seo-api

seo-api is a skill for Claude Code from seranking/seo-skills. It costs 218 tokens per session (4,011 once invoked), scanned A, original, MIT.

An integration guide for the SE Ranking API, a service that provides SEO data such as keywords, backlinks, search rankings, website audits, and competitor information. It also covers managing SE Ranking projects through the API.

In plain words
What is it for?
Use it to build SEO data integrations in cURL, Python, TypeScript, or MCP clients. It also helps create projects, add keywords, configure audits, manage backlinks, and set up AI prompts.
Why use it?
It removes the need to work out API requests, authentication, tool choices, costs, and limits from scratch. It can provide ready-to-use code or connect to live project data.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

seo-api scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

How it starts

The opening of the file, as written. The whole thing — 191 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Live with the SE Ranking MCP at https://api.seranking.com/mcp. Tool schemas are introspected live; this skill never relies on a frozen snapshot of the API surface.

SE Ranking API Integration Architect

Help developers ship real integrations against the SE Ranking SEO Data API and Project API. The deliverable is either a code recipe (ready-to-paste cURL / Python / TypeScript / MCP-tool-call sequence) or live wiring of Project API state (create projects, add keywords, configure audits, set up AIRT prompts), or both. The skill knows the entire 195-tool surface, the credit and rate-limit cost of every call, and the canonical setup story for every major MCP client.

Prerequisites

  • SE Ranking MCP connected at https://api.seranking.com/mcp. Single API key authenticates both DATA_* and PROJECT_* tools through the unified gateway. If /mcp doesn't show se-ranking, the skill emits the install command and stops — see references/auth-and-keys.md.
  • (Optional) WebFetch for fetching deep guides at seranking.com/api/data/* and seranking.com/api/project/* when the request needs prose beyond JSON Schema.
  • User provides: an integration goal in plain language (e.g., "build a rank tracker for client X", "pull all backlinks for these 50 domains into BigQuery weekly", "configure an audit + AIRT prompts for a new project"). The skill interviews only when the goal is ambiguous.

Process

  1. Preflight.
    • Confirm the SE Ranking MCP is reachable. If not, emit:
      claude mcp add --transport http se-ranking https://api.seranking.com/mcp
      
      and stop. See references/auth-and-keys.md for OAuth vs. X-Api-Key header tradeoffs and headless / CI patterns.
    • Call DATA_getSubscription (0 credits). Record units_left, plan status, expiration — units_left is the figure to forecast against, and it gets printed in the cost forecast in step 5. Optionally also call DATA_getCreditBalance for its { limit, used } view — but the two are not aliases: they report different remaining-credit numbers that do not reconcile (an ~8.6M gap is normal), so treat getSubscription.units_left as the source of truth.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
