What Is the Onxeera API?
The Onxeera API is a REST API that provides programmatic access to Onxeera’s AI citation tracking data — the same citation rate, platform breakdown, competitive comparison, and gap analysis data available in the Onxeera dashboard, delivered as structured JSON responses that integrate with any development environment. The API enables developers and technical marketing teams to build AI citation monitoring directly into their existing systems — marketing dashboards, agency reporting platforms, CRM systems, business intelligence tools, and custom analytics workflows — without relying on manual CSV exports or dashboard screenshots for data transfer. For developers at brands that are actively building GEO programs, the API is the integration layer that makes AI citation data a first-class metric in their marketing data infrastructure rather than a manually-tracked side project.
Key API Endpoints
Citation Rate Endpoint
The /v1/citation-rate endpoint returns the current citation rate for a brand across all four AI platforms — overall citation rate percentage, platform-by-platform breakdown (ChatGPT, Gemini, Perplexity, Google AI Overviews), and citation rate by query category. Pass your brand name and query set as request parameters and receive a structured JSON response with citation rate data for the current measurement period. The endpoint supports both on-demand citation rate requests (triggering a fresh citation test) and historical data requests (returning stored citation rate data from previous measurement cycles) — enabling both real-time citation checks and trend analysis in a single integration.
Competitive Analysis Endpoint
The /v1/competitor-analysis endpoint returns competitive citation rate data for a brand and up to 3 competitors — the same data produced by the Onxeera Competitor Analysis Tool, delivered as a JSON response. Pass your brand name, competitor brand names, and query set and receive a structured competitive citation map including citation rates for each brand by platform and by query category, citation gap identification (queries where competitors are cited and your brand is not), and root cause diagnosis for each identified gap. The competitive analysis endpoint is the highest-value API endpoint for GEO agencies building custom client reporting systems — it automates the competitive citation data collection that previously required manual testing across four platforms.
Citation History Endpoint
The /v1/citation-history endpoint returns historical citation rate data across all stored measurement points for a brand — overall citation rate by month, platform citation rates by month, and competitive citation rates by month where competitive tracking is configured. The historical endpoint is the primary data source for trend analysis — pulling citation rate time series data into BI tools, custom dashboards, or data visualization systems that display GEO program performance over time alongside other marketing channel data. The response includes timestamps for each measurement point, implementation event annotations where manually tagged in the Onxeera dashboard, and competitive citation rates at each historical point where competitive tracking was active.
Gap Analysis Endpoint
The /v1/gap-analysis endpoint returns the current citation gap list for a brand — the specific queries where the brand is not being cited on specific platforms, with root cause diagnosis and gap-closing recommendations for each gap. The gap analysis endpoint is the primary data source for automated GEO action planning systems — pulling gap data into project management tools, content planning systems, or custom GEO workflow platforms that convert citation gaps into implementation tasks automatically. The response includes gap priority scoring (commercial impact ranking), estimated time to citation improvement for each recommended gap-closing investment, and links to the relevant Onxeera GEO Guide chapters covering each recommendation.
Webhook Support
The Onxeera API supports webhooks for citation rate events — enabling real-time notifications when citation rate changes exceed configured thresholds. Configure webhook endpoints to receive POST notifications when: a citation rate regression is detected (overall citation rate drops by a specified threshold), a new citation is earned for a previously uncited query, a competitor citation rate change exceeds a monitoring threshold, or a scheduled monthly citation report is complete. Webhook notifications enable event-driven GEO monitoring — triggering automated responses (Slack alerts, Jira tickets, email notifications) when citation events occur rather than requiring manual dashboard checks.
Developer Use Cases
Unified Marketing Dashboard Integration
The most common developer use case for the Onxeera API is integrating AI citation data into a unified marketing performance dashboard — pulling citation rate data alongside Google Analytics organic traffic, Google Search Console ranking data, and paid search performance metrics into a single dashboard that shows total search presence across traditional and AI channels simultaneously. The API’s JSON responses integrate directly with common dashboard tools including Looker Studio, Tableau, Power BI, and custom React or Vue dashboard builds — enabling marketing teams to view GEO performance in the same interface as all other channel performance data without switching between Onxeera and other reporting tools.
Agency White-Label Reporting Automation
GEO agencies use the API to automate client citation rate reporting — pulling citation data for multiple client accounts into a centralized reporting system that generates branded monthly GEO performance reports automatically. The API’s multi-brand support (each API key can access data for all brands configured under the Onxeera account) enables agencies to pull citation data for all clients in a single integration, process the data through their report generation system, and deliver client-ready GEO performance reports without manual data collection or report assembly. Agencies managing 10 or more GEO clients report saving 20 to 40 hours per month in citation data collection and report preparation time after API integration.
GEO Workflow Automation
Technical marketing teams use the API’s gap analysis endpoint and webhook support to build automated GEO workflow systems — where citation gaps and regression events automatically generate implementation tasks in project management tools (Jira, Asana, Linear, Notion) and trigger notifications in team communication tools (Slack, Teams). A webhook configured to fire when a new citation gap appears (a query that was previously cited and is now not) automatically creates a “investigate citation regression” task in the team’s project management system, assigns it to the GEO lead, and sets a 48-hour resolution deadline — converting the manual process of monitoring citation rates into an automated, accountability-tracked workflow.
Getting Started
The Onxeera API uses standard REST conventions with JSON request and response bodies and API key authentication. Authentication is handled through a bearer token passed in the Authorization header of each request — API keys are generated in the Onxeera dashboard under Settings → API. All API endpoints are documented at onxeera.com/api-docs with full request and response schemas, example code in Python, JavaScript, and cURL, and an interactive API explorer that allows testing endpoints directly from the documentation page without writing code. The API documentation includes a quickstart guide covering the 5-minute setup from API key generation through your first citation rate API call — designed for developers who want to validate the integration before investing in a full dashboard build.
Rate Limits and Plans
| Plan | API Access | Monthly API Calls | Endpoints Available |
|---|---|---|---|
| Starter | No | — | — |
| Growth | Yes | 500 calls/month | Citation Rate, Citation History |
| Agency | Yes | 5,000 calls/month | All endpoints + Webhooks |
| Enterprise | Yes | Custom | All endpoints + Webhooks + Priority support |
API calls that trigger fresh citation tests (on-demand citation rate requests) count as 1 call per query tested per platform — a 20-query test across 4 platforms uses 80 API calls. Historical data requests and gap analysis requests that return stored data count as 1 API call regardless of the data volume returned. Webhook deliveries do not count against the monthly API call limit.
FAQs
What authentication method does the Onxeera API use?
The Onxeera API uses API key authentication — each request includes an API key as a bearer token in the Authorization header. API keys are generated in the Onxeera dashboard under Settings → API and can be revoked and regenerated at any time. Each Onxeera account can have multiple API keys — enabling separate keys for production and development environments, or separate keys for different integrations within the same account. API keys have configurable permission scopes — read-only keys (for dashboard integrations that only pull data) and full-access keys (for integrations that also trigger citation tests) can be configured separately.
Can I use the API to trigger citation tests programmatically?
Yes — the Citation Rate endpoint supports on-demand citation test triggers via API, allowing you to initiate a fresh citation test programmatically and receive results when the test completes (typically within 30 to 60 seconds for query sets of 20 queries or fewer). On-demand test triggers are useful for automated testing workflows — running citation tests after content deploys, schema updates, or other GEO implementation events to verify that changes have been indexed and citation improvements are appearing. On-demand tests count against your monthly API call limit based on the number of queries and platforms tested.
Is there a free API tier?
API access is available on Growth plan and above — there is no free API tier. Developers who want to evaluate the API before upgrading can use the Onxeera dashboard’s export functionality (CSV and PDF exports of citation data) as a manual alternative to API integration. The full API documentation and interactive API explorer at onxeera.com/api-docs are publicly accessible without authentication — allowing developers to review the full API specification and test endpoint schemas before committing to an API-enabled plan upgrade.
