Get fonts

get_fonts
Read-onlyIdempotent

List font families and weights. includeUrls=true returns origin webfont URLs and archived resource paths; includeFaces=true includes face ranges. Prefer get_capture_asset(resources[].path) for stored bytes; origins are metadata and can become unavailable.

Input Schema

NameRequiredDescriptionDefault
limitNoMaximum items returned, clamped to 1..300. Default 10.
queryNoCase-insensitive search text. Empty means no filter; matches the fields documented by this tool.
offsetNoZero-based result offset for pagination. Negative values are treated as zero; default is 0.
productYesProduct key, for example finance-ozon-ru
versionYesExact capture version returned by list_versions. Pin the same version across related calls; do not use latest as an alias.
platformYesPlatform type ID from list_platforms.options.platforms[].id (backend CatalogPlatform.view). Use backend IDs verbatim; desktop/mobile are current examples. Environment is selected separately.
environmentNoEnvironment ID from the selected backend platform type in list_platforms.options.platforms[].environments[].id (backend implementation). Omit only when the version has one captured environment. Use captured pairs from list_platforms/list_versions for actual availability.
includeUrlsNoInclude original font download URLs and matching archive resources in compact font summaries. Default false; full faces include URLs regardless.
includeFacesNoInclude full font-face metadata instead of compact font summaries. Default false.

Output Schema

NameRequiredDescriptionDefault
resultYesCaptured fonts with optional faces and original URLs

  3. First observed

TDQS

A4/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already establish readOnly, idempotent, non-destructive behavior. The description adds useful behavioral context by noting that origin URLs are metadata and can become unavailable, and by directing agents to get_capture_asset for stored bytes.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Three tight sentences front-load the main purpose, then explain the two key flags, then add the critical alternative. Every sentence contributes useful information without repetition.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given a rich input schema, an output schema, and annotations covering safety, the description supplies the important caveat about origin availability and the recommended alternative for stored bytes. It is nearly complete, though it could mention its relationship to the singular get_font tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the schema already carries full parameter semantics. The description adds modest clarification about includeUrls returning origin webfont URLs and archived resource paths and includeFaces including face ranges, but most meaning is already in the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource: listing font families and weights. It also distinguishes the stored-bytes use case from metadata by pointing to get_capture_asset. However, it does not explicitly differentiate itself from the singular get_font sibling.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Gives clear guidance on how to use includeUrls and includeFaces and explicitly recommends get_capture_asset(resources[].path) for stored bytes. It lacks explicit when-to-use guidance versus get_font or component typography tools, but the key alternative is named.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
