What is the Authoritas API?

The Authoritas 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. No official SDK was detected, so most teams hit it directly with HTTP clients.

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 Authoritas 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 Authoritas API actually cost?

Verify on docs

Authoritas 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 Authoritas API

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

SOLO DEV / FOUNDER

Glue Authoritas 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 Authoritas reporting at scale

  • White-label Authoritas data into client-branded dashboards
  • Run scheduled multi-account reports without logging into the Authoritas 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 Authoritas

  • Real-time sync into your warehouse on a cron
  • Custom alerts the dashboard's built-in alerting can't express
  • Backfill + idempotency handling for Authoritas 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 Authoritas API docs: https://www.authoritas.com/keyword-ranking-api

curl -X GET "https://www.authoritas.com/<your-endpoint>" \
  -H "Authorization: Bearer $YOUR_API_KEY" \
  -H "Accept: application/json" | jq .

Template only. Endpoint paths, exact base URL, and auth header format come from authoritas.com/keyword-ranking-api.

Limits and gotchas

  • No OpenAPI spec — you write typed clients by hand or use a third-party generator on the docs HTML.
  • No official SDK detected. Plan on hitting the API directly with your HTTP client of choice.
  • 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

Avoid for agent workflows. Authoritas has documented API access with key auth, but lacks MCP support, OpenAPI specs, SDKs, and structured outputs that agents need to integrate reliably. Without these integrations, you'll be writing custom parsing logic instead of leveraging agentic patterns.
