Properties

Name	Type	Description
url	string
formats	array
onlyMainContent	boolean	Strip navigation, ads, and boilerplate; keep main article content only
renderJs	booleannull	null = auto-detect, true = force JS rendering, false = skip JS rendering
waitFor	integer	Milliseconds to wait after JS rendering before extracting content
includeTags	array	CSS selectors / HTML tags to include in extraction
excludeTags	array	CSS selectors / HTML tags to remove before extraction
jsonSchema	object	JSON Schema describing the structured output shape for the 'json' format
basis	boolean	Return per-field evidence alongside the 'json' format: each top-level scalar schema property comes back as a Basis with an honest status. Requires a JSON schema; off by default, and when off the reque
headers	object	Custom HTTP request headers forwarded to the target URL
cssSelector	string	CSS selector to narrow content extraction to a specific element
xpath	string	XPath expression to narrow content extraction to a specific element
chunkStrategy	object	Strategy for chunking the extracted markdown
query	string	Query string for BM25/cosine chunk filtering (used with chunkStrategy)
filterMode	string	Filtering algorithm to rank chunks against query
topK	integer	Number of top chunks to return after filtering (default: 5)
proxy	string	Per-request proxy URL (http/https/socks5). Overrides global config.
proxyList	array	Per-request proxy pool to rotate among (BYOP). Takes precedence over proxy and server config.
proxyRotation	string	Rotation strategy for proxyList (default: sticky_per_host)
country	string	2-letter ISO 3166-1 alpha-2 country code for residential proxy egress (e.g. 'us', 'gb')
stealth	boolean	Override stealth mode for this request (null = use global config)
actions	object	Unsupported Firecrawl parameter — returns a clear error if supplied
extract	object	Firecrawl-compatible extract object (e.g. { schema: {...} })
llmApiKey	string	BYOK: LLM provider API key for structured extraction (overrides server key)
llmProvider	string	Per-request LLM provider override
llmModel	string	Per-request LLM model identifier override
baseUrl	string	Per-request LLM base URL override for Chat Completions-compatible or Responses-compatible providers (e.g. https://api.deepseek.com/v1)
summaryPrompt	string	User-supplied instructions appended to the summary system prompt (capped at 500 chars)
maxContentChars	integer	Maximum bytes of scraped content sent to LLM for 'summary' format (capped at 200 KB)
renderer	string	Pin this request to a specific renderer. A non-auto browser tier implies renderJs:true unless renderJs:false is set. impersonated-http is a JS-less tier that presents a real Chrome TLS fingerprint; it
deadlineMs	integer	End-to-end deadline budget in milliseconds (default: 8000, max: 60000)
debug	boolean	When true, response includes debugExtraction trace with every candidate the extractor considered
changeTracking	object	Activated when formats includes 'changeTracking'. The format entry is the plain string; options ride on this sibling field.
goal	string	Plain-language monitor goal for the meaningful-change judge
judgeEnabled	boolean	Run the LLM meaningful-change judge on a changed page (requires goal)
parsers	array	Document parser directives. Omit = auto-parse PDFs. Empty array = disable parsing.
screenshotFullPage	boolean	Capture the whole page rather than the viewport, for `formats: ["screenshot"]`.
maxAge	integer	How old a cached copy of this fetch may be, in milliseconds. 0 always fetches. Clamped to a 24 hour ceiling. Extraction options (formats, schema, selectors) are not part of the cache key, so a second
storeInCache	boolean	Set false to read the cache without writing to it.
