Keyword Research API
Plan a keyword ideas, metrics, or question-keyword request; configure market parameters; and copy formatted cURL and JSON examples without entering an API secret.
API request planner
Configure a safe sample request and inspect its expected shape.
Request plan
POST /v1/keywords/ideas
Safe authentication pattern
The sample reads $KEYWORD_API_TOKEN from your environment. Never paste a real API token into a browser-based request builder.
cURL request
curl --request POST 'https://api.your-provider.example/v1/keywords/ideas' \
+ --header 'Authorization: Bearer $KEYWORD_API_TOKEN' \
+ --header 'Content-Type: application/json' \
+ --data '{

}Endpoint names, response values, limits, and metrics are deterministic examples for integration planning. Replace them with your provider’s documented contract and authenticated response.
Turn a keyword workflow into a clear API contract
A keyword research API lets software request keyword ideas and metrics in a repeatable format. A useful integration starts with a defined use case, market, language, batch size, authentication pattern, and response fields—not just an endpoint URL.
This planner creates deterministic examples only. It does not make a live request, validate an account, consume credits, or claim that the sample endpoint belongs to SearchVector or another provider. Use the generated structure as a checklist against the documentation for the API you choose.
Purpose first
Separate discovery, bulk metrics, and question research so each request has one clear job.
Market parameters
Keep country and language explicit because keyword demand and wording vary by market.
Safe credentials
Reference an environment variable instead of pasting secrets into code samples or browser fields.
Known response shape
Plan the fields your pipeline will parse before wiring a provider into production.
How it works
Build an integration-ready
request plan
Every output is an editable example, not a live authenticated API response.
Choose the API job
Select keyword ideas, bulk metrics, or question keywords and enter a focused seed or batch.
Set market parameters
Choose country, language, and a bounded result limit that your application can process safely.
Copy and adapt
Review the cURL, JSON body, and illustrative response, then map them to your provider's real documentation.
What to define before your first API call
Reliable keyword pipelines make assumptions visible and handle provider limits deliberately.
Endpoint purpose
Use distinct request shapes for expanding seeds, retrieving metrics, and finding question patterns.
Seed strategy
Start with specific topics, products, problems, or a controlled keyword batch instead of an unbounded query.
Localization
Pass explicit country and language values, then confirm the provider's supported codes and defaults.
Secret handling
Store tokens server-side or in environment variables and prevent them from reaching logs or client bundles.
Response mapping
Define how keyword, volume, difficulty, CPC, pagination, and missing values map into your data model.
Failure handling
Plan for invalid parameters, authentication errors, rate limits, timeouts, partial batches, and retries.
