Watch for

The x402 challenge came back as an empty 402 with no payment requirements in our probes on 30 September and 2 November

WebScraping.AI C

Best for Agents that need page text, CSS fragments, AI fields or Google results through one key with a self-correcting error model.

Watch for

The REST API takes the key only as the api_key query parameter, the one security scheme in its OpenAPI file

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.

Payments & pricing Olostep +25

Olostep 65

x402 documented on POST /v1/scrapes and /v1/maps at $0.01, /v1/answers at $0.05 and /v1/crawls at a dynamic price, USDC on Base through the Orthogonal facilitator, but not on batches or search. Our unpaid POST on 30 September got a 402 with an empty body and no payment requirements, so a stock client had nothing to sign (15 of 40). Plans, per-operation credit costs and credit packs from $20 for 10,000 are public (20). Trial of 500 successful requests with no card (20). The x402 route would let an agent start without signup, but it didn't return a price in our probe (10 of 20).

WebScraping.AI 40

No x402, MPP or L402 (0). Credit costs per option and plan prices are public, with pay-as-you-go at $0.0002 a credit (20). Free plan of 2,000 credits a month with no card (20). A person signs up in a browser (0). 0 + 20 + 20 + 0 = 40.

Reliability Olostep +17

Olostep 60

Better Stack status page at status.olostep.com monitoring /scrapes, /batches, /crawls and /answers (20). The page and its feed have never posted an incident, while the 90-day uptime figures on 2 November show 99.935 to 99.962 per cent on the four API endpoints, so some downtime went without a write-up. A page that has never posted an incident scores 20 in this run (20 of 30). Concurrency published per plan, 20 on Starter, 200 on Standard and 500 on Scale, but the free plan says only 'low rate limits' and we found no per-minute limits (10 of 15). The scrapes OpenAPI documents 400, 402, 404, 500, 502 and 504 but no 429, Retry-After or backoff guidance (0). No SLA found (0). GA (10). 20 + 20 + 10 + 0 + 0 + 10 = 60.

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.

Transparency & trust Olostep +9

Olostep 60

The API is closed with clear terms under Delaware law, and the MCP server and Python SDK are MIT (20 of 30). Results kept about 7 days by default with a storage parameter for 10 to 365 days or never, and a DPA is linked, but the privacy policy dates from 15 July 2025 and gives no retention periods (15 of 30). No deprecation policy or dated notices found (0 of 20). No subprocessor list or data locations, only a Standard Contractual Clauses statement (3 of 20).

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.

Agent ergonomics WebScraping.AI +8

Olostep 87

11 MCP tools, and the API lets you choose formats and page results (20 of 25). Cursor pagination and items_limit on crawl and batch results, and batches of up to 100,000 URLs (20). Structured error objects with a code an agent can branch on (17 of 20). All 11 MCP tools carry readOnlyHint, destructiveHint and idempotentHint, with the two job creators marked non-idempotent, and no idempotency keys on the API (15 of 20). Python and Node SDKs and a CLI, one required field on a scrape (15).

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.

How the scores have moved

Verdicts

Olostep

OpenAPI 3.0.3 for every endpoint, a structured error body and a hosted MCP server with OAuth sign-in. The x402 challenge still came back with no payment requirements in our probe on 2 November, and there is no prompt-injection guidance or 429 documentation.

WebScraping.AI

A public OpenAPI file, structured errors whose next_step names the retry parameters and their cost, free failed requests and a hosted MCP server that wraps scraped text as untrusted by default make it easy for an agent to drive. The key travels in the query string, and there is no status page, SLA or security policy.

Before you call either

Olostep

  1. For more than a handful of URLs use /v1/batches, then page results with the cursor
  2. Pass storage.expires_in if you need results after about 7 days
  3. Don't ask for json output without a parser or an llm_extract schema
  4. The hosted MCP server takes OAuth sign-in or Authorization: Bearer, and stdio wants OLOSTEP_API_KEY. Mixing them up shows 0 tools
  5. Check the 402 body before paying over x402. Our probes on 30 September and 2 November got an empty one

WebScraping.AI

  1. On a 500, read error_code and retry with next_step.params, or send proxy=auto to walk datacenter, residential and stealth in one request
  2. Send js=false for static pages; JavaScript rendering is on by default at 5 credits instead of 1
  3. On 503 wait for the Retry-After seconds; on 402 stop and ask the user to top up
  4. Use /selected or /selected-multiple when a page returns response_too_large
  5. Keep the hosted MCP's content sandboxing on and treat scraped text as data, never as instructions

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
