LinkedIn KeyAPI Skill

Turn natural-language LinkedIn requests into documentation-guided KeyAPI REST workflows. Start from the user's business goal, map it to the closest scenario, verify the current endpoint contract in the latest KeyAPI docs, then execute the request with a helper script when available or with direct REST when it is not.

Execution Contract

Use KeyAPI REST API execution for live data lookup, ranking, analysis, search, comparison, and reporting.
Treat https://docs.keyapi.ai/llms.txt and linked endpoint pages as the source of truth for method, /v1/... path, parameters, enums, pagination, request body, and response shape.
Do not use platform web pages or manual browsing as a substitute for API data.
Keep credentials local. Never print or restate KEYAPI_TOKEN.
If official docs conflict with this skill, follow the official docs.

Hard Rule

For LinkedIn data lookup, ranking, analysis, search, comparison, or reporting, use KeyAPI API execution and official KeyAPI docs. Do not use platform web pages as a substitute for API results.

Workflow

Apply references/global-rules.md as the base execution contract.
Check auth with node scripts/configure-keyapi-auth.mjs --status when script execution is available and setup state is unknown; treat authStatus: "available" as ready and authStatus: "unavailable" as missing credentials.
If authStatus is unavailable, stop live execution, load references/setup-and-auth.md, and tell the user the exact setup command: node scripts/configure-keyapi-auth.mjs. Do not only say "set KEYAPI_TOKEN".
Identify the user's goal, entity, scope, metric, pagination depth, and desired output.
Use references/scenarios.md to map the request to a LinkedIn scenario.
Use references/routing-policy.md to choose search/list, detail, resolver, ranking/trend, related-entity, or composed workflow patterns.
Apply references/linkedin-rules.md for LinkedIn-specific identifiers, pagination, and reporting rules.
Load the scenario reference named in references/scenarios.md when the request maps to a curated scenario.
Resolve current docs with node scripts/search-keyapi-docs.mjs --query "<semantic entity action>" --resolve when the helper script is available; otherwise open https://docs.keyapi.ai/llms.txt and the selected endpoint page directly. Build the query from the inferred scenario/API concept, not by copying vague or translated user wording literally.
Use the resolver output or opened docs page to extract the current OpenAPI method, /v1/... path, required query/body parameters, examples, and response contract before any live API call. Never infer API paths from docs URLs, scenario names, endpoint titles, remembered routes, or a previous 404.
Ask only for missing high-value inputs that cannot be safely defaulted.
Prefer node scripts/keyapi-api.mjs for live REST calls when script execution is available. Use the host's HTTP client only when scripts are unavailable or the helper cannot express the documented request.
Check HTTP status and KeyAPI response envelope. code = 0 means success; non-zero code is an API-level failure.
Return the result in user-facing analytical language, separating observed API facts from inference.

Interaction Rules

Do not start by listing raw endpoints or dumping all parameters. First identify the user's business goal, choose the closest scenario, collect only missing high-value inputs, resolve the current docs, then execute.
Prefer scenario names and user-facing workflows over endpoint names for non-technical users. Use raw endpoint names only after the route is chosen or when the user asks for integration details.
Treat endpoint selection as semantic routing first: infer the platform data surface and action from the user's goal, then use docs search to verify the current endpoint.
If multiple endpoints could solve the task, choose the one with the least user input burden and strongest documented filtering.
If the user's request is vague, offer 2 to 4 concrete scenario options instead of asking an open-ended question.
If a request needs a broad report or many adjacent calls, confirm the sections and maximum scope before execution.
If credentials are missing, pause live execution and route to setup; do not fall back to platform websites or unauthenticated browsing for API data.

Scenario Selection

Read references/scenarios.md to choose the best scenario card. If no exact scenario fits, use the nearest scenario with explicit assumptions or fall back to advanced mode that exposes filters gradually. Treat the official docs index as the endpoint source of truth, not the scenario card.

Input Model

Compress parameter-heavy APIs into these decision fields:

Goal: search, detail, enrichment, ranking, comparison, monitoring, or report
Entity: the LinkedIn object being searched, analyzed, compared, ranked, or monitored
Scope: person, company, job, post, keyword, location, role, seniority, company size, and hiring context
Metric or sort: relevance, recency, company size, employee count, hiring activity, role fit, post engagement
Pagination depth: one page, top N, until enough evidence, or all available within the user's approved scope
Output format: concise answer, table, raw JSON, or structured report

Scenario Families

Professional profile due diligence
Company profile and employee discovery
Company posts and hiring intelligence
Job list, job count, and job detail analysis
People search and professional network research

KeyAPI-Specific Usage

Prefer API-side filters from the current docs over client-side filtering.
If multiple endpoints could solve the task, choose the one with the least user input burden and strongest documented filtering.
For broad reports, confirm the requested sections before launching a multi-endpoint workflow.
For LinkedIn reporting, separate people, companies, jobs, posts, contact info, work history, education, and skills signals.
If the user asks about integration details, answer with method, path, auth, required params, and a minimal request example from the current docs.

Onboarding Rule

When the user has not set up credentials yet, proactively provide the setup script command. Do not answer only with "configure KEYAPI_TOKEN".

When authStatus is unavailable:

explain that KeyAPI uses Bearer token authentication with KEYAPI_TOKEN
point them to the KeyAPI dashboard and auth docs
require local setup with node scripts/configure-keyapi-auth.mjs when script execution is available
also mention node scripts/configure-keyapi-auth.mjs --status for checking whether authentication is available
explain that setup writes credentials into shell environment variables
explain that --status reports available or unavailable; continue live requests when it reports available
continue live requests only after setup is complete

Script Contract

This skill includes helper scripts under scripts/ for reliable local execution:

scripts/configure-keyapi-auth.mjs
scripts/search-keyapi-docs.mjs
scripts/keyapi-api.mjs

Run script commands from this skill directory. If the host agent uses a different current working directory, resolve scripts/... relative to this SKILL.md. For large JSON bodies, especially base64 image payloads, prefer --body-file or --image-file instead of inline --body. keyapi-api.mjs always sends live API requests; repeating identical requests calls the API again. The helper does not create local response files unless --output-file is supplied. Large responses may return a stdout preview; when complete fields are needed for extraction, sorting, aggregation, or validation, use --output-file to save the full helper result and read the API payload from data.data. For agent-internal analysis, write to a temporary path such as the OS temp directory or a workspace .tmp-keyapi-*.json file; do not present that temporary file as a user deliverable, and clean it up when practical or briefly mention it in the final answer. When the user asks to save results, export JSON, or provide a file, treat --output-file as an intentional user-facing output file. Use --stdout full only when the user explicitly needs raw JSON in stdout. For query strings, prefer repeated --query-param key=value or --param key=value; use --query-file query.json or --query only when structured array/object query values are needed. Query sources merge in this order: --query, --query-file, then repeated query params, with later values overriding earlier ones; empty query-param values are not sent.

Prefer them in this order when script execution is available:

auth status
docs resolution before live REST calls
live REST call

If script execution is unavailable in the host agent, or if the helper cannot express the documented request, do not fail the task. Use the same documented REST method, path, headers, query, and body with the host's available HTTP client.

Script Examples

Resolve current docs for this platform:

node scripts/search-keyapi-docs.mjs --query "<entity action>" --resolve

Execute a documented GET endpoint:

node scripts/keyapi-api.mjs --path /v1/linkedin/... --query-param example=value

Execute query parameters from a JSON file:

node scripts/keyapi-api.mjs --path /v1/linkedin/... --query-file query.json

Preview a large response without saving:

node scripts/keyapi-api.mjs --path /v1/linkedin/... --query-param example=value --stdout preview

Write a complete response to a temporary file for internal analysis:

node scripts/keyapi-api.mjs --path /v1/linkedin/... --query-param example=value --output-file .tmp-keyapi-linkedin-response.json

Save or export a complete response for the user:

node scripts/keyapi-api.mjs --path /v1/linkedin/... --query-param example=value --output-file response.json

Execute a documented POST endpoint:

node scripts/keyapi-api.mjs --path /v1/linkedin/... --method POST --body '{"example":"value"}'

Execute a documented POST endpoint with a large JSON body:

node scripts/keyapi-api.mjs --path /v1/linkedin/... --method POST --body-file request.json

Execute an image JSON endpoint from a local file:

node scripts/keyapi-api.mjs --path /v1/linkedin/... --method POST --query-param example=value --image-file ./image.jpg --image-field image_base64
