What is data-for-seo?

A set of APIs for search-engine results, keyword measurements, backlinks, app-store information, website audits, and domain data. SEO means improving how easily a website appears in search engines.

Use it for keyword research, rank tracking, backlink checks, competitor analysis, technical website audits, and SEO reporting.

It avoids building separate connections for common search and website-analysis data. It helps turn search visibility and competitor information into structured results.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00151	$0.07785
Opus 5	$0.00076	$0.03893
Sonnet 5	$0.00030	$0.01557
Haiku 4.5	$0.00015	$0.00779

Measured 5d ago against content hash 3fb99e02f97e, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-09, from the pricing page.

Security

Grade A, and why

data-for-seo scanned grade A with 0 findings 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 5d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 432 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Data For SEO through One

DataForSEO provides a comprehensive suite of RESTful APIs and data services that deliver search-engine results (SERP), keyword metrics, backlinks, app store info, site technical audits, and domain analytics — giving marketers, developers and agencies access to structured SEO, PPC, and web-market data for rank tracking, competitor analysis, keyword research, and more.

One exposes Data For SEO through four MCP tools. The table below carries real action ids from One's knowledge base, so for a common operation you can skip search and go straight to reading the action's parameters.

How to run an action

Find the action in the table below, or call search_one_platform_actions with platform data-for-seo if it is not listed.
Call get_one_action_knowledge with the action id. Do this every time, including for actions in this table. The table gives you the id, not the parameters.
Call execute_one_action with parameters copied from that knowledge.

Never guess a parameter name, a body field, or an enum value. The knowledge has the real schema, and a guessed field is either a 400 or a silent write of the wrong thing.

Before you start

Call list_one_integrations once and confirm Data For SEO is connected. If it is missing, the user has not connected it: say so and point them at https://app.withone.ai rather than reaching for raw HTTP.

Each connection carries an access field. If it reports {"policy": "methods", "methods": ["GET"]} the agent is read-only here, so plan a read-only answer instead of attempting a write that will be refused.

Before a write

Creates, updates, deletes and sends land on a real Data For SEO account and cannot be recalled. State the action and the specific target in one line before the first write in a task, and let the user stop you. Reads need no confirmation.

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.
