API Funnel is a no-code visual platform for aggregating multiple internal and external API endpoints into one unified API, without writing any code. You drag Input nodes onto a canvas (each connecting to a different API), wire them to an Output node, map the fields you want, and publish a single clean endpoint in minutes. It is purpose-built for API aggregation and data merging, not general-purpose workflow automation.

How do I aggregate multiple API endpoints without writing code?

With API Funnel you can aggregate multiple API endpoints without code in four steps: (1) Create a canvas and add Input nodes, each Input node connects to one of your APIs (REST, GraphQL, SOAP, or gRPC). (2) Add an Output node to define your unified endpoint path. (3) Map and transform the response fields you want from each input into the output schema using the visual field mapper. (4) Click Publish. API Funnel merges all the upstream responses and serves the combined result as a single live API endpoint.

Can I combine internal APIs and external APIs in the same endpoint?

Yes. API Funnel is specifically designed for combining internal and external APIs in a single workflow. Each Input node independently calls any URL you provide, your own private internal services (authenticated with Bearer tokens, API keys, or Basic auth) alongside public third-party APIs. The Output node merges the responses into one unified result your clients query.

How does API Funnel compare to Make (Integromat) or Zapier for API aggregation?

Make and Zapier are event-driven workflow automation tools, they trigger actions in response to events (a new row, a form submission, an email). They are not designed to create a live, queryable API endpoint that merges multiple data sources on demand. API Funnel is built specifically to publish a single merged API endpoint that external clients, AI agents, or frontend apps can query at any time. If you need 'when X happens, do Y', use Make or Zapier. If you need 'I want one endpoint that aggregates data from multiple APIs and returns it on request', use API Funnel.

How does API Funnel compare to n8n for merging API responses?

n8n is a self-hosted workflow automation tool with a visual node editor. Like Make and Zapier, it focuses on event-driven pipelines. It can be used to merge API responses as part of a workflow, but it requires self-hosting, technical setup, and does not natively publish a persistent, queryable REST endpoint. API Funnel is cloud-hosted with zero infrastructure, and its core output is a live API endpoint your clients can query directly, not a triggered workflow execution.

How is API Funnel different from MuleSoft or Boomi?

MuleSoft and Boomi are enterprise iPaaS platforms requiring dedicated engineers, months of implementation, and five-to-six figure contracts. API Funnel is a self-serve no-code tool designed for developers, product teams, and non-technical builders who want to aggregate and publish APIs in minutes without enterprise infrastructure. API Funnel deploys in minutes versus months.

What API types does API Funnel support for aggregation?

API Funnel supports REST (JSON), GraphQL, SOAP/XML, and gRPC as input sources. You can mix and match, for example, fetch data from a REST API and a GraphQL API simultaneously, merge the responses, and publish a single clean REST endpoint as the output.

Can I transform and reshape API response data before publishing?

Yes. API Funnel includes a visual field mapper where you select which fields from each upstream API response to include in your output, rename them, apply transformers (flatten, unique, reverse, slice, sort, pluck), set conditional values, and define fallback defaults. No code required.

Does API Funnel work as a no-code API gateway?

API Funnel functions as a no-code API gateway for aggregation use cases, it sits between your clients and multiple upstream APIs, aggregates and transforms the responses, and serves a single unified endpoint. It includes rate limiting, caching, authentication forwarding, retry logic, and custom domain support that are typical of API gateway features.

Can API Funnel endpoints be used as tools for AI agents and LLMs?

Yes. API Funnel publishes MCP-compatible endpoints that AI agents and LLMs can call as tools via tool-use / function-calling. You can aggregate multiple data sources and expose the merged result as a single clean tool endpoint for Claude, GPT-4, or any other LLM that supports tool calling.

How much does API Funnel cost?

API Funnel offers three plans: Starter at $9/month (10 endpoints), Professional at $39/month (25 endpoints with custom domains), and Business at $99/month (100 endpoints with security controls and audit logging). All plans include a free trial period.

Can I try API Funnel for free?

Yes. API Funnel offers a free trial period where you can build and publish aggregated API endpoints using all Starter plan features before committing to a paid subscription. No credit card required during the trial.

API Funnel vs Postman

Postman is an API testing and documentation tool. API Funnel is an API building and publishing tool. Postman helps you work with APIs that already exist. API Funnel helps you create and publish APIs that did not exist before.

View Pricing

What is Postman?

Postman is the industry standard tool for testing, documenting, and collaborating on APIs. You send requests to existing endpoints, inspect responses, write tests, and share collections with your team.

What is API Funnel?

API Funnel is a visual API builder. You drag nodes onto a canvas, connect them, and publish a live REST API endpoint - no code required. You are not testing an API - you are creating one.

Side-by-side comparison

	Postman	API Funnel
Primary use case	Test and document existing APIs	Build and publish REST APIs
Creates endpoints	No	Yes
No-code	Partial (tests require scripting)	Yes
Visual canvas	No	Yes
API documentation	Yes	No
Collaboration	Yes	Yes (real-time)
For developers	Yes	Yes
For non-developers	No	Yes
Best for	Testing and documenting existing APIs	Building APIs from scratch visually

When to use Postman

You have an existing API and need to test, debug, or document it
You want to share API collections with your team
You need automated API testing in your CI/CD pipeline

When to use API Funnel

You need to build a new API endpoint without writing backend code
You want to publish a live REST API visually
You are connecting data sources or services into a single callable endpoint
You are building for AI agents or automated systems that need a real API

Can you use both?

Yes - and it makes sense to. Build and publish your API in API Funnel, then use Postman to test and document it. They complement each other well.

Bottom line

Postman is the best tool for working with APIs that exist. API Funnel is for when the API does not exist yet and you need to build it - fast, visually, without code.

Compare API Funnel to other tools

API Funnel vs Zapier

Zapier automates workflows between apps. API Funnel lets you build and publish APIs visually. They solve different problems - but if you need a live, callable API endpoint rather than a trigger-based automation, API Funnel is the right tool.

API Funnel vs Make

Make (formerly Integromat) is a visual workflow automation tool. API Funnel is a visual API builder. Both are no-code and canvas-based - but Make automates processes between apps, while API Funnel publishes live endpoints that anything can call.

Read comparison

API Funnel vs RapidAPI

RapidAPI is a marketplace where you discover and consume APIs built by others. API Funnel is where you build and publish your own. They sit at opposite ends of the API lifecycle.

Read comparison

API Funnel vs Pipedream

Pipedream is a developer-focused workflow automation platform with code support. API Funnel is a visual API builder with no code required. Pipedream gives developers flexibility in automation. API Funnel gives anyone the ability to publish a live API endpoint.
