# Majestic API > Majestic crawls the web and sells backlink data. Its HTTP API returns backlinks, referring domains, anchor text, Trust Flow and Citation Flow scores and keyword counts from a Fresh and a Historic index, as XML or JSON. - Canonical: https://www.anchorterminal.com/tools/majestic - Markdown: https://www.anchorterminal.com/tools/majestic.md (~8,250 tokens) - Slim: https://www.anchorterminal.com/tools/majestic.min.md (~1,980 tokens, same facts, less prose, for token-sensitive contexts) - JSON: https://www.anchorterminal.com/tools/majestic.json (this page as data, same URL with Accept: application/json) - Site index for agents: https://www.anchorterminal.com/llms.txt (full text: https://www.anchorterminal.com/llms-full.txt) - API: https://www.anchorterminal.com/api/v1/index.json - Updated: 2026-10-10 ## Overview **Grade F · 33.4/100 · rank #937 of 950 · #10 in SEO & search visibility · not agent-ready · confidence medium** ## Assessment Each command's cost in units is published and a sandbox endpoint returns sample data without spending allowance. API access starts at $399.99 a month with no trial, and no OpenAPI file, status page, numeric rate limit, SLA or API changelog was found. The supply terms require permission before querying with automated tools. ## Facts | Field | Value | | --- | --- | | Vendor | Majestic (Majestic-12 Limited) (https://majestic.com) | | Kind | HTTP API | | Category | SEO & search visibility (https://www.anchorterminal.com/categories/seo) | | Transport | HTTP | | Endpoint | `https://api.majestic.com` | | Auth | API key · An API key, sent as the `app_api_key` parameter by POST or GET, or as a cookie on GET requests. Keys are created under My Account, API Keys, and only on an API plan or the legacy Platinum plan. An account can hold several keys, each of which can be disabled and limited to IP addresses or CIDR ranges. Keys have no scopes. Third-party apps use OpenApps instead, where each user approves the app once and the app sends its private key with that user's access token. Resale of the data needs a reseller agreement through sales. | | Pricing | Paid ($399.99 / mo) · API access needs the API plan, $399.99 a month or $3,999.90 a year for 100 million analysis units, 20 million retrieval units and 500,000 index item units a month. The 300 million tier is $799.99 a month and the 1,000 million tier $1,599.99. Lite ($49.99) and Pro ($99.99) have no API access. No trial or free API key was found, and the 7-day refund covers Lite and Pro only. A sandbox endpoint costs no units but needs a key from a paid API plan. Prices exclude VAT (checked 2026-10-09). | | x402 | No · No x402, MPP or L402 in the developer docs, either llms.txt or the pricing page (checked 2026-10-09). | | Licence | Proprietary service under Majestic's Terms and Conditions.

Confidence: medium. Performance and Task success pending (no score, not in the total); the total is Σ(score × weight) ÷ 80 over the 7 assessed categories. "This run" is each category's share of the 100 points. | Category | Weight | This run | Score (0–100) | Points | | --- | --- | --- | --- | --- | | Reliability | 16% | 20 | 17 | 3.4 | | Performance | 10% | pending | pending | n/a | | Schema & documentation | 13% | 16.2 | 44 | 7.2 | | Agent ergonomics | 13% | 16.2 | 54 | 8.8 | | Security & auth | 14% | 17.5 | 32 | 5.6 | | Payments & pricing | 10% | 12.5 | 15 | 1.9 | | Task success | 10% | pending | pending | n/a | | Maintenance & community | 7% | 8.8 | 22 | 1.9 | | Transparency & trust (editorial 43, provenance 63) | 7% | 8.8 | 53 | 4.6 | | Negative events | up to −15 | up to −15 | none recorded | 0 | | **Total** | | | | **33.4 → F** | ### Why each score - Reliability 17: Graded on the hosted lines. No status page was found. None is linked from the site footer, the developer docs or either llms.txt (0 of 20), so there is no incident record to read (0 of 30). The docs publish monthly unit allowances, batch sizes (100 items, 1,000 keywords, 50,000 rows) and one concurrency limit, 5 requests at once when sorting or filtering. No requests-per-second figure was found, and clause 13 of the supply terms lets Majestic throttle access at its discretion (6 of 15). No 429 or overload guidance and no Retry-After were found. Nearly every command is a read, and `SkipIfAnalysisCostGreaterThan` stops an oversized download (2 of 15). No SLA was found, and the terms disclaim liability for unavailability (0). The API carries no preview label, with one command, GetRelatedSites, marked Beta (9 of 10). Total 17. - Performance: Pending. Latency is measured per call by our probes, which haven't run yet, so this run doesn't score it. Its weight is shared across the assessed categories until the first probe window closes. - Schema & documentation 44: No OpenAPI file or other machine-readable contract was found (0 of 25). Both majestic.com and developer-support.majestic.com serve an llms.txt, and the developer one links an llms-full.txt of its 39 pages (10). Each command page states its purpose, its status, its unit cost and whether it may be queued, and the overview says which command suits large domains (14 of 20). Parameter tables give defaults, maxima and allowed values, and `SortBy1` and `FilteringDepth` list their options. `Filters` is a string expression language of its own (9 of 15). Every command page read has XML and JSON samples, dated 2017. The errors page lists two universal codes and four OpenApps codes, and other codes appear only in passing (9 of 15). The API has no version in its path, no changelog was found, and the deprecated commands table gives replacements without dates (2 of 15). Total 44. - Agent ergonomics 54: `Count`, `From`, `MaxSourceURLsPerRefDomain` and `MaxSameSourceURLs` size a GetBackLinkData response. There is no field selection, and a GetIndexItemInfo row in the sample carries more than 70 columns (12 of 25). `Count` up to 50,000 with `From` for paging, two sort keys and up to 25 filters a query, at an extra 5,000 to 15,000 analysis units (17 of 20). Every response has `Code`, `ErrorMessage` and `FullError`, though few codes are documented (9 of 20). Commands are reads and can be repeated, but each call spends units and the docs don't say whether a failed call is charged. A sandbox host costs nothing (8 of 20). Most commands need only `cmd` and an item, with stated defaults. Connectors exist in eight languages as source on GitHub, last updated between 2016 and 2021 and not on a package registry (8 of 15). Total 54. - Security & auth 32: An account can hold several API keys, each of which can be disabled and limited to IP addresses or CIDR ranges. OpenApps gives each user a revocable access token paired with the app's private key. Keys have no scopes (22 of 30). The docs show the key as an `app_api_key` URL parameter on GET, advise POST or a cookie instead, and say plain HTTP is still accepted (minus 10, leaving 12). The API is close to read-only, with AddToBucket, SubmitURLsToCrawl and DeleteDownloads the writes found, and the IP allow-list narrows a key. No read-only key or approval step exists (8 of 20). Responses carry third-party anchor text and page titles, and no prompt-injection guidance was found (0 of 15). An IP activity page shows usage by key and address, and GetSubscriptionInfo returns allowance used (9 of 15). The developer security page gives key-handling advice. No security.txt (404), certification, bug bounty or disclosure policy was found (3 of 20). Total 32. - Payments & pricing 15: No x402, MPP or L402 (0 of 40). Plan prices are public in dollars, pounds and euros, each command's unit cost is published and the plan states its monthly units, so a cost per call can be worked out. There is no pay-as-you-go price (15 of 20). API access starts at the $399.99 API plan. No trial or free key was found, the sandbox needs a key from that plan, and the 7-day refund covers Lite and Pro only (0 of 20). A person buys a plan in a browser and creates a key in the account (0 of 20). Total 15. - Task success: Pending. Task success needs the category task suites run through each tool, which haven't run yet, so this run doesn't score it. Its weight is shared across the assessed categories until then. A data provider's data-quality score is published on its listing now and becomes half of this category when it's scored. - Maintenance & community 22: No API changelog or release list was found, and the site updates page is behind the account login. The newest dated product change found is a blog post of 30 July 2026 on a Site Explorer chart, 71 days before the check. The newest dated change to the developer docs is the llms.txt of 26 January 2026, 256 days before. We scored between the two (10 of 30). No three dated API or product releases in the last 90 days (0 of 20). Support is a contact form and an email address, with no public developer forum or issue tracker in use (5 of 15 on the closed-service line). The connectors on GitHub were last updated between March 2016 and September 2021 (5 of 15). They have no CI and no package registry entry (2 of 10). The Fresh Index itself was updated 40 minutes before our read, per the site footer. Total 22. - Transparency & trust 53: Closed service with public Terms and Conditions released on 13 April 2026. They are subscription terms with no API section, they still name Silver, Gold and Platinum levels, and they limit use to research. The connectors carry a BSD-style licence (13 of 30). The privacy policy (updated April 2026) names the controller, gives a seven-year retention period for basic customer records and names its outside processors. It still cites the EU-US Privacy Shield as a transfer mechanism, and no DPA or retention period for API request logs was found. A separate GDPR statement covers personal data met in crawling (16 of 30). The command overview marks four commands deprecated with their replacements and no dates, and the terms let Majestic withdraw or amend the service without notice (6 of 20). The privacy policy names Cybersource, PayPal, Zendesk, Infusionsoft, Zapier, Dropbox and Acuity, with no hosting provider or data location stated (8 of 20). Total 43. Fix list for a coding agent, everything this grade says the listing lacks, the biggest gain first (24 items): https://www.anchorterminal.com/fixes/majestic.md (JSON https://www.anchorterminal.com/fixes/majestic.json) ### What we couldn't check - Clause 14.1(f) of the Terms and Conditions of Supply says a subscriber shall not query Majestic's database or servers using any automated tools without prior permission. Recorded as a fact with no deduction. It matters before any probe is run, and whether an API plan counts as that permission is not stated - unchecked: whether a status page exists. None is linked from the pages read, and we did not try guessed addresses - unchecked: the site updates page at majestic.com/account/site-updates, which redirects to the login. Maintenance may be understated if it lists dated API changes - unchecked: retrieval and index item allowances of the 300 million and 1,000 million tiers, which the page sets by script - unchecked: the remaining command pages, the authentication page and llms-full.txt. Twelve of the 39 docs pages were read - unchecked: the API's live behaviour. No request was sent to api.majestic.com or developer.majestic.com, so error bodies, HTTP status codes and rate limiting are as documented only - unchecked: whether failed or empty calls spend analysis units - The API reference names `http://enterprise.majestic.com/api_command` in its Response Types section and `https://api.majestic.com/api_command` elsewhere. We recorded api.majestic.com - The supply terms name Free, Silver, Gold and Platinum levels. The pricing page sells Lite, Pro and API, and the docs call Platinum a legacy plan - The pricing page showed our request pounds by default. Dollar prices came from the same page after its own currency selector, and they match the llms.txt - `lastRelease` is null because no dated API release was found - The lead was right about the vendor, the docs address and the commands. The API host is api.majestic.com, not the docs host ### Sources - developer docs home: (seen 2026-10-09) - API reference guide: (seen 2026-10-09) - command overview and unit costs: (seen 2026-10-09) - GetBackLinkData: (seen 2026-10-09) - GetIndexItemInfo: (seen 2026-10-09) - GetSubscriptionInfo: (seen 2026-10-09) - GetKeywordInfo: (seen 2026-10-09) - DownloadBackLinks: (seen 2026-10-09) - API security page: (seen 2026-10-09) - common errors: (seen 2026-10-09) - OpenApps guide: (seen 2026-10-09) - connectors: (seen 2026-10-09) - developer llms.txt: (seen 2026-10-09) - majestic.com llms.txt: (seen 2026-10-09) - plans and pricing (pounds by default, dollars through the page's currency selector): (seen 2026-10-09) - Terms and Conditions: (seen 2026-10-09) - privacy policy: (seen 2026-10-09) - GDPR compliance statement: (seen 2026-10-09) - about page: (seen 2026-10-09) - FAQ: (seen 2026-10-09) - security.txt (404): (seen 2026-10-09) - blog home and its Development and Updates categories: (seen 2026-10-09) - GitHub organisation page: (seen 2026-10-09) - Python 3 connector (shallow clone): (seen 2026-10-09) - robots.txt: (seen 2026-10-09) - domain registration: (seen 2026-10-09) ## Who's behind it (provenance 63/100, checked 2026-10-09) | Check | Finding | Points | | --- | --- | --- | | Legal entity named | Majestic-12 Limited | 20/20 | | Domain age | majestic.com, registered 2001-05-03 (25 years) | 15/15 | | Endpoint on the vendor's domain | api.majestic.com | 15/15 | | Terms of service | read, states 4 of the 7 things a reader expects, and has 2 clauses that cost points | 3.4/10 | | Privacy policy | read, states 7 of the 8 things a reader expects | 9.3/10 | | Status page | not found | 0/10 | | Changelog | not found | 0/10 | | security.txt | not found | 0/10 | The Terms and Conditions (released 13 April 2026) are one page holding the Terms of Website Use, the Acceptable Use Policy and the Terms and Conditions of Supply.

The supply terms still name Free, Silver, Gold and Platinum subscription levels, which are not the plans on the pricing page. The privacy policy applies from 3 May 2019 and says it was last updated in April 2026. It names Majestic-12 Limited as controller. The API answers at api.majestic.com and the sandbox at developer.majestic.com. majestic.com/.well-known/security.txt returned 404.

Live uptime, where we poll the endpoint, is under Live and doesn't change the score. ## Prices | Item | Price | Unit | Note | | --- | --- | --- | --- | | API plan, 100 million analysis units a month | $399.99 | per month (plan) | with 20 million retrieval units and 500,000 index item units. $3,999.90 billed annually. Excludes VAT | | API plan, 300 million analysis units a month | $799.99 | per month (plan) | $7,999.90 billed annually. Excludes VAT | | API plan, 1,000 million analysis units a month | $1599.99 | per month (plan) | $15,999.90 billed annually. Excludes VAT | | GetBackLinkData, per call | $0.02 | per call | our arithmetic. 5,000 of the 100 million analysis units in the $399.99 plan, before retrieval units for rows returned | Across all listings: https://www.anchorterminal.com/prices/index.md ## Strengths - Every command page states its cost in analysis units, and `GetSubscriptionInfo` returns the remaining allowances at no cost - A sandbox endpoint at `developer.majestic.com` answers the same commands from a reduced Historic data set without spending allowance - Several API keys per account, each of which can be disabled and limited to IPv4 addresses or CIDR ranges, with an IP activity page per key - `GetIndexItemInfo` takes up to 100 items a call and `GetKeywordInfo` up to 1,000 keywords, and `GetBackLinkData` has `Count`, `From`, sorting and a `Filters` expression - Both docs hosts publish an `llms.txt`, and the developer one (dated 26 January 2026) links an `llms-full.txt` of all 39 pages ## Weaknesses - Clause 14.1(f) of the supply terms forbids querying Majestic's database or servers with automated tools without prior permission. This matters before any probe is run - API access needs the API plan, from $399.99 a month for 100 million analysis units. No trial or free key was found, and the 7-day refund covers Lite and Pro only - No OpenAPI file, no API version and no API changelog were found. Sample responses in the docs carry 2017 index dates - No status page, SLA or numeric rate limit was found. The terms allow throttling at Majestic's discretion and disclaim liability for unavailability - The docs show the key as an `app_api_key` URL parameter and say plain HTTP is still accepted for legacy clients - The connectors on GitHub were last updated between March 2016 and September 2021 and are not on a package registry ## Before you call it (notes for agents) 1. Send requests by HTTPS POST with `app_api_key` in the body. The docs show GET URLs for demonstration only and plain HTTP still works 2. Always set `datasource=fresh` or `datasource=historic`. Without it the Historic Index is used when the plan includes it 3. Call `GetSubscriptionInfo` (no cost) before a large pull. `GetBackLinkData` spends 5,000 analysis units a call plus one retrieval unit a row 4. Read columns by header name, not position. The docs say column order can change between requests and Majestic may vary rows and columns at any time 5. Develop against `https://developer.majestic.com/api/json`, which costs no units, then switch the host to `api.majestic.com` 6. Ask the owner to confirm Majestic's permission for automated querying first. Clause 14.1(f) of the terms requires it ## Connect First request: ```bash curl -X POST 'https://developer.majestic.com/api/json' -d 'app_api_key=API_KEY' -d 'cmd=GetIndexItemInfo' -d 'items=1' -d 'item0=majestic.com' -d 'datasource=fresh' ``` Through letme (picks today, calling later): https://letme.dev/majestic. letme answers with the pick and how to call it direct; calling through letme (one key, the vendor's own price) comes later.

The badge or a plain link to this page verifies the listing, from a page on majestic.com or one of its subdomains, or the README of github.com/majestic/Python3-API-Connector. It shows the listing is the vendor's and that the vendor knows it's here, and it never changes a grade, rank or review. The vendor sends the page's address to `POST https://www.anchorterminal.com/api/v1/verify` as `{"slug": "majestic", "url": "…"}`, or calls the `verify_listing` tool at https://www.anchorterminal.com/mcp. We fetch the page once, then again every week; two failed checks in a row and the verification lapses, and a later pass restores it.
