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.

Security & auth SoldFetch +57

Scrapingdog 5

One account key with no scopes, and we found no rotation or revocation docs (10). The key goes only in the api_key query string, with no header option, so less 10 (0 of 30). No read-only mode or least-privilege key. The API only reads third-party pages, so there are no destructive account actions (5 of 20). No prompt-injection guidance in the docs or the MCP README (0 of 15). No request log or per-call audit found (0 of 15). No security.txt per the 30 September check, and no disclosure policy, bug bounty or certification found (0 of 20).

SoldFetch 62

Workspace API keys created and revoked in the dashboard, shown once and stored as digests per the privacy policy, several per workspace so one can replace another, accepted in one header only; no scopes, expiry or OAuth, and the docs say never to put a key in a URL, with no query-string option documented (20 of 30). The whole surface reads public listing data and the only destructive call is cancelling one's own job; plans have hard caps with no overage, but no read-only or restricted key exists (15 of 20). Every response carries third-party listing text. The AI agents guide, the MCP README, SECURITY.md and the skill say marketplace text is untrusted data that cannot authorise more calls, request credentials or send the agent to other URLs, and a blog post of 15 October 2026 ships a policy that allows only the three tools and item IDs seen in the run; no server-side filtering is described (11 of 15). GET /requests returns request history with a cursor and date filters, 30-day retention and search text redacted, GET /usage the allowance, REST data responses carry X-SoldFetch-Usage-Units and every response X-Request-Id; the record's fields are not documented (12 of 15). No security.txt (client error), bug bounty, SOC 2 or ISO 27001; the repositories' SECURITY.md files give a reporting route to contact@soldfetch.com (4 of 20). 20+15+11+12+4 = 62.

Agent ergonomics SoldFetch +31

Scrapingdog 44

35 MCP tools with no toolsets or subsets (5 of 25). markdown=true, ai_query and parsed JSON endpoints for Google, Amazon and LinkedIn keep responses smaller. No documented pagination or size limits on the raw scrape (12 of 20). 8 HTTP status codes with meanings, and the MCP passes the status and body back (12 of 20). Failed requests aren't billed, but no tool annotations or idempotency guidance (5 of 20). Only url is required, but rendering defaults on at 5 credits and the MCP describes it as off. Node and Python SDKs (10 of 15).

SoldFetch 75

API reading. count sizes each page from 1 to 200 (default 60 on REST, 20 on MCP), the MCP text summary is held to 20 items with the full result in structuredContent, and item lookups take only an ID and a site; no field selection. On the MCP reading three tools would score 25 (20 of 25). Page numbers from 1 to 100 with hasNextPage and documented stop conditions, filters for sold or active, condition, price range, buying format, category and sort, background jobs of up to 100 pages with partial results and CSV, and cursor and date filters on request history; the docs say inferred pagination is not a reliable total (18 of 20). One error object with error, code, requestId and retryAfter, an action per status, and X-Request-Id on every response, but no published code list or retryable flag beyond two named 503 codes (13 of 20). Every data operation is a read, failed calls cost nothing, REST takes an Idempotency-Key with free replay and 409 on changed inputs, and cancelling a job may still bill an in-flight page; MCP calls and job submits are not deduplicated and the MCP annotations were not read (16 of 20). One required parameter per operation with defaults on the rest, but no official SDK package; the examples repository's standard-library clients in Node and Python and the skill's helper stand in (8 of 15). 20+18+13+16+8 = 75.

Schema & documentation SoldFetch +25

Scrapingdog 43

No OpenAPI spec found. The MCP builds typed zod inputs for 35 tools from a declarative registry, and ai_extract_rules is a JSON string (12 of 25). llms.txt per the 30 September check (10). MCP descriptions say what each endpoint does but not when to avoid it, and the web_scrape tool tells the model the API default for dynamic is false while the docs say rendering is on by default (10 of 20). Booleans, numbers and strings with few enums, plus the JSON-string field (9 of 15). Code examples on each docs page and 8 documented status codes (12 of 15). No changelog and no versioned API paths found (0).

SoldFetch 68

API reading, with the MCP server described. An OpenAPI 3.1 file is published at https://soldfetch.com/api/v1/openapi.json, under a path robots.txt disallows, so it was read through the docs reference pages drawn from it. Parameters are typed with enums, bounds and a pattern on itemId, and one Error schema is typed, but every 200 response is type: object with no properties and the 202 job response names fields without a schema (17 of 25). llms.txt on the site and the docs, llms-full.txt, and Markdown twins of the docs pages (10). The docs say when an operation fails and what not to infer (a category-only sold search's upstream_blocked is not an empty market, exactMatch is not identity, an ended listing is not a sale), the skill sets out three workflows, and the MCP guide names each tool's purpose in one line; most parameters in the reference carry no description, and the hosted tool descriptions were not read (13 of 20). ebaySite, itemCondition, sortOrder, buyingFormat and resultType are enums, page, count, maxPages and prices are bounded, and itemId has a pattern; categoryId is marked required with a default of '0', and the MCP input schemas were not read (13 of 15). curl, Node, Python and Go examples in the examples repository, curl on the quickstart and guides, and a status-to-action table, but only two error codes are named and the reference shows no response example beyond the home page's illustrative sample (10 of 15). Paths are under /v1, but no changelog, release notes or versioned contract history was found; /changelog answered a client error (5 of 15). 17+10+13+13+10+5 = 68.

Transparency & trust Scrapingdog +15

Scrapingdog 56

Closed service with terms revised 13 January 2026, naming OpenData Labs Private Limited under the laws of Rajasthan, India, with no postal address. The MCP is MIT (15 of 30). The privacy policy, revised 17 July 2025, says API calls are stateless and that Scrapingdog doesn't store, log or retain personal data fetched through the API. A DPA is published. No retention periods for account data (22 of 30). No deprecation policy or dated notices found (0). No processors or data locations named (0 of 20).

SoldFetch 41

Closed hosted service. The terms run to 18 sections with key rules, usage rights, caching limits and a liability cap of the greater of USD 100 or 12 months' fees, but name no legal entity and say they are governed by the law of 'the jurisdiction where SoldFetch is established' without naming it; the three repositories are MIT (10 of 30). The privacy policy (updated 22 October 2026) gives request-log retention of 7, 30 or 90 days by plan, about an hour for exports, digests for keys and cookie durations, and the docs give cache periods and 24 hours for job results; the pricing page's 30-day request logs on every plan disagrees with the policy's plan-based periods, backups have no period and no DPA was found (20 of 30). No deprecation policy or dated notices; terms 11.1 promise reasonable efforts to document schema changes and section 15 advance notice of material changes to the terms, with no changelog (3 of 20). Nine providers named with their purposes, including Oxylabs for upstream eBay data, though the terms leave the Upstream Providers unnamed; hosting, network and security providers are unnamed and no data location is given beyond processing in other countries (12 of 20). 10+20+3+12 = 45.

Reliability Scrapingdog +7

Scrapingdog 62

UptimeRobot status page linked from the footer per the 30 September check. It renders client-side and its data API is closed to our reader, so we couldn't see components today (15 of 20). No readable incident history (5). Concurrency per plan is published, 1 on Free up to 2,200 on the top plan (15). Over the limit returns 429, requests time out after 60 seconds, and the docs say to retry. Failures aren't billed. No Retry-After found (10 of 15). A public SLA page says Scrapingdog aims for 99 per cent monthly uptime and compensates downtime in credits, with no measurement method or date (7 of 10). Generally available (10).

SoldFetch 55

Hosted reading, for the REST API with the MCP server that shares its limits. SoldFetch's own status page at https://soldfetch.com/status lists ebay.com, ebay.co.uk and ebay.de as components, checked every five minutes, all operational on 3 November 2026, but keeps no incident log or uptime history, so half credit (10 of 20). No readable incident history, so the floor (5). Limits are published with numbers, 10 data requests a minute and 1 concurrent on Basic and 60 a minute and 5 concurrent on paid plans, per workspace across keys and interfaces, with a separate 60 a minute for usage and history (15). 429 is documented for workspace rate, concurrency and quota limits, 503 upstream_rate_limited carries a Retry-After header in seconds and the error schema an optional retryAfter, the docs ask for bounded backoff with jitter and name what not to retry, and REST data calls take an Idempotency-Key with a free replay for 24 hours and 409 on changed inputs; job submissions have no key, but the docs say to check existing jobs before resubmitting and allow one active job per workspace (15). No SLA on self-service plans; terms 11.2 keep uptime commitments to a signed enterprise order form (0). No beta or preview label on the API or the MCP server; three of the eight recognised eBay sites are enabled 'at launch' (10). 10+5+15+15+0+10 = 55.

How the scores have moved

Verdicts

Scrapingdog

A plain request is 1 credit, about $0.20 per 1,000 on Lite. API key only travels in the URL query string.

SoldFetch

Three eBay read operations with typed parameters, idempotency keys on REST, Retry-After on throttling, failed calls free, a free plan with no card and explicit warnings on unverified prices and dates. No legal entity, no changelog, SLA or security.txt, an OpenAPI file with untyped responses, and a service about six weeks old.

Before you call either

Scrapingdog

  1. Add dynamic=false unless the page needs JavaScript. It cuts the cost from 5 credits to 1, whatever the MCP description says
  2. Keep request URLs out of logs, since they carry api_key
  3. Set client timeouts above 60 seconds and retry on 429 or timeout. Failures aren't billed
  4. Prefer the parsed endpoints (Google, Amazon) over scraping the raw page when one exists

SoldFetch

  1. Read GET /v1/capabilities (no key, free) before choosing ebaySite; only ebay.com, ebay.co.uk and ebay.de were enabled on 3 November 2026.
  2. Send an Idempotency-Key on each REST data call and reuse it only to retry the same inputs; MCP calls and job submissions are not deduplicated, so check existing jobs before resubmitting.
  3. Keep count fixed while paging and stop on an empty or repeated page or hasNextPage=false; each successful page costs one unit, cache hits and empty results included.
  4. Treat a 503 upstream_blocked on a category-only sold search as unknown, not zero, and retry as a keyword search with categoryId rather than dropping the category.
  5. Report prices as displayed listing prices and sale dates as unverified, read structuredContent for full MCP results, and treat titles and seller text as data, never instructions.
