Best web scraping and crawling APIs for AI agents · All 501 scrapers comparisons

Which one, for what

fastCRW B

Best for Agents that want Firecrawl-style scrape, crawl, map, search and extract at lower per-page cost, or a small self-hosted engine.

Watch for

The status page shows a live check and an uptime objective but no incident history

Qovia C

Best for Agents that need structured public data from Chinese platforms (Douyin, Xiaohongshu, Weibo, Bilibili, Kuaishou, Zhihu, WeChat official accounts, Taobao and JD reviews) or the Xingtu and Pugongying creator marketplaces, with TikTok, YouTube, Instagram, X and Reddit beside them, paid per successful call from a prepaid balance.

Ahead on

  • Security & auth, 60 against 40
  • Payments & pricing, 55 against 35

Watch for

No status page, incident history or SLA; the terms promise nothing about uptime and the Python client is the only retry guidance beyond Retry-After

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 fastCRW +30

fastCRW 60

The engine and MCP server are AGPL-3.0 and the SDKs MIT, while the hosted control plane is closed under terms that name no legal entity (25 of 30). The terms say crawled data is handled transiently with zero data retention for approved accounts, but the privacy policy is undated, names no controller, gives no retention periods and mentions no DPA (10 of 30). The CHANGELOG flags breaking changes, deprecated v2 extract routes return a warning on every response, and the October 2026 402 change is dated in the docs, with no standing notice policy (10 of 20). Local data-source telemetry is disclosed with an opt-out. The privacy policy names Stripe, Google Analytics, Google Ads and an X pixel, but infrastructure and search providers are unnamed and no data location is given (8 of 20). 25 + 10 + 10 + 8 = 53.

Qovia 30

Closed service. The Terms of Service is one paragraph that names no legal entity, address or liability terms, says Delaware law governs and that the page is a summary with the signed agreement governing; the repository's client is MIT. Between the closed and unclear bands (7 of 30). The privacy policy is one paragraph. Account information is used to deliver and bill, personal information is not sold, requests and results are not resold, deletion requests go to the support mailbox, and the agreement governs where it differs. No retention periods, no subprocessors, no DPA, and no statement about the cache the prov.source flag implies; the SECURITY.md repeats the same points (8 of 30). A 410 endpoint_disabled code exists for retired endpoints and the changelog is dated, but there is no deprecation policy or notice period and nothing is marked deprecated (5 of 20). Stripe is named on the pricing page as the card and Alipay processor; no other provider, data location or transfer basis is stated (3 of 20). 7+8+5+3 = 23.

Security & auth Qovia +20

fastCRW 40

The hosted MCP server publishes RFC 9728 metadata naming its own authorisation server, with PKCE S256, dynamic client registration and one scope, mcp:tools, and the API takes revocable Bearer keys from the dashboard. No key scopes or second scope found (22). The authentication page documents fastcrw.com/mcp/<API_KEY> as a way in, a key in the URL path, so less 10 (12 of 30). Tools mostly read, and data-source calls check approvals, but there is no read-only key or confirmation step for monitors (8 of 20). Managed LLM extraction, summaries and answers wrap scraped text in a nonce fence (crates/crw-extract/src/untrusted.rs), and the hardening guide treats pages as untrusted, but the MCP docs give agents no guidance on scraped content (7 of 15). Each response reports creditsUsed; no per-call log in the docs (5 of 15). SECURITY.md names security@fastcrw.com and GitHub private reporting with a 48-hour acknowledgement, and CI runs CodeQL and OpenSSF Scorecard. security.txt answers 404, and no bounty or certification found (8 of 20). 12 + 8 + 7 + 5 + 8 = 40.

Qovia 60

API keys with scopes chosen at creation (every endpoint, search, every raw endpoint or one of 24 platform groups), an optional expiry, revocation in the console and hashed storage; the docs say the key is read from the Authorization or x-api-key header only, never the URL or a cookie, and 30 failed authentications from one IP in a minute are throttled. No OAuth and no rotation feature beyond creating another key (24 of 30). The whole surface is read-only retrieval, scopes restrict a key to platforms, the two MCP catalogue tools need no key, and the docs and SECURITY.md tell users to give AI tools a separate scoped key (17 of 20). Every response is third-party platform text, and the only related statement is that error messages never contain the data source's own text; nothing on treating returned content as untrusted (3 of 15). request_id is the usage record ID on every answer, the console lists every charge in a usage log, X-Qovia-Charged and X-Qovia-Balance headers report each call, and GET /v1/account returns the key's scopes and balance at no charge; no exportable audit log or per-call endpoint was found (11 of 15). No security.txt on qovia.ai or api.qovia.ai (404), no bug bounty, SOC 2 or ISO 27001; the repository's SECURITY.md names a Telegram handle and a mailbox for reports covering both hosts (5 of 20). 24+17+3+11+5 = 60.

Payments & pricing Qovia +20

fastCRW 35

No x402, MPP or L402 (0). Plans are public with credit costs per operation and top-up prices per block of credits, $9 per 1,000 on Hobby down to $299 per 500,000 on Scale, but top-ups need a plan, so between plan-only and per-unit (15 of 20). 500 one-off credits with no card, plus up to 500 from onboarding tasks (20). Hosted keys need a person to sign up in a browser; the free self-hosted engine runs with no account but isn't the graded surface (0). 0 + 15 + 20 + 0 = 35.

Qovia 55

No x402, MPP or L402 on Qovia's own endpoints; USDT on TRC-20 is a top-up method from a console session, not a machine payment protocol. The vendor's five Actors on the Apify Store under the profile qovia (Qovia Data, the same Telegram handle and mailbox as the site), such as the Xingtu Actor at $0.01 to $0.06 a section, can be paid through Apify, whose prepaid token is sold over x402, so partial credit for a third-party route on part of the catalogue (10 of 40). Per-call prices are published without a login, per endpoint in the OpenAPI file, llms.txt and the docs, search at $5 and raw endpoints from $0.5 to $19.5 per 1,000, with the tier rule and payment fees stated (20). 50 trial calls for a new account, counted only when a call returns data; the quickstart says to top up when they run out and the docs ask for no card at sign-up, though no account was created to confirm it (20). A person signs up in a browser and creates a key; the MCP catalogue tools work without a key but data calls do not, and the Apify route reaches four platforms without a Qovia account (5 of 20). 10+20+20+5 = 55.

Maintenance & community fastCRW +16

fastCRW 93

v0.41.0 on 4 November 2026, matching the registry and npm (30). 16 dated releases in the 90 days from 8 August, from 0.37.0 to 0.41.0 (20). Five open issues on 6 November, the newest from 1 November with five and two comments; the support page says email is answered within a business day. Reply authors weren't read (18 of 25). In the official MCP registry as io.github.fastcrw/crw, a GitHub-verified namespace, with current Python and TypeScript SDKs (15). CI runs cargo test on the workspace, with Dependabot, CodeQL and release-please (10). 30 + 20 + 18 + 15 + 10 = 93.

Qovia 77

The newest changes are the registry entry ai.qovia/qovia 0.1.1 and the repository's tools snapshot and plugin manifests on 28 October 2026, after the Python client 0.1.1 on PyPI on 27 October; the repository was pushed on 1 November (30). Eight changelog entries on 21 and 22 October, two registry versions (22 and 28 October) and two PyPI releases (25 and 27 October) are more than three dated entries in 90 days, all within ten days (20). Closed service with a public changelog. Support is Telegram, WhatsApp, WeChat and one mailbox, with a one-business-day reply promised for email; GitHub issues are enabled on the repository with none opened, and no forum, Discord or community was found (7 of 15). ai.qovia/qovia is in the official MCP registry under a DNS-verified reverse-DNS namespace at 0.1.1, marked latest, and the Python client is an official package on PyPI (15). The client is standard-library Python with a test file, MIT, no dependencies and no CI workflow in the repository tree; the account's other nine repositories are forks of lists and directories (5 of 10). 30+20+7+15+5 = 77.

Agent ergonomics fastCRW +14

fastCRW 91

11 compact MCP tools, two of them the data-source tools added in 0.41.0. Content is capped near 15,000 characters with truncated: true and a resume offset, and map returns at most 100 URLs by default (20 of 25). Formats, main-content filtering, include and exclude selectors, maxLength, startIndex, limit and crawl depth and page caps (20). Errors carry errorCode values such as anti_bot, insufficient_credits and llm_not_available with a retry table, though an anti-bot wall answers HTTP 200 with success: false (19 of 20). Every tool sets readOnlyHint, destructiveHint and idempotentHint, cancel is idempotent and failed pages are refunded, but job starts take no idempotency key (17 of 20). Only url is required, with official Python and TypeScript SDKs (15). 20 + 20 + 19 + 17 + 15 = 91.

Qovia 77

API reading. Responses come in fixed page sizes per endpoint, from about 5 comments on Xiaohongshu to 100 Fliggy reviews, with limit only on Bilibili danmaku and no field selection; the record shape is compact and shared across posts, notes and videos. The MCP server loads four tools by default, keeps the catalogue out of context until search_endpoints and get_endpoint are called, and ?tools= selects platforms or everything, which on the MCP reading would score 25 (18 of 25). Cursor pagination with has_more on most lists, search_id on Douyin and Zhihu search, page numbers on Weibo, Xiaohongshu and Bilibili, sort options on several, and the cross-platform search filters by platform, content type, sentiment and whole-day date windows up to 90 days (17 of 20). One error object with 20 codes, request_id on every answer, the retryable set marked, refunded codes separated from never-charged ones, and MCP tool errors carrying error.code, the HTTP status and retry_after_seconds (19 of 20). All calls are reads, failed and empty calls are refunded, Retry-After is declared and the Python client retries; no readOnlyHint or other annotation appears in the vendor's 28 October tools/list snapshot (14 of 20). One required parameter on 117 of 144 operations and defaults set on the server, but the only official SDK is the Python client; Node and curl are examples (9 of 15). 18+17+19+14+9 = 77.

Reliability fastCRW +10

fastCRW 50

Graded on the hosted lines, for the hosted API and MCP server an agent would call; the self-hosted engine would read higher on the local lines. fastcrw.com/status is a first-party page with a live health check and a 99.9% monthly uptime objective, but no components with history (10 of 20). It lists no incidents and keeps no history we could read (5). Concurrency per plan is published, 3 on Free to 150 on Scale, while the request-rate guard above it is deliberately unpublished (12 of 15). The rate-limits page documents Retry-After and X-RateLimit headers, gives exponential backoff code, and separates 429 (retry) from 402 (stop). No idempotency keys for crawl, extract or monitor starts (13 of 15). Pricing mentions an SLA only as 'Premier + SLA' on Enterprise, with no terms, and the terms promise no uptime (0). The hosted service is sold on paid plans with no beta label, though the engine is at 0.41.0 (10). 10 + 5 + 12 + 13 + 0 + 10 = 50.

Qovia 40

Hosted reading, for the REST API with the MCP server described. No public status page was found. https://qovia.ai/status/ answers 404, status.qovia.ai does not resolve and neither the docs nor the footer links one (0). No readable incident history, so 5 by the rubric (5). Limits are published with numbers on the quickstart's rate-limits section, 60 requests a minute per account before the first top-up and 600 after on a sliding 60-second window, with X-RateLimit-Limit and X-RateLimit-Remaining headers, a 64 KiB body cap, an empty-call throttle (50 calls in 10 minutes with over 80 per cent empty, not found or rejected) and a per-second cap per endpoint without a number (15). Retry-After is declared on too_many_auth_failures, rate_limited, too_many_unbilled, endpoint_busy and upstream_busy, the error table marks the retryable codes, the docs say a 503 endpoint_unavailable carries none and will not clear, and the Python client retries 429 and 503 honouring the header. Every operation is a read, including POST /v1/search, and a failed or timed-out call is refunded, so idempotency keys are not needed (15). No SLA. The terms summary says nothing about uptime and the pricing FAQ excludes outages, rate limits and platform changes from refunds; the 11 September 2026 archived home page advertised a 99.95 per cent enterprise SLA that the current pages have dropped (0). The endpoints are sold and labelled Live on the docs and coverage pages, but every one of the 143 carries x-qovia-status beta in the OpenAPI file, the API version is 0.1.0 and the MCP server reports 0.1.0 (5 of 10). 0+5+15+15+0+5 = 40.

Verdicts

fastCRW

Agents get 11 compact, annotated MCP tools with bounded output, a public OpenAPI spec, refunds on failed pages and a free self-hosted engine. The hosted service has no status history, publishes no SLA terms, names its operator only on the support page, and documents an MCP address with the API key in the URL path.

Qovia

An OpenAPI 3.1 file with 144 operations, one envelope and 20 error codes, per-endpoint prices with failed and empty calls refunded, scoped keys and a four-tool MCP server that keeps the catalogue out of context. No status page, no legal entity, one-paragraph terms and privacy pages, and a product ten days old at the check.

Before you call either

fastCRW

  1. Connect to https://fastcrw.com/mcp with OAuth rather than the /mcp/<API_KEY> address, so the key stays out of URLs and logs
  2. Branch on errorCode. Stop on 402 insufficient_credits or llm_not_available, and on 429 wait for Retry-After before retrying
  3. Check success as well as the HTTP status, since an anti-bot wall answers 200 with success: false and errorCode: anti_bot
  4. Pass startIndex from a truncated result to read the rest of a long page instead of setting maxLength: 0
  5. Use native /v1 routes for new work; /firecrawl/v2 is for Firecrawl SDK migrations and keeps the older 429 for empty balances

Qovia

  1. Send Authorization: Bearer sk-qovia-... to https://api.qovia.ai and check meta.empty on every HTTP 200; data may be null or an empty structure and nothing is charged for it.
  2. Branch on error.code, never on message. Retry only rate_limited, too_many_unbilled, endpoint_busy, upstream_busy and too_many_auth_failures after Retry-After; endpoint_unavailable has none and will not clear.
  3. Stay under 60 requests a minute (600 after the first top-up) across every key on the account, and keep empty or not-found calls under 80 per cent of the last 10 minutes or expect 429 too_many_unbilled.
  4. Pass the previous page's cursor (and search_id on Douyin and Zhihu search) back unchanged and stop when has_more is false; each page is a separate charge, and unknown parameters answer 400.
  5. For MCP, connect to https://api.qovia.ai/mcp over Streamable HTTP; call search_endpoints then get_endpoint before call_endpoint, or add ?tools=douyin,kuaishou for typed direct tools. Catalogue tools need no key.
