What is the LinkResearchTools API?

The LinkResearchTools API is a public REST interface to keyword data, backlink profiles, SERP positions, and site-audit results. Auth is handled with an API key in a header. Official SDKs cover node, which keeps boilerplate to a minimum. An OpenAPI spec is published, which means you can auto-generate typed clients from it.

Typical builds: scheduled rank trackers that alert on position drops, competitor monitoring dashboards, and automated site-audit reports piped into Slack or a BI tool.

For agent workflows, the API is the path of least resistance until LinkResearchTools ships an MCP server. ask Claude to summarise this week's ranking shifts, have Cursor draft on-page fixes from a fresh site audit, and let Codex compare your backlink profile to a named competitor.

For the broader picture: full coverage on this tool.

How much does the LinkResearchTools API actually cost?

Verify on docs

LinkResearchTools publishes an API, but per-tier gating wasn't extracted automatically.

  • Most likely scenario: API access is either included in all paid plans, or it's gated to higher tiers and we need to verify on the live docs page.
  • Until verified, treat the question "which plan unlocks the API" as open. Don't budget on the assumption it's free with the cheapest paid plan.

What you can build with the LinkResearchTools API

Three personas, three different shapes of build. Pick the row that matches how you actually ship.

SOLO DEV / FOUNDER

Glue LinkResearchTools into your daily workflow

  • Pull a digest of ranking changes into your morning Slack
  • Trigger a one-off backfill when something looks off
  • Pipe data into your own SQLite for ad-hoc queries
Effort: A weekend, one Node or Python script
AGENCY / CONSULTANT

Sell LinkResearchTools reporting at scale

  • White-label LinkResearchTools data into client-branded dashboards
  • Run scheduled multi-account reports without logging into the LinkResearchTools UI
  • Cross-reference with the rest of the client's stack (CRM, analytics, ad spend)
Effort: 1-2 weeks, hits multi-tenant auth quickly
IN-HOUSE ENGINEER

Production pipelines for LinkResearchTools

  • Real-time sync into your warehouse on a cron
  • Custom alerts the dashboard's built-in alerting can't express
  • Backfill + idempotency handling for LinkResearchTools data older than the dashboard exposes
Effort: Multi-week project, expect rate-limit tuning

Quickstart template

# Starter template — endpoint paths and SDK package names come from
# the LinkResearchTools API docs: https://smart.linkresearchtools.com/docs/03-discover-lrt/3-api-integrations/lrt-api/lrt-api-specification

curl -X GET "https://smart.linkresearchtools.com/<your-endpoint>" \

  -H "Accept: application/json" | jq .

Template only. Endpoint paths, exact base URL, and auth header format come from smart.linkresearchtools.com/docs/03-discover-lrt/3-api-integrations/lrt-api/lrt-api-specification.

Limits and gotchas

  • OpenAPI is published — auto-generated clients work out of the box. Saves writing wrappers by hand.
  • Official SDKs: node. Use them to skip auth boilerplate and get type safety.
  • Rate limits: always read the docs page before scaling — the published limit is usually lower than the practical one and overages can be expensive.
4/10

Agent-readiness verdict

Not recommended for agent workflows. LinkResearchTools has a documented API with OpenAPI spec and Node SDK support, but lacks MCP server availability, webhooks, and structured outputs that enable seamless Claude or Cursor integration. You'd need custom wrapper code to make it talk to modern AI agents.
