Public APIs Integration for Custom Data Sources
Connect any REST API and let AI agents query custom data sources alongside marketing platforms—no coding required.
Key Takeaways Connect any public API automatically
Improvado connects to any REST API to extract data automatically, whether it's a custom internal API or third-party public service. Configure authentication, endpoints, and data mapping through our interface without coding. The integration handles rate limiting, error handling, and data validation automatically. Schedule extractions to keep your API data current across all sources.
Normalize custom API data with marketing platforms
Improvado's Marketing Common Data Model transforms custom API data into standardized formats alongside your existing marketing platforms. Map API fields to common schemas, combine disparate data sources, and create unified analytics views. Your custom API data flows into the same warehouse as Google Ads, Salesforce, and 500+ other pre-built connectors.
Data objects and fields Improvado extracts from Public APIs
| Object | Fields |
|---|---|
| [VERIFY] Custom Endpoint | user-defined fields vary by API |
| [VERIFY] Response | string number boolean array object |
| [VERIFY] Metadata | endpoint method status_code |
From connection to autonomous action in three steps
Connect
Connect your API management platform via API key or OAuth. The agent authenticates with read and write permissions to access endpoint configurations, usage metrics, and rate limit controls.
Ask
Ask questions like 'Which endpoints are approaching rate limits?' or 'Show me API usage by client application for the last week' or 'What's the P95 latency for authentication endpoints?'
Act
The agent adjusts rate limits, updates endpoint throttling rules, configures alert thresholds, generates API keys for new clients, and modifies authentication policies based on usage patterns.
What teams ask their AI agent about Public APIs
Real prompts from enterprise marketing teams. The agent reads your data, answers in seconds, and takes action when you ask.
Combine proprietary data APIs with marketing platforms for complete attribution
Your AI agent analyzes Public APIs data and delivers actionable insights — automatically, in seconds.

Your AI agent analyzes Public APIs data and delivers actionable insights — automatically, in seconds.
Build executive dashboards combining internal APIs with external marketing data
Your AI agent analyzes Public APIs data and delivers actionable insights — automatically, in seconds.
Your agent doesn't just read APIs — it combines proprietary data with marketing
Read
The agent reads endpoint performance metrics, request volumes, error rates, response times, rate limit utilization, client authentication logs, API version adoption, payload sizes, and geographic request distribution.
Write
The agent updates rate limits, modifies throttling policies, generates and revokes API keys, adjusts endpoint configurations, updates CORS policies, and implements IP whitelisting rules.
Monitor
The agent monitors error rate spikes, latency degradation, rate limit breaches, authentication failures, unusual traffic patterns, endpoint deprecation timelines, and API version migration progress.
AI agents query any configured REST endpoint, from internal tools to third-party services, using natural language. They can pull competitor data, combine proprietary metrics with ad spend, and build attribution models across custom and standard sources. The agent handles authentication, rate limits, and data validation while answering complex cross-platform questions.
