📝 WalkthroughWalkthroughAdds a Cloudflare Browser Rendering plugin with typed account, screenshot, snapshot, and HTML-scraping endpoints. The plugin includes API-key authentication, response validation, rate-limit handling, package configuration, schema metadata, and provider registration. The remaining changes remove unused imports or normalize formatting. ChangesCloudflare Browser Rendering
Repository cleanup
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟠 High · up to This PR adds four Cloudflare Browser Rendering operations, but the current implementation cannot pass frozen dependency installation and does not correctly handle several Cloudflare response formats, so CI is blocked and the new operations may fail or return incorrect data. The PR is not merge-ready until these issues are fixed. Sequence Diagram(s)sequenceDiagram

Greptile SummaryThe PR adds a Cloudflare Browser Rendering provider with API-token authentication and four operations for accounts, screenshots, snapshots, and scraping. It also registers the provider, but currently includes unrelated changes, uncompilable public endpoint aliases, incomplete endpoint tests, and generator residue.
Confidence Score: 0/5The PR is not safe to merge because it violates the plugin change boundary, fails TypeScript endpoint-key constraints, and lacks required endpoint tests while retaining generator residue. The new plugin’s exported endpoint aliases cannot satisfy their contract-map generic, its tests never exercise the advertised operations, and the pull request includes a large prohibited set of unrelated files. Files Needing Attention: packages/cloudflarebrowserrendering/index.ts, packages/cloudflarebrowserrendering/schema.test.ts, packages/cloudflarebrowserrendering/schema/database.ts, and all files outside the permitted plugin footprint Important Files Changed

During TypeScript checking, these aliases instantiate CloudflareBrowserRenderingEndpoint<K> with names that are absent from CloudflareBrowserRenderingEndpointOutputs, whose keys end in Get or Create. TypeScript therefore rejects all four aliases and fails the package typecheck and CI build.

The package's only test checks schema metadata and never exercises listAccounts, captureScreenshot, takeWebpageSnapshot, or scrapeHtmlElements. Incorrect provider paths, methods, authentication, request bodies, and response mappings therefore pass this test suite, and the package violates the endpoint-coverage gate.

This file retains the generator's TODO and commented example entity, so the completed plugin is rejected by the boilerplate-residue gate. Delete the unused stub or replace it with the intended database schema.

Reject partial viewport input.
If a caller sets only viewportWidth or only viewportHeight, Line 15 evaluates to false and the adapter omits the viewport. The operation silently ignores accepted input. Require both dimensions or reject partial viewport input.

Cloudflare Browser Rendering API screenshot snapshot scrape response format content screenshot base64 JSON envelope official documentation
💡 Result:
The Cloudflare Browser Rendering API provides several endpoints for interacting with web pages, with distinct response formats for screenshots and data scraping [1][2]. Screenshot Endpoints The /screenshot and /snapshot endpoints both return visual captures of a webpage [3][4]. - Screenshot Encoding: The returned screenshot is a base64-encoded image string [5][3]. - Format Options: You can specify the encoding type (binary or base64) and the image format (png, jpeg, or webp) in your request [1]. - Snapshot Envelope: The /snapshot endpoint returns a JSON envelope containing the requested page formats [3][2]. A typical response structure includes fields like accessibilityTree, content (HTML), markdown, and screenshot [5][3]. - Screenshot Field: Within the /snapshot response object, the screenshot is returned as a base64 encoded string under the key screenshot [3]. Scrape Endpoint The /scrape endpoint is designed for structured data extraction rather than image capture [6][7]. - Response Format: It returns a JSON object containing a result array, where each entry corresponds to a requested CSS selector [8][6]. - Content: Each result contains the extracted HTML, inner text, element dimensions (height, width, top, left), and element attributes [8][6][7]. Standard API Envelope All these endpoints typically follow a standard Cloudflare API response wrapper, which includes: - success: A boolean indicating the status of the request [9][10][6]. - errors: An optional array of objects providing error codes and messages if the request fails [9][8].

site:developers.cloudflare.com/api/resources/browser_rendering/subresources/screenshot create response content-type binary base64 success result
💡 Result:
There is no standard HTTP Content-Type header for base64-encoded data. Base64 is an encoding mechanism, not a media type. When transmitting binary data encoded as base64 within an HTTP API response, the Content-Type should typically be set to application/json if the data is nested within a JSON object, or to the specific media type of the original binary content (e.g., image/png) if the response body consists solely of the encoded string. When designing an API response that includes a success result along with base64-encoded data, a common pattern is to wrap the data in a JSON structure that includes a success indicator. An example of such a response structure is: { "success": true, "data": "SGVsbG8gd29ybGQ=" } In this implementation, the Content-Type header should be set to application/json. If the intended use is to return only the binary content as base64 without JSON wrapping, you may use text/plain or a custom media type, though this is less standard for binary transport. To serve binary data natively, it is generally recommended to transmit the raw bytes with the appropriate media type (e.g., application/octet-stream or image/jpeg) and allow the client to handle the decoding, rather than forcing a base64 encoding layer on the HTTP transport.

site:developers.cloudflare.com/api/resources/browser_rendering/subresources/snapshot create response content screenshot optional format
💡 Result:
When working with technical workflows that require response content and optional screenshots, such as those provided by the Cloudflare Browser Rendering API, you can request multiple output formats in a single request [1][2]. The Cloudflare Browser Rendering Snapshot API allows you to retrieve the following optional formats as part of its result object [1][3]: - Content: The HTML content of the page [3][2]. - Screenshot: A base64-encoded image of the page [3][2]. - Markdown: The rendered Markdown content [3][2]. - Accessibility Tree: An object representing the accessibility tree nodes [1][3]. To create a response that includes these elements, you can specify the desired formats in your API request [2]. The API also provides configuration options such as: - Screenshot Customization: You can control the appearance of the screenshot using viewport, fullPage, or clip options [1][2]. - Page Loading Control: You can manage how the page loads before capture using gotoOptions and various waitFor parameters [1][2]. Example usage typically involves a POST request to the snapshot endpoint, where you provide the URL or HTML content and specify the formats you wish to receive in the response [2].

site:developers.cloudflare.com/api/resources/browser_rendering/subresources/scrape create response result array selector
💡 Result:
The term response result array selector is not a standard programming paradigm or universal API design pattern. Instead, it refers to a specific data structure used in the Cloudflare Browser Rendering API when performing web scraping tasks [1][2]. In this context, the elements parameter accepts an array of objects, where each object contains a selector field (typically a CSS selector) used to identify specific elements on a webpage [1][2]. When the API returns the results of this request, the response contains a result field, which is an array of objects [1][2]. Each object in this result array maps the requested selector back to the actual data extracted from the element (such as its HTML content, attributes, and geometric properties like height, width, and position) [1][2]. Essentially, this structure allows developers to request multiple elements via CSS selectors in a single API call and receive a paired, array-based response that links each selector to its corresponding scraped result [1][2].

Cloudflare Browser Rendering REST API OpenAPI screenshot snapshot scrape response schema github
💡 Result:
Cloudflare provides a Browser Rendering REST API that enables developers to programmatically perform browser-based tasks such as capturing screenshots, scraping elements, and extracting page content [1][2]. API Endpoints and Functionality: - Screenshot (POST /accounts/{account_id}/browser-rendering/screenshot): Captures a screenshot of a webpage. You can provide either a URL or custom HTML [3][4]. Options include viewport customization, clipping, full-page capture, and background transparency [1][4]. - Snapshot (POST /accounts/{account_id}/browser-rendering/snapshot): Returns both the page's HTML content and a screenshot [1][5]. It provides access to the accessibility tree, raw HTML, and markdown content [5][6]. - Scrape (POST /accounts/{account_id}/browser-rendering/scrape): Extracts specific meta attributes (like height, width, or text) from selected elements on a page [1][7]. OpenAPI Schema and Documentation: - Official Documentation: The primary resource for the Browser Rendering REST API is the Cloudflare Developers documentation, which provides detailed endpoint references, request parameters, and model definitions [1][5][3]. - OpenAPI Specifications: Cloudflare maintains OpenAPI schemas for its services [8]. While specific community-maintained repositories may host individual YAML files (often used for SDK generation) [7], the most accurate reference for the API schema is the official Cloudflare API documentation, which dynamically documents the available parameters and response structures [1][6]. Key Implementation Details: - Authentication: Requests require a custom API Token with the Browser Rendering - Edit permission [2][9]. - Usage Metrics: Every REST API response includes an X-Browser-Ms-Used header that reports the browser time consumed for the request in milliseconds [2][9]. - Limitations: If advanced automation or persistent browser sessions are required, Cloudflare recommends using Workers Bindings instead of the REST API [2].

Cloudflare Browser Rendering screenshot endpoint response is image/png or JSON base64 encoding option official
💡 Result:
The Cloudflare Browser Rendering API provides two primary ways to retrieve screenshots, depending on the endpoint used [1][2]. 1. /screenshot Endpoint: When using the POST /accounts/{account_id}/browser-rendering/screenshot endpoint, the API returns the screenshot directly as a raw binary image (image/png by default) [3][2]. This is the standard behavior when performing a direct request (e.g., via curl) where the output is saved to a file [3][2]. 2. /snapshot Endpoint: When using the POST /accounts/{account_id}/browser-rendering/snapshot endpoint, the API returns a JSON response that includes the screenshot as a base64-encoded string within the result object [4][5][6]. Regarding the encoding option: The Browser Rendering API allows you to specify the encoding for your screenshot in the screenshotOptions of your request. You can explicitly set the "encoding" parameter to either "binary" or "base64" [1]. If you require the response to be base64-encoded in your JSON payload, you should ensure this parameter is configured accordingly in your API request [1]. Summary of Key Details: - Default format: The screenshot is returned as a binary image (image/png) by default when using the /screenshot endpoint [3][2]. - JSON base64 support: The /snapshot endpoint returns base64-encoded images within a JSON response by design [4][6]. - Configurable options: You can control the encoding (binary vs. base64) and the image type (png, jpeg, or webp) via the screenshotOptions object in your request [1][7]. Note that if you set the quality parameter, you must also specify a supported image type (like jpeg) to avoid a 400 error [3][2].

site:github.com/cloudflare/api-schemas browser rendering screenshot.openapi.yml snapshot scrape
💡 Result:
There is no standard or industry-wide relationship between browser rendering, screenshots, and an openapi.yml file. openapi.yml (or openapi.json) is a standard format used to define and document RESTful APIs, enabling automated processes like client library generation, API testing, and contract validation [1][2]. It describes API endpoints, request/response bodies, and authentication methods [3][2]. Browser rendering, screenshotting, and web scraping are tasks typically performed by browser automation tools (such as Playwright, Puppeteer, or Selenium) or dedicated scraping services. While an openapi.yml file can be used to document the API of a scraping service—so that a developer knows how to send a request to trigger a screenshot, for example—the file itself does not perform the rendering or screenshotting [1][4]. If you encountered this combination of terms in a specific project or context, it is likely that: 1. The openapi.yml is acting as the API specification for a service that provides headless browser rendering as a feature. 2. The term "snapshot" may refer to an API-based mechanism for requesting a state capture or result set, which is documented in the OpenAPI specification [3][2].

Align Cloudflare Browser Rendering response handling with the API contract.
captureScreenshotreceives image or text responses, butrequest()always callsresponse.json(). Request base64 output and read it withresponse.text(), or return binary data and update the public schema.takeWebpageSnapshotreturnsresult.content, notresult.html. Requestformats: ['content', 'screenshot']and mapcontenttohtml, or expose the API field.scrapeHtmlElementsreturns an array of{ selector, results }objects, not a record. Update the client and output schema.- Parse and validate each endpoint response after unwrapping the Cloudflare envelope.

Update pnpm-lock.yaml for this package.
The frozen install fails because the new dependency specifiers are absent from the lockfile. Commit the regenerated lockfile. This blocks CI before build, typecheck, and test steps run.
