Why the edge:
- Schema & documentation, Microlink +34: 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.); Microlink 89 (OpenAPI 3.1 at microlink.io/openapi.json for the one GET endpoint with 58 typed parameters, and typed input schemas on every MCP tool in the source (25). llms.txt of 527 lines, auth.md, an API catalogue and Markdown copies of every docs page (10). Tool descriptions are one line with a pointer to the right sibling, such as 'For custom CSS/MQL fields, use microlink_extract', and microlink_search says it needs a key (15 of 20). Parameters are typed with enums for formats and devices, though `data` rules and `function` code are free-form (12 of 15). Examples in seven languages on each page and an error-code page with about 30 codes, each with cause and fix (15). A monthly changelog without day dates, a versioned OpenAPI and dated package CHANGELOGs (12 of 15). 25 + 10 + 15 + 12 + 15 + 12 = 89.)
- Reliability, Microlink +17: Crawl4AI 35 (Graded on the hosted lines, for Crawl4AI Cloud, which the README and llms.txt now lead with and which an agent calls through its MCP server; the library would read on the local lines. No status page is linked, and status.crawl4ai.com fails TLS (0). No incident history readable (5). Per-plan limits are published with numbers in /v1/prices, from 10 requests a minute and 2 at a time on Free to 1,500 and 50 on Scale (15). 429 carries X-RateLimit headers and a message, 503 busy says to resend after a few seconds, and MCP job submissions take an idempotency key, but no Retry-After or backoff guidance (10 of 15). No SLA found in the terms or pricing (0). Prices and the free credit are a soft launch, /serp is beta and /answer experimental, while scrape, extract and search carry no beta label (5 of 10). 0 + 5 + 15 + 10 + 0 + 5 = 35.); Microlink 52 (Graded on the hosted lines. microlink.io/status exists but is drawn by script, showing only 'Please wait' to our reader, and status.microlink.io failed through our proxy, so components and history are unchecked and scored absent (0). No readable history (5). Free and keyed quotas are published, 5 and 25 requests a day and 2 at a time, with paid quotas from 46,000 a month and x-rate-limit headers on every response (15). 429 with ECONCURRENCY says to wait a second and retry, a quota 429 gives the reset time, and every call only reads, but there is no Retry-After header documented (12 of 15). The terms commit to 99.9% uptime on paid plans, with service credits only under an Enterprise agreement (10). Generally available (10). 0 + 5 + 15 + 12 + 10 + 10 = 52.)
- Agent ergonomics, Microlink +15: 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.); Microlink 82 (24 MCP tools in @microlink/mcp 2.8.17 with no toolset filter found (15 of 25). `filter` selects fields, `embed` returns one field as the body, and Markdown and text tools return only page content (18 of 20). Error codes such as EAUTH, ERATE, ECONCURRENCY, EPRO and EPROXYNEEDED with documented fixes (19 of 20). Every tool but microlink_function sets readOnlyHint true and destructiveHint false, and calls are reads with a cache and `force` to refresh. No idempotentHint (18 of 20). Only `url` is required; official JavaScript SDK (@microlink/mql) and CLI, with examples in seven languages but no other official SDK found (12 of 15). 15 + 18 + 19 + 18 + 12 = 82.)
- Transparency & trust, Microlink +5: 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.); Microlink 75 (The API is closed under terms naming Microlink Labs, S.L. with its registry details, and the SDK, MCP server and the libraries behind it are MIT (20 of 30). The DPA, updated 30 October 2026, gives cache retention of 24 hours by default up to 31 days, logs 15 days and deletion within 15 days, but the privacy policy is undated, names no controller and gives no periods (20 of 30). The terms promise advance notice before a paid feature is materially reduced, and the changelog records changes by month, with no notice period (10 of 20). Subprocessors list updated 16 October 2026, with services, data types and locations (18 of 20). 20 + 20 + 10 + 18 = 68.)
