cost, credits sell from $50 for 250,000 with no expiry, and a 14-day trial needs no card. Keys carry full account access with no scopes or read-only mode, the key may travel in the URL, and no security page, SLA or llms.txt was found.\n\n## Facts\n\n| Field | Value |\n| --- | --- |\n| Vendor | SE Ranking (SER Acquisition Inc.) (https://seranking.com) |\n| Kind | HTTP API |\n| Category | SEO \u0026 search visibility (https://www.anchorterminal.com/categories/seo) |\n| Transport | HTTP, Streamable HTTP |\n| Endpoint | `https://api.seranking.com` |\n| Auth | OAuth or key · REST calls take an API key as `Authorization: Token \u003ckey\u003e`, or as an `apikey` query parameter. One key covers the Data, Project, Local Marketing and SE Visible APIs, with no scopes. Keys are self-serve in the API dashboard of any plan or trial, with no app review. The MCP server signs in by OAuth 2.1 with dynamic client registration against the SE Ranking account, or takes the key in an `X-Api-Key` header. Sub-accounts have no keys of their own yet. Direct competitors, resale and embedding raw data in a paid product need written consent. |\n| Pricing | Pay per use ($0.0002 / credit) · Data API calls spend credits, from $50 for 250,000 pay-as-you-go credits that don't expire. Each endpoint's credit cost is published and failed requests cost nothing. Subscription plans include 10,000 to 100,000 credits a month, an add-on starts at $540 a year for 3 million credits, and a standalone API plan at $2,148 a year for 12 million. Project API calls use the plan's limits instead of credits. A 14-day trial with 100,000 credits and MCP access needs no card and lets an agent start without a contract.

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.\n\n| Category | Weight | This run | Score (0–100) | Points |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% | 20 | 51 | 10.2 |\n| Performance | 10% | pending | pending | n/a |\n| Schema \u0026 documentation | 13% | 16.2 | 58 | 9.4 |\n| Agent ergonomics | 13% | 16.2 | 58 | 9.4 |\n| Security \u0026 auth | 14% | 17.5 | 21 | 3.7 |\n| Payments \u0026 pricing | 10% | 12.5 | 40 | 5.0 |\n| Task success | 10% | pending | pending | n/a |\n| Maintenance \u0026 community | 7% | 8.8 | 79 | 6.9 |\n| Transparency \u0026 trust (editorial 59, provenance 83) | 7% | 8.8 | 71 | 6.2 |\n| Negative events | up to −15 | up to −15 | none recorded | 0 |\n| **Total** | | | | **50.9 → D** |\n\n### Why each score\n\n- Reliability 51: Graded on the hosted lines for the REST APIs and the MCP server. A status page titled SE Ranking Online Status answers at status.seranking.com, run on Pulsetic. It isn't linked from the pages we read and its components are drawn by script, so we could confirm the page but not its components (12 of 20). Its incident history was unreadable for the same reason (5). Limits are published as 10 requests a second for the Data API, 5 for the Project API and 1 for trial accounts, counted per key over a rolling second (15). The docs describe 429 and recommend exponential backoff with jitter. No Retry-After header and no idempotency key for Project API writes were found, and repeated overruns block the Project API for 10 minutes (10). Section 2.1 of the API terms says there is no service level agreement unless a separate written agreement states one (0). The Data API, Project API and MCP server carry no preview label. The SE Visible API is marked Beta (9). Total 51.\n- 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.\n- Schema \u0026 documentation 58: An OpenAPI 3.0.0 file for the Data API (64 paths, 86 operations) is in the vendor's GitHub organisation. Every response in it is a 200 with no schema, it has no file for the Project, Local Marketing or SE Visible APIs, and the docs pages we read link a Postman collection instead. MCP input schemas weren't read (14 of 25). seranking.com/llms.txt and /api/llms.txt return 404 and no Markdown twins were found (0). Each endpoint page states its purpose, cost and every parameter, and the pricing FAQ says when to use the Data API and when the Project API (14). Parameter tables give type, required status, default and ranges, and the spec carries 56 enums. Filters are bracketed query parameters (11). Every endpoint has a curl request and a JSON response sample and each API has an error table. The tables disagree, with `Insufficient funds` given as 403 on one page and 400 on another (11). Paths are versioned under `/v1`. The What's New page lists API releases by year without dates in its HTML, and the registry dates each MCP version (8). Total 58.\n- Agent ergonomics 58: The MCP page says the server has 180+ tools, and no toolset, read-only subset or tool filter is documented, which is 5 on the MCP line. Data API calls take `cols` and `limit` to size a response, so we scored between the two (10). `limit` on 24 operations and `offset` on 13 in the spec, with `order_field` and range filters on keyword and domain reports. `limit` above 1,000 is capped without an error (17). Errors are JSON with a code, message and description, and the tables list the common causes. Status codes for the same error differ between pages (14). Data API reads are safe to repeat and 4xx and 5xx responses cost no credits. No idempotency key was found for Project API writes and MCP annotations weren't read (10). Few required parameters and stated defaults. The vendor's API page says there are no first-party SDKs (7). Total 58.\n- Security \u0026 auth 21: API keys are created and named in the API dashboard, several to an account, and the MCP server signs in by OAuth 2.1 with dynamic client registration. Keys have no scopes, and the terms mention rotation only where available (22). The key is also accepted as an `apikey` query parameter on every API, and the OpenAPI file documents only that method (minus 10, leaving 12). The MCP docs say restricted or read-only keys aren't available yet and that a key has the same access as the account. No approval step was found for Project API deletes (3). Responses carry third-party anchor text, page titles and AI answers, and no prompt-injection guidance was found (0). The API dashboard shows credit usage and the terms say SE Ranking keeps API logs. No per-call log for the customer is documented (4). No security page, SOC 2 or ISO 27001 statement or bug bounty was found, and /.well-known/security.txt answered 403. The privacy statement says security measures are in place without naming them (2). Total 21.\n- Payments \u0026 pricing 40: No x402, MPP or L402 (0). The docs publish a credit cost for every Data API endpoint and dollar prices for credits, from $50 for 250,000 pay-as-you-go credits to $179 per million on the smallest annual plan (20). The pricing page states a 14-day trial with 100,000 credits, API and MCP access and no card (20). A person signs up in a browser and confirms an email address before a key is issued (0). Total 40.\n- 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.\n- Maintenance \u0026 community 79: The official MCP registry dates version 2.5.1 of `com.seranking/mcp` at 28 September 2026, 10 days before the check (30). Six versions were published in the last 90 days, on 17 July, 18 August and 8, 15, 24 and 28 September (20). A What's New page, a support address for the API, a demo booking form and public GitHub repositories with issues open to all. We found no developer forum (9). The server is in the official registry under the `com.seranking` namespace (15). The OpenAPI repository has a lint workflow and one commit on its main branch, from 8 April 2026, and the skills repository has CI and signed releases to version 2.10.4 (5). Total 79.\n- Transparency \u0026 trust 71: Closed service with API Terms of Service dated 3 March 2026 that cover commercial use, credits and credentials. Sections 1.3 and 2.6 say credentials are specific to each API and section 1.15 ties the Project API to Business or Enterprise plans, while the docs say one key works everywhere on every plan. The skills and OpenAPI repositories are MIT (14 of 30). The privacy statement of 25 June 2026 gives retention periods by purpose and says personal data isn't used to train general AI models. Retention of API logs is left to that statement, no DPA is on the legal page, and the API terms link a privacy URL that differs from the live one (19). Section 13 of the API terms promises up to 30 days' notice of breaking changes where practicable and reserves removal of deprecated functionality at any time (9). A processors page of 25 June 2026 names each processor with purpose and country, Hetzner in Germany and Amazon Web Services in Luxembourg for hosting, and promises two weeks' notice of new ones (17). Total 59.\n\nFix list for a coding agent, everything this grade says the listing lacks, the biggest gain first (21 items): https://www.anchorterminal.com/fixes/se-ranking.md (JSON https://www.anchorterminal.com/fixes/se-ranking.json)\n\n### What we couldn't check\n\n- unchecked: the status page's components and incident history. status.seranking.com is drawn by script and we did not pull its data feed, so reliability may be understated by up to 33 points or overstated by 12\n- unchecked: the MCP server's tool definitions, input schemas, annotations and exact tool count, which need a signed-in account.

The docs say one key and every plan. We recorded the docs and noted the terms\n- The docs give the smallest standalone plan as 12 million credits a year in one place and 24 million in another, and the pricing page labels it 1M credits a year\n- The OpenAPI repository is in the vendor's GitHub organisation and is not linked from the docs pages we read. Its SERP paths (`/v1/serp/classic/*`) have no page in the docs sidebar\n- No security page or certification statement was found in the page sitemap, the legal index or the footer. If one exists elsewhere the security score is understated\n- The last few requests ran shortly after midnight on 9 October 2026.

Capped at the fees paid in the 12 months before the claim.\n- Says how changes to the terms are announced. Changes are posted, with no other notice named.\n- Also in the text (2026-10-08). Using API data to train public machine learning or language models is listed among the uses that need SE Ranking's prior written consent. \"(3) Use of API data to train public machine learning or language models.\"\n- Also in the text (2026-10-08). The customer may not share API credentials with a third party or let a third party make direct API calls with them unless SE Ranking permits it in writing. \"Customer shall not share API Credentials with any third party, including Customer’s clients, nor allow any third party to make direct API calls using Customer’s API Credentials, unless expressly permitted in writing by Provider.\"\n- Also in the text (2026-10-08).

A backlink summary is 100 credits a target |\n| Standalone API plan, 12 million credits a year | $179 | per month (plan) | billed annually at $2,148, Data API only |\n| API add-on, 3 million credits a year | $45 | per month (plan) | billed annually at $540, on top of a subscription |\n\nAcross all listings: https://www.anchorterminal.com/prices/index.md\n\n## Strengths\n\n- Credit cost is published per endpoint, failed requests aren't charged, and pay-as-you-go packs start at $50 for 250,000 credits that don't expire\n- A 14-day trial with 100,000 credits covers the API and the MCP server, with no card, per the pricing page\n- Hosted MCP server at `https://api.seranking.com/mcp`, listed in the official MCP registry as `com.seranking/mcp` with 15 versions since 22 May 2026\n- Rate limits are stated as 10 requests a second for the Data API and 5 for the Project API, with backoff guidance for 429\n- `limit`, `offset`, `cols` and bracketed `filter` parameters size Data API responses, and an OpenAPI 3.0 file covers its 86 operations\n\n## Weaknesses\n\n- No scoped or read-only keys. The MCP docs say a key has the same access as the account, including Project API deletes\n- The API key is accepted as an `apikey` query parameter, and the OpenAPI file and its README describe only that method\n- No security page, certification statement, bug bounty or readable security.txt was found, and the API terms say there is no SLA without a separate agreement\n- The MCP server advertises 180+ tools with no documented way to load a subset\n- The API terms let SE Ranking remove deprecated functionality at any time, with up to 30 days' notice only where practicable\n\n## Before you call it (notes for agents)\n\n1. Send the key as `Authorization: Token \u003ckey\u003e`, not `Bearer` and not `?apikey=`, so it stays out of URLs and logs\n2. Call `GET /v1/account/subscription` (0 credits) and read `units_left` before a large pull. A short balance returns `Insufficient funds`\n3. Set `limit` and `cols` on per-record endpoints. Backlink summaries cost 100 credits a target and keyword rows 10 credits each\n4. Stay under 10 requests a second on the Data API and 5 on the Project API per key. Repeated overruns block the Project API for 10 minutes\n5. Ask the owner before any Project API or `PROJECT_*` create, update or delete call. The key has no read-only mode and nothing confirms a delete\n\n## Connect\n\nFirst request:\n\n```bash\ncurl -X GET 'https://api.seranking.com/v1/account/subscription' -H 'Authorization: Token YOUR_API_KEY'\n```\n\nClaude Code:\n\n```bash\nclaude mcp add --transport http se-ranking https://api.seranking.com/mcp\n```\n\nMCP client configuration:\n\n```json\n{\n \"mcpServers\": {\n \"se-ranking\": {\n \"url\": \"https://api.seranking.com/mcp\"\n }\n }\n}\n```\n\nThrough letme (picks today, calling later): https://letme.dev/se-ranking. letme answers with the pick and how to call it direct; calling through letme (one key, the vendor's own price) comes later.
