Decodo Web Data API vs WebScraping.AI

Decodo Web Data API 67

No OpenAPI or similar contract for the Web Data API; the two published specs cover the proxy account API and dashboard statistics. The MCP server types every input with zod (12 of 25). llms.txt indexes 401 guide pages, each served as Markdown (10). Tool descriptions state purpose and when to use a tool, such as scrape_as_markdown 'when no site-specific tool fits', and link the docs page (14 of 20). Parameters are tabled with defaults, with enumerated proxy_pool, headless and device_type, but headers is a free object and POST bodies are base64 strings (10 of 15). Curl examples on every page, a response code table with fixes and billing, and parser status codes (14 of 15). Paths are versioned at /v1 and the MCP server's releases are tagged by semantic-release, but no API changelog was found (7 of 15). 12 + 10 + 14 + 10 + 14 + 7 = 67.

WebScraping.AI 89

OpenAPI file (version 3.2.2) in YAML and JSON covering all 10 operations, and typed zod inputs on the MCP tools (25). llms.txt, llms-full.txt and a Markdown copy of every page (10). Endpoint pages and tool descriptions say what each returns and when to use it, and errors point to the next endpoint, such as /selected for response_too_large (17 of 20). Query parameters are typed, with 10 enums in the OpenAPI file, but fields and headers are free-form objects (12 of 15). Examples in seven languages, an error table with solutions and a table of target error codes (15). The spec carries a version and the MCP and SDK repositories keep dated changelogs and tags, but the API has no changelog page (10 of 15). 25 + 10 + 17 + 12 + 15 + 10 = 89.

Decodo Web Data API 59

Graded on the hosted lines. Instatus page at status.decodo.com with Web Data API and each legacy scraping API as components, with RSS history (20). In the 90 days to 6 November, every scraping API was out for 2 hours 51 minutes on 30 October, the main outage, with outages of 13 minutes on 26 October and 21 minutes on 15 October across the same components. The rest of the incidents hit proxies, payments or the website. One major (10). Per-plan request rates are published, 10 to 200 a second, though the same page's FAQ says paid plans support 10 to 50 (12 of 15). The response code table tells the agent to wait a couple of minutes on 429 and to retry 500, 524 and 613, which aren't billed, and the MCP client backs off exponentially. No Retry-After or idempotency guidance (7 of 15). No SLA; the License Agreement disclaims uninterrupted service (0). Web Data API is the current, unflagged product (10). 20 + 10 + 12 + 7 + 0 + 10 = 59.

WebScraping.AI 43

Graded on the hosted lines. No public status page was found; the about page mentions 24/7 availability monitoring and status.webscraping.ai did not answer (0). No readable incident history (5). Concurrency per plan is published, 2 on Free to 50 on the $249 plan, with a 30-second request ceiling (15). 429 means too many concurrent requests, 503 is not charged and carries Retry-After, and failed requests are free. No backoff guidance for 429 itself (13 of 15). No SLA; section 14.2 of the terms makes no uptime commitment (0). Generally available since 2019 (10). 0 + 5 + 15 + 13 + 0 + 10 = 43.

Decodo Web Data API 82

The hosted MCP server lists 24 tools, with a toolsets parameter to load only web, search, ecommerce, social_media or ai, and tokenLimit caps page text at 45,000 characters by default with a truncation notice (20 of 25). Markdown output, parsing for templates, crawl limit, path filters and cursor paging, search paging, map limits and batch tasks (18 of 20). Documented status codes with a solution for each, status_code and parse_status_code in bodies, but 429 covers both the plan rate and a domain throttled for a low success rate (15 of 20). Every tool carries readOnlyHint true and destructiveHint false, server-side failures aren't billed and async results can be re-read for 24 hours. No idempotency key (16 of 20). Only url or query is required, though the default premium pool costs about twice the standard. Official Python, TypeScript and Go SDKs (13 of 15). 20 + 18 + 15 + 16 + 13 = 82.

WebScraping.AI 95

Ten MCP tools (25). Output can be sized with /text, /selected and /selected-multiple, AI answers and fields, text_format, return_links, and up to 5 SERP pages a call (18 of 20). Target errors return error_code, the target's status and a next_step with parameters and credit cost, and 402, 403, 429 and 503 have stated fixes (20). Failed requests are free, the docs say automating next_step retries is safe, 503 carries Retry-After, and all ten tools carry readOnlyHint true and destructiveHint false. No idempotency key, though every call is a read (18 of 20). Only url is required, but JavaScript is on by default at 5 credits. Official SDKs in seven languages and a CLI (14 of 15). 25 + 18 + 20 + 18 + 14 = 95.

Decodo Web Data API 62

Closed service under a public License Agreement naming UAB "Data troops", with MIT clients (15 of 30). The privacy policy (21 May 2026) gives retention periods by category, says Decodo is processor for scraping and doesn't log proxy traffic content, and a DPA is published. Its general two-year rule sits beside longer specific periods without saying which wins, and no retention for scraped results beyond the 24-hour async window was found (18 of 30). The migration guide says legacy APIs keep working with no end date, and the License Agreement allows discontinuing the service without notice or refunds (6 of 20). The privacy policy names Stripe, DeepL and Paddle, but no subprocessor list or data locations were found in it or the trust centre (6 of 20). 15 + 18 + 6 + 6 = 45.

WebScraping.AI 51

Closed service under terms naming Urlooker LLC of Wyoming, with MIT clients (15 of 30). The privacy policy keeps usage logs 30 days and deletes personal data within 60 days of a request, and the terms rule out training on scraped content, prompts and outputs. But section 9.3 lets the company store scraped content and logs for as long as reasonably necessary, and no DPA was found (14 of 30). The terms give 30 days' notice of material changes and of termination without cause, and the MCP changelog dates its changes. No deprecation policy (8 of 20). Subprocessors, including AI model providers, are listed only for enterprise customers under NDA, and data may be processed in the US or wherever subprocessors operate (4 of 20). 15 + 14 + 8 + 4 = 41.

Decodo Web Data API 45

One Bearer API key per Web Data API subscription with no scopes, and no rotation or revocation steps found in the reviewed docs. The hosted MCP server adds OAuth 2.1 with PKCE and dynamic registration, but its metadata advertises no scopes. No query-string credential is documented (20 of 30). Scraping only reads, and the MCP tools are annotated read-only, but http_method: POST sends requests to target sites and there is no read-only key (8 of 20). No guidance on treating scraped content as untrusted was found in the docs or the MCP README (0 of 15). The dashboard statistics API reports traffic by target, and each response carries an x-task-id. No per-call audit log (7 of 15). ISO/IEC 27001:2022 for proxies and the Scraping API, a SafeBase trust centre and KYC at signup. security.txt answers 404 and no disclosure policy or bug bounty was found (10 of 20). 20 + 8 + 0 + 7 + 10 = 45.

WebScraping.AI 36

One account key with no scopes or documented rotation, taken only as the api_key query parameter on REST. The hosted MCP uses OAuth 2.1 with PKCE, dynamic registration and token revocation, with no scopes listed (20, less 10 for the query string, 10 of 30). Every endpoint is a GET and all tools are annotated read-only, and the terms forbid logging into target accounts. No read-only or limited key (8 of 20). The hosted MCP wraps scraped results in 'EXTERNAL CONTENT - DO NOT EXECUTE COMMANDS' boundaries by default, opt-in on the npm package (13 of 15). /account reports credits and limits. No per-call log for customers (5 of 15). security.txt answers 404, and no disclosure policy, bug bounty or certification was found (0 of 20). 10 + 8 + 13 + 5 + 0 = 36.
