Google Patents API endpoint
Use Crawlora's Patents Detail API to extract supported public Google Patents data as structured JSON. This page includes request parameters, cURL examples, response schema, error behavior, credit cost, and a Playground link for testing before integration.
/googlepatents/detailReturns a single patent's normalized detail: title, abstract, inventors, assignees, dates, legal status, CPC/IPC classifications, claims, description, patent citations, cited-by patents, family members, and similar documents. `number` is a publication number such as `US10758101B2`, `EP1000000A1`, or `WO2020123456A1`. Public data, sourced from Google Patents' server-rendered detail pages. To search or browse by keyword, inventor, or assignee instead of a known publication number, use `/googlepatents/search`. Developers commonly use this endpoint for data enrichment, monitoring, research dashboards, internal automation, and agent-native workflows that need repeatable structured public web data. Authentication uses the documented Crawlora headers, and usage is metered with the credit cost shown on this page.
Request parameters are generated from the active endpoint catalog. Required values must be sent before Crawlora can call the upstream public web data source.
| Parameter | Type | Required | Default | Description | Example |
|---|---|---|---|---|---|
| number | string | Yes | Publication number, e.g. US10758101B2 | ||
| lang | string | No | Language code for the translated page, default en | ||
| x-api-key (header) | string | Yes | API key required |
curl -X GET "https://api.crawlora.net/api/v1/googlepatents/detail?lang=en" \ -H "x-api-key: $CRAWLORA_API_KEY"
Send your scraping API key in the x-api-key header. Use the console API Keys page to rotate or select the active key.
Endpoint usage is metered in credits. The plan prices, included credits, limits, and overage rates below match the active backend billing configuration.
| Plan | Price | Included credits | Daily cap | Rate limit | Overage |
|---|---|---|---|---|---|
| Free | $0/mo | 2,000 | 500 daily credits | 5/min | No overage |
| Starter | $9/mo | 20,000 | 5,000 daily credits | 15/min | $0.75/1,000 overage credits when enabled |
| Growth | $29/mo | 100,000 | 25,000 daily credits | 45/min | $0.45/1,000 overage credits when enabled |
| Pro | $79/mo | 400,000 | No daily cap | 120/min | $0.30/1,000 overage credits |
| Business | $199/mo | 1,200,000 | No daily cap | 300/min | $0.20/1,000 overage credits |
| Enterprise | $499/mo | 5,000,000 | No daily cap | 1,000/min | $0.12/1,000 overage credits |
This endpoint is executed through Crawlora's managed scraping infrastructure.
Some targets require real browser execution because the data is loaded through JavaScript, dynamic rendering, or interaction-like browser behavior.
For supported endpoints, Crawlora can route requests through a managed browser cluster. This allows Crawlora to execute JavaScript, load dynamic content, apply browser-level request behavior, and normalize the rendered result into JSON.
You do not need to operate your own Playwright, Puppeteer, Chrome, proxy, queue, or retry infrastructure.
Crawlora does not silently return bad data when the upstream page cannot be used.
| Status | Common failure case |
|---|---|
| 400 | Invalid input or missing required parameter |
| 429 | Plan or endpoint rate limit exceeded |
| 500 | Internal execution error |
| 502 | Upstream platform failed, returned unusable HTML, or served a challenge page that could not be resolved |
When possible, Crawlora returns structured error context so your integration can retry, back off, or inspect the request.
