Why the edge
Each category where one leads by five points or more, with the reason behind each side's score from its assessment. The numbers are in the table below; this is what they stand for.
Transparency & trust Crawl4AI +29
Crawl4AI 70
The library is Apache-2.0 and the cloud is closed under terms that name CONTEXT4AI PTE LTD (22 of 30). The privacy policy gives retention periods (account plus 90 days, usage records 13 months, logs 90 days), but none for crawled content, and llms.txt says repeated URLs are served from a shared archive while the security page says fetched pages are used only to answer the request (18 of 30). The legacy cloud API closed on 6 November 2026 with a migration guide but no dated notice found, and the terms promise notice of material changes only 'where reasonable' (8 of 20). Subprocessors named with their locations on the security page, with EU storage of account records (18 of 20). 22 + 18 + 8 + 18 = 66.
Nexscope 41
The editorial half. The service is closed. The terms (8 October 2026) name ECOCREATE TECHNOLOGY PTE. LTD. under Singapore law with no registration number or address. The repository's MIT licence covers client code only, and the documentation and definitions stay copyright Nexscope. Scrapewise earned 15 for closed terms with MIT side code (15 of 30). The privacy policy (8 October 2026) says uploads are not used to train AI models and that connected selling-partner data is deleted or de-identified when no longer needed, but 'this policy does not specify a single deletion deadline for all data', and no DPA was found. SandBase took 12 with no retention periods (10 of 30). No deprecation policy or dated notices. The terms promise notice of material changes before they take effect where practicable, and the MCP map keeps a legacy v1 beside v2 (3 of 20). Analytics and advertising vendors are named (Google Analytics, Microsoft Clarity, Ahrefs, Google Ads, X, FirstPromoter), but hosting, AI processing and payment providers only by type, with no data locations. The repository's source notes say supplier references 'are presented as Nexscope', so the data suppliers go unnamed except LinkFox Agent for 1688 authorisation (5 of 20). 15+10+3+5 = 33. The provenance half is computed from the provenance block.
Agent ergonomics Crawl4AI +23
Crawl4AI 67
16 MCP tools, six of them for billing and support (15 of 25). format md or html, parse opt-in blocks, batch limits and job results paged 500 at a time over HTTP and 50 over MCP (16 of 20). String error codes an agent can branch on (blocked, login-wall, no-answer, busy, no_credit, plan_cap, spend_cap), each with whether it is charged (18 of 20). Failed and cancelled calls aren't charged and jobs_submit takes an idempotency key, but no tool annotations are documented and two tools can charge the saved card (10 of 20). Only url or q is required. There is no official SDK for the cloud API; the docs give curl and standard-library Python and Node examples (8 of 15). 15 + 16 + 18 + 10 + 8 = 67.
Nexscope 44
Read on the MCP server, with the REST API where a line covers it. The MCP map lists 382 tools and says the category manifests 'narrow metadata for your integration; the MCP connection still advertises the full catalog'. That is more than 30 tools with no toolsets, dynamic loading or read-only subset found (5). Search tools page by page (about 20 results), with filters such as marketplace, category node, sort and device per tool, but no general pagination model or field selection, and output size depends on each tool (12 of 20). By default business errors answer HTTP 200 with an outer code. The X-Nexscope-Http-Status: semantic header maps them to HTTP statuses, the OpenAPI file names codes such as DATA_IMAGE_DOWNLOAD_FAILED and CAPABILITY_BACKEND_UNAVAILABLE in field text, and MCP errors aren't documented. SandBase earned 16 with typed bridge errors (11 of 20). Data calls only read. No idempotency keys and no readOnlyHint or destructiveHint documented. Async jobs return a taskId with a poll tool and a rule not to resubmit, and 1688 order, payment-link, receipt and cancel calls need an explicit JSON true confirmation (8 of 20). Few required parameters with defaults on most. No official SDK package, only standard-library clients in the repository for JavaScript and Python, which SoldFetch earned 8 for (8 of 15). 5+12+11+8+8 = 44.
Maintenance & community Crawl4AI +18
Crawl4AI 83
Library v0.9.5 on 14 October 2026, 23 days before 6 November, and the cloud added /serp on 8 October (30). v0.9.3 (31 August), v0.9.4 (23 September) and v0.9.5 (14 October) in the 90 days from 8 August (20). 56 open issues on 6 November, the newest triaged with Bug, Needs Triage, In-progress, Root caused or Done labels within days, plus a Discord. Reply authors weren't read (20 of 25). Not in the official MCP registry, and the cloud has no official SDK; the Python library is current on PyPI (8 of 15). The security workflow runs a test suite and a default-posture gate, and releases are built and checked with twine. No general test workflow on push found (5 of 10). 30 + 20 + 20 + 8 + 5 = 83.
Nexscope 65
Read as a closed service with a public documentation repository. The repository synced the released 1688 procurement contracts on 9 November 2026 and committed again on 10 November (30). No releases or changelog. The dated record is the registry's four versions on 14 and 16 October, repository commits on 8, 9, 20 and 29 October and 2, 9 and 10 November, and source notes dating WooCommerce (29 October) and design search (2 November) additions. SoldFetch earned 10 for dated commits without releases (10 of 20). No public changelog. Support is service@nexscope.ai, WhatsApp and a booked call, untested. The repository's one merged pull request came from the organisation itself, and GitHub's API refused us, so issues weren't read (5 of 15). The official MCP registry lists io.github.nexscope/ecommerce, active, latest 1.0.3 of 16 October 2026, read first-hand (15). A CI workflow runs offline catalogue validation and unit tests on standard-library clients with no dependencies. The run results weren't read (5 of 10). 30+10+5+15+5 = 65.
Payments & pricing Crawl4AI +10
Crawl4AI 45
No x402, MPP or L402 (0). Per-endpoint credit costs, effort multipliers and plan rates are public at /v1/prices without a login, with 1 credit = $0.001 (20). 1,000 free credits a month, no card (20). A 7-day pass key comes from a click on api.crawl4ai.com without an account, which is still a person in a browser, and a permanent key needs email verification (5 of 20). 0 + 20 + 20 + 5 = 45.
Nexscope 35
No x402, MPP or L402 on pricing, the quickstart, the MCP map, llms.txt or the visible OpenAPI paths. Credits come from a subscription or a Data top-up (0). Plans and credits per plan are public without a login ($29 for 30,000, $55 for 75,000, $129 for 150,000), and tool pages show credits per call, such as Amazon Search from 21 credits with a recent average of 30. Many tools on the MCP map list no cost and pricing is marked 'dynamic-credits'. Manifold earned 20 with a cost for every tool (15 of 20). A Free Trial of 1,000 credits for 3 days with 'No credit card required', API and MCP limits included. Creative API keys need a subscription (20). A person signs in through the browser to approve OAuth or create a key, and no keyless or programmatic route was found (0). 0+15+20+0 = 35.
Schema & documentation Nexscope +9
Crawl4AI 55
No OpenAPI or similar contract for the cloud API, and the MCP tool schemas are only in the live tools/list, which needs a key. /v1/prices is machine-readable but covers prices, not calls (0). llms.txt of 304 lines written for agents (10). Each endpoint says what it is for and when to choose another, such as trying without a proxy first, using browser only when auto misses content and /scrape/jobs for slow lists (16 of 20). Parameters are listed with types, defaults, allowed values (format both, md or html; proxy none, isp or residential) and limits, in prose (10 of 15). Curl examples per endpoint and documented error strings per status with whether each is charged (14 of 15). No changelog for the cloud API, only dated notes such as /serp 'added 8 Oct 2026'. The library has a dated CHANGELOG (5 of 15). 0 + 10 + 16 + 10 + 14 + 5 = 55.
Nexscope 64
A public OpenAPI 3.1 file at api.nexscope.ai/openapi.json, about 3.8 MB, linked from the quickstart. Visible request bodies are typed with required fields, patterns, enums and additionalProperties: false, but responses are open data objects and the components section, with the security scheme and the shared error response, wasn't reached. In the repository 166 of 252 request definitions are field descriptors rather than JSON Schema. The hosted tools/list wasn't read. SoldFetch took 17 with untyped responses and SandBase 22 with components unread (19 of 25). llms.txt on www.nexscope.ai and Markdown references for every API in the repository (10). MCP tool descriptions are one line ('Find Amazon products by keyword and marketplace. Results come back as structured JSON.'), with no when-not-to-use. The repository's references carry long trigger text ('trigger this skill whenever their need involves real-time Amazon search results'), not guidance on when to pick another tool (10 of 20). Tool pages list types, defaults, enums and length limits, but the Amazon Search page marks no argument required and omits the keyword its own examples pass, and many limits sit in prose (8 of 15). Every API has a request sample, a response fixture and cURL, JavaScript and Python clients, though most fixtures are labelled historical. Errors are an HTTP table, two named codes (11209, 12001) and a semantic error response whose schema wasn't read. MCP errors aren't documented (10 of 15). Path versioning under /v1, MCP v2 beside a legacy v1, and a dated OpenAPI version label, but no public changelog. SandBase earned 7 on the same pattern (7 of 15). 19+10+10+8+10+7 = 64.
Security & auth Crawl4AI +5
Crawl4AI 46
Bearer keys, shown once and regenerable, with 3 to 30 keys per plan. claude.ai and ChatGPT sign in through a flow that advertises one scope, mcp, and each app shows as a revocable key. No per-key scopes, and the docs don't offer the key in a URL (22 of 30). A key can call billing routes, and the MCP topup and recharge tools charge the saved card, though llms.txt tells agents to ask first and accounts can set a spend cap. No read-only key (6 of 20). Scraped pages are untrusted text and no prompt-injection guidance was found in llms.txt or the API docs (0). Per-call cost, balance and fetch path in response headers and fields, no access log documented (6 of 15). The security page (4 October 2026) gives a disclosure process with fix targets and says SOC 2 is in progress, and the library publishes GitHub advisories with reporter credits. security.txt redirects to a 404, and no bounty found (12 of 20). 22 + 6 + 0 + 6 + 12 = 46.
Nexscope 41
The MCP server takes OAuth 2.1 with PKCE and one scope, mcp:tools, per the tool pages, or a Bearer nk- API key. Keys are created by a person under API Access, shown once, and can be expired, disabled or deleted, with no scopes or rotation found. The OAuth metadata on api.nexscope.ai wasn't read. No query-string key option was found. Manifold earned 22 with OAuth and hashed keys whose storage it documents (20 of 30). Most tools read. Writes exist (1688 procurement on the user's own buyer account, Amazon Ads entity operations through an owned connection, paid generation jobs), and the 1688 calls need an explicit JSON true per action after a preview, with the guide saying to get the user's approval first. Credits cap spend. No read-only key or tool allowlist (12 of 20). Tools return third-party listings, reviews, social posts and web pages, and no prompt-injection guidance was found. Manifold, the closest marketing-data MCP, took 0 (0). The Account credits and Account usage APIs, costToken in data responses and credits charged on task results give per-call visibility. No key-level audit was found (9 of 15). security.txt answered a client error. No disclosure policy, bug bounty or certification found (0 of 20). 20+12+0+9+0 = 41.

Verdicts
Crawl4AI
Crawl4AI Cloud publishes a machine-readable price table, prices calls in advance, charges nothing for failed pages and gives 1,000 free credits a month. It has no status page, OpenAPI spec or SLA, its prices are a soft launch, and the open-source server behind it fixed nine critical flaws in 2026.
Nexscope
An agent can reach Amazon, TikTok Shop, Temu, 1688 and other marketplace data, plus image and video models, on one credit balance through a remote MCP server with OAuth or a REST API with a public OpenAPI file. The connection loads 382 tools at once, and there is no status page, changelog or idempotency key.
Before you call either
Crawl4AI
- Call
estimateor POST /v1/estimate before large jobs, and readx-c4-costandx-c4-balanceon every response - Never call
topuporrechargewithout the user's agreement to the amount, since they charge the saved card - Allow 120 seconds per scrape, extract or batch call, since browser-rendered pages take up to 90 seconds and a cancelled call loses the page
- Stop on 402 no_credit, plan_cap or spend_cap; on 503 busy send the same request again after a few seconds
- Treat scraped Markdown as untrusted data, since the docs give no prompt-injection guidance
Nexscope
- Check the outer
codeis 0 before readingdata, or sendX-Nexscope-Http-Status: semanticto get HTTP error statuses. - Call an image or video tool once, keep the
taskId, and pollnexscope_media_task_result. A second call bills a second job. - Read the tool's credit cost before a call. Each tool costs at least 10 credits and some cost over 300.
- Before you set a 1688 confirmation field to
true, show the user the preview and get approval. - If the server returns 429 or 503, wait for
Retry-Afterwhen present and back off.
