Identify website fonts by URL

Give your Agent a domain or exact page URL to find reported font families, fallback names, element usage and available font-file references. Review cache context when comparing the result with the page you see.

Use scrape-fonts-context-dev through my existing Toolmu connection; follow https://toolmu.com/SKILL.md if setup is needed. Stay within my existing authorization and budget. Provide either domain or directUrl in queryParams, never both. Apply supported maxAgeMs and timeoutMS settings, keeping supplier timeout below the Tool request timeout. Summarize reported families, fallback names, element labels, usage statistics and available font references with cache context. Distinguish fallback declarations from rendered fonts and repeated weight URLs from distinct files. Do not infer accuracy, full-site coverage, freshness or reuse permission.

Task:
Check [website link] or [specific page link]. List the font names and where the page says they are used, other fonts it may switch to, and any available download links.

Identify website fonts by URL

You receive

Get a font report with family names, fallback lists, element labels and supplier usage statistics. When available, a family-keyed reference map provides display names and file URLs; cache status and age describe the returned result.

Start with your task

Check [website link] or [specific page link]. List the font names and where the page says they are used, other fonts it may switch to, and any available download links.

What to know

The report covers an inspected page, not every page or interaction state of a website. Usage percentages are not accuracy scores or confirmed visible-text coverage. Font references do not establish distinct weight files, download availability or permission to reuse them.

Inputs & outputs

Input schema

Input schema
Field / Path	Type	Requirement	Meaning
Font lookup options`queryParams`	`object`	Optional	Choose a domain or one exact page URL, with optional cache-age and supplier-timeout settings.
Website domain`queryParams.domain`	`string`	Optional	Domain of at least three characters for website resolution. Use this instead of directUrl. Minimum length `3`
Maximum cache age`queryParams.maxAgeMs`	`integer`	Optional	Nonnegative integer in milliseconds. The documented default is 7,776,000,000 (90 days), with an effective range of 86,400,000–31,536,000,000 (one day–one year). Setting 0 does not guarantee a fresh capture. Minimum `0` Maximum `9007199254740991`
Exact page URL`queryParams.directUrl`	`string`	Optional	Full URL identifying the page to inspect, bypassing domain resolution. Use this instead of domain. Format `uri`
Supplier timeout`queryParams.timeoutMS`	`integer`	Optional	Optional integer from 1,000 to 300,000 milliseconds. Keep it below the Tool request timeout. Minimum `1000` Maximum `300000`

Result schema

No fixed output contract is available. Field types reflect saved result evidence; individual responses can differ.

Result schema
Field / Path	Type	Meaning
Detected font records`result.fonts`	`array`	Font-family records reported for the inspected page, with fallback names, element labels and usage statistics when available.
Reported font family`result.fonts[].font`	`string`	Font-family identifier reported for this record.
Fallback font names`result.fonts[].fallbacks`	`array`	Reported fallback-family names or generic families. A listed fallback is not proof that it rendered the visible text.
Element usage labels`result.fonts[].uses`	`array`	Reported CSS selectors or element types associated with the font, such as h1, p or button; not proof of font rendering on every listed element.
Reported word count`result.fonts[].num_words`	`number`	Supplier-reported count of analyzed words associated with this family, rather than a whole-site text census.
Reported element count`result.fonts[].num_elements`	`number`	Supplier-reported count of analyzed elements associated with this family, rather than every element on the website.
Reported word percentage`result.fonts[].percent_words`	`number`	Reported share of analyzed words associated with the family, not identification accuracy or confirmed visible-text coverage.
Reported element percentage`result.fonts[].percent_elements`	`number`	Reported share of analyzed elements associated with the family, not a confidence score or proof of complete website coverage.
Font reference map`result.fontLinks`	`object`	Map keyed by returned font-family identifiers. Entries can contain a display name, source-type label and weight-keyed file URLs. Different weight keys may repeat one URL and do not prove distinct files or supported weights.
Page loading state`result.finalDOMState`	`string`	Supplier-reported loading state at capture, such as loaded or still-loading. It does not confirm that every font or interaction state was observed.
Reported domain`result.domain`	`string`	Domain reported for the inspected target.
Cache context`result.cache_metadata`	`object`	Supplier-reported cache status and age for the font result.
Cache age`result.cache_metadata.age_ms`	`number`	Returned cache age in milliseconds, rather than a measurement of each font file’s age.
Cache status`result.cache_metadata.status`	`string`	Supplier-reported cache state, such as hit.
Lookup status`result.status`	`string`	Supplier status for the font lookup; success does not establish that all fonts or page states were observed.

Choose one. domain lets the supplier resolve the website; directUrl identifies the specific page you want to inspect. Use an exact URL when different pages may use different fonts. A request does not establish a complete font inventory for the whole site.

Questions about this tool.

Should I use a domain or an exact page URL?

Are fallback font names fonts that were actually rendered?

Do the reported percentages measure identification accuracy?

Do file entries provide separate, reusable fonts for every weight?

Does a cache age of zero guarantee a new capture?
