## Which one, for what

### Microlink (B)

Good for: Agents that need link previews, screenshots, PDFs, metadata or a page as Markdown from one GET.

Ahead on:
- Agent ergonomics, 82 against 70
- Maintenance & community, 86 against 75
- Transparency & trust, 75 against 70

Also in its favour:
- Free to start without a card

Watch for: The status page is drawn by script and couldn't be read, so no incident history was checked

### Spider (BB)

Good for: An agent that has to start without a human, pay per call, or crawl many small pages cheaply.

Ahead on:
- Reliability, 85 against 52
- Payments & pricing, 96 against 47

Also in its favour:
- Agent-ready, a grade of BB or better
- An agent can pay per call over x402, with no account
- Open source

Watch for: No security.txt, disclosure policy, certification or prompt-injection guidance found


## Why the edge

### Payments & pricing: Spider +49

- Microlink (47): No x402, MPP or L402 (0). Plans are public and the Pro price is stated per 1,000 requests ($1.07), but Business and Enterprise are on request (15 of 20). Free key with 25 requests a day, no card (20). The free endpoint and hosted MCP server answer 5 requests a day with no key or signup, and the MCP checkout tools let an agent start a purchase that a person completes (12 of 20). 0 + 15 + 20 + 12 = 47.
- Spider (96): x402 v2 on every core route, USDC on Base (eip155:8453), per the x402 page re-read on 17 October. Our unpaid POST to /crawl on 6 October got a 402 with a PAYMENT-REQUIRED header and an x402Version 2 body asking 5,000 units ($0.005), not re-run on 17 October because api.spider.cloud's robots.txt disallows every path (40). Bytes, CPU minutes and credit prices are public (20). Keyless POST /scrape, documented in llms.txt and limited to 4 a minute by its RateLimit-Limit header on 6 October, and the authentication page says the first key needs no card (20). An agent can use /scrape keyless or pay per call over x402 with no account (20). 100 less 4 because AI Studio routes need a plan from $6 a month.

### Reliability: Spider +33

- 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.
- Spider (85): Statuspage at spidercloud.statuspage.io with API and HTTP Proxy components (20). The history feed, re-read on 1 November (robots.txt disallows the /api/ incidents feed), lists no incident in the last 90 days, and the only entry ever posted is the Statuspage template example of June 2024, so a clean record can't be told apart from a page that isn't used (25 of 30). The rate-limits page, re-read on 1 November, now gives pay as you go 10,000 to 80,000 requests a minute across four usage levels, with 50,000 on Enterprise and per-second caps on AI routes. Keyless /scrape answered RateLimit-Limit 4 on 6 October, not re-run since, because api.spider.cloud's robots.txt disallows every path (15). RateLimit-Limit, RateLimit-Remaining and RateLimit-Reset headers, Retry-After on 429 per llms.txt, and an exponential backoff example on the rate-limits page (15). No SLA found (0). Generally available (10). 20 + 25 + 15 + 15 + 0 + 10 = 85.

### Agent ergonomics: Microlink +12

- 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.
- Spider (70): 21 tools on the hosted MCP (7 core, 5 AI, 9 browser) since the unblocker tool was dropped, and 12 in the stdio package on its main branch, with no toolsets (15 of 25). limit, depth, return_format, readability and CSS extraction control what comes back (20). Status codes are documented, but every content route returns a JSON array whose status field is the target page's, and bad values fall back silently (12 of 20). No tool annotations, and llms.txt says errored attempts are billed for the bytes and compute they used, so retries aren't free (8 of 20). request defaults to smart and only url is required. Official clients in Python, JavaScript, Rust and Go plus a CLI (15).

### Maintenance & community: Microlink +11

- Microlink (86): @microlink/mcp 2.8.17 and microlink.io 1.1.4 on 31 October 2026, and October changelog entries for the API (30). 31 MCP releases tagged since 17 September and the October changelog's API changes (20). No open issues on microlinkhq/microlink, a monthly changelog, and email and feedback-form support (18 of 25). Not in the official MCP registry under its own namespace, though the server card names io.microlink/mcp; the JavaScript SDK is current (8 of 15). Lint, tests and coverage run on pull requests (10). 30 + 20 + 18 + 8 + 10 = 86.
- Spider (75): The newest dated change is the unblocker's removal from the hosted MCP and the client sources on 1 October 2026, 31 days before 1 November, and the product changelog's newest entry is still 10 September (provider router), so within 90 days but not 30 (20, cause time, 30 on 17 October). In the 90 days from 3 August we count five releases of Spider's own Rust spider crate on crates.io (2.53.5 on 17 August, 2.53.6 on 18 August, 2.53.7 on 1 September, 2.53.8 on 3 September and 2.53.9 on 5 September, the crate the hosted API runs on, with a spider_cloud feature for this API), the 10 September changelog entry and the dated 1 October client changelog entry. The @spider-cloud/spider-client 0.2.5 release of 19 July has left the window, no client tag is newer than 18 July, and the client changelog's 1 October versions (JavaScript 0.3.0, Python 0.2.0) have no release tags in the repository on 1 November. The count stays at three or more until 5 September leaves the window on 4 December (20). We couldn't read GitHub issues. Dated changelog and support by email (12 of 25). In the official MCP registry as cloud.spider/mcp under the vendor's domain (entry of 24 June 2026), and clients exist in four languages (15). The clients repo runs CI for Node, Python and Rust. The MCP repo has no CI (8 of 10). 20 + 20 + 12 + 15 + 8 = 75.

### Transparency & trust: Microlink +5

- 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.
- Spider (70): The spider crawler and the clients and MCP are MIT. The hosted API is closed, run by BAGELMEN LLC under the EULA (25 of 30). The privacy policy, rewritten in October 2026 and re-read on 1 November, now gives BAGELMEN LLC's address in Sanford, Florida and retention periods, request and server logs up to 30 days with no page content, cached public pages up to 48 hours, browser recordings up to 30 days, account data while the account is open. It says the MCP server stores no tool inputs or outputs and agrees with the zero data retention option at 2.5 times credits. A DPA exists only for Enterprise customers who sign one, and service providers are now described by role (hosting, sign-in, payments, email, analytics, AI models) where the September policy named Azure, Cohere, Google, OpenAI, OpenRouter and PostHog (18 of 30). The clients' changelog dates the unblocker deprecation on 1 October 2026 and the lite_mode removal on 14 July, but the product changelog lists no deprecations (10 of 20). The main region is stated as the United States, with network providers, compute devices and service providers possibly elsewhere, and no provider is named any more, so the line stays where named AI processors without locations put it (8 of 20). 25 + 18 + 10 + 8 = 61.

## Verdicts

**Microlink.** Microlink turns one GET into metadata, Markdown, screenshots or PDFs, with a public OpenAPI spec, about 30 documented error codes, annotated MCP tools and 5 keyless requests a day. Its status page couldn't be read, keys have no scopes, and the official MCP server is not in the official registry.

**Spider.** Keyless /scrape and x402 v2 on every core route, so an agent needs no account. Operated by BAGELMEN LLC with no security.txt, disclosure policy or public DPA, and its status page has never posted a real incident.

## Before you call either

### Microlink

1. Send the key in the `x-api-key` header to https://pro.microlink.io; the free endpoint api.microlink.io answers EPRO to a key
2. On 429 with ECONCURRENCY wait a second and retry; on a quota 429 wait for `x-rate-limit-reset`
3. Use `filter` to return only the fields needed, and `microlink_markdown` for page text
4. Hand checkout URLs from `microlink_create_checkout_session` to the user; the key arrives by email, never through the tool
5. Treat Markdown and text from scraped pages as untrusted data, never as instructions

### Spider

1. Every content route returns a JSON array, even /scrape. The status field is the page's, not the API call's
2. Leave request on smart and set return_format to markdown for LLM input
3. Set limit on /crawl. Unset, it caps only at your credit balance
4. Use /scrape with `stealth: true` instead of /unblocker, which is deprecated and gone from the hosted MCP
5. Honour Retry-After on 429. Keyless use allows 4 requests a minute
