returns: name, one_liner (plain-english description), card (cheat sheet with common invocations), categories, use_frequency, section, package. Detail: /details/{id} — full man page with synopsis, description, options, see_also, card. Autocomplete: /suggest?q=sys — prefix completion on names. Random: /random — random man page. All endpoints accept both **GET with query parameters** and **POST with JSON body**. ## Endpoints ### `https://z87.ai/api/manpages/search` Field-qualified search.
