Go Beyond Just Documentation:
Get a Self-Serve Developer Experience with DigitalAPI

A developer's path from first click to first production call involves rich documentation as documentation. DigitalAPI not only does that as well as Swagger or Stoplight, but steps two through six are where docs-only tools stop and DigitalAPI shines.

Why Should You Choose DigitalAPI Over Swagger UI?

Swagger hub is great at documentation but journey ends roughly where the developer says "okay, now how do I actually use this?".
DigitalAPI is what every enterprise API program needs after: self-serve signup, sandbox, key lifecycle, partner onboarding, governance and AI exposure.

Centralized API Catalog Across Gateways and BUs

One self-serve catalog for APIs scattered across Apigee, Kong, Azure and every BU. Consistent search, governance and discovery, instead of three docs portals and a Confluence page nobody updates.

Lifecycle and rotation built in

Set per-user key rotation policies (90, 120, 180 days, your call), automated reminders before expiry, audit-ready logs. The platform enforces the policy; your engineers don't.

Self-serve sign-up, sandbox and SSO

Internal and external developers, consumers, and partners sign up via SSO, create an app, get credentials, and make a first sandbox call in minutes. No tickets, no Word docs, no manually issued keys.

DigitalAPI Combines Docs and Self-Serve in the Same Platform

It includes everything a docs portal gives you, and adds the self-serve layer above your gateway, turning every API into something a developer can find, sign up for, try, and ship without a human in the loop.

Rich Documentation, the Foundation

OpenAPI rendering, embedded videos, getting-started guides, FAQs, changelogs, support content, code samples in multiple languages. Docs is the starting line, and we run it well.

Interactive API explorer and sandboxing

Get an interactive sandbox inside the portal with pre-filled auth tokens, saved history, and shareable examples. Collapses the gap from "discovered the API" to "made the first call" from days to minutes.

AI-Ready: Native MCP Layer for LLM Agents

Expose your APIs as tools to LLMs and agent frameworks, with scoped credentials, rate limits and audit trails. When LLM-based consumption hits in the next two to three years, the wiring is in place.

Sits on top of your gateway, No rip-and-replace

Keep your existing OpenAPI specs, Stoplight design workflows, and Apigee, Kong, AWS or Azure APIM gateway. DigitalAPI is the consumer-facing self-serve layer above them, not a replacement for any of them.

Extensible: Webhooks, Iframes, Ticketing, MCP

Developers can sign up with SSO, create an app, get credentials, and makes a first sandbox call in minutes be it an internal engineer, external developer, or a partner.

One API Platform for Internal, Partner, and External Consumption

Most API tools force a choice: internal developer experience, partners or an external one.
DigitalAPI runs all three on the same catalogue, with different identity, access and visibility rules per audience.

Engineering teams across BUs

Discover and consume APIs published by other teams in the same enterprise without raising a ticket.

Contracted consumers and Partners

Banks, insurers, fintechs, distributors. Approval-gated access with contract-bound tiers and audit.

Native MCP layer for LLM agents

Anyone on the internet. Sandbox access, plan upgrades, and an MCP-exposed surface for agents.

Self-Serve Helps Both the API Provider and the API Consumer

Most API tools force a choice: internal developer experience, partners or an external one.
DigitalAPI runs all three on the same catalogue, with different identity, access and visibility rules per audience.

[For API Providers]

Stop Being the Credentials Helpdesk!

Ship a branded, self-serve portal in two to six weeks, not a twelve-month build. Sign-up, keys, rotation and partner onboarding all run themselves, so your platform team stops being the credentials helpdesk.

[For API Consumers]

Sign up, get a key, ship before lunch!

Sign up, get scoped credentials, and hit a real sandbox in under five minutes. No ticket, no word document, no sales call. Live dashboards show calls, errors and quota burn once you ship.

Powering Fortune 500 Companies with a Unified API Management Platform

Still using Swagger UI? A docs portal is the starting line, not the finish!

Your developers want sign-up, sandbox, keys and shipping. Your account managers want renewal visibility. Your platform team wants to stop being the credentials helpdesk. None of those needs are met by a Swagger UI page or a SwaggerHub design tool.

DigitalAPI gives you all of that on top of the Swagger or SwaggerHub setup you already run. Same OpenAPI specs. Same gateway. The self-serve layer your developers expected three years ago, ready in two to six weeks instead of twelve to twenty-four months.

Frequently Asked Questions

Other questions?
Get in touch

Is DigitalAPI a Swagger Replacement?

No, and that's the point. DigitalAPI includes everything Swagger UI, SwaggerHub or Stoplight gives you for documentation: OpenAPI rendering, embedded videos, getting-started guides, FAQs, support content, code samples.

Then it adds the self-serve layer on top with sign-up, credentials, sandbox, key lifecycle, partner workflows, governance and AI exposure. You don't replace your docs tool, you replace the gap between your docs and your developers.

What does "self-serve API" actually mean?

It means a developer, internal, partner, or external,. can find your API, sign up, get credentials, hit a sandbox, choose a plan, and ship to production without anyone on your team manually doing anything. No Word docs, no engineer-issued keys, no email threads. Documentation is step one of that journey. The other five steps need a platform.

We are using "Spotlight" today. Do we have to migrate?

No, DigitalAPI imports OpenAPI specs from any source, Stoplight, SwaggerHub, raw repos. Teams that like Stoplight or SwaggerHub for design-first workflows often keep them for that and use DigitalAPI for everything downstream: portal, onboarding, key lifecycle, partner workflows.

Can the same platform serve internal, partner and external consumers?

Yes, that's the design. DigitalAPI runs all three audiences on the same catalogue with different identity, access and visibility rules per audience. Internal consumers get SSO and unmetered access; partners get approval-gated tiered access with sandbox-before-paid; external developers get public self-serve.

Can it handle key rotation policies and lifecycle?

Yes, it supports per-user key rotation policies (90, 120, 180 days, your call), automated reminder workflows before expiry, self-service rotation in the portal, and audit logs. The platform enforces the policy so your engineers don't have to.

Does it integrate with Salesforce for account manager visibility?

Yes, usage data, expiration dates, error patterns and partner activity flow into Salesforce so account managers can manage renewals and intervene on errors without asking the platform team for screenshots

How is DigitalAPI different from an API gateway like Apigee, Kong or AWS?

DigitalAPI is not a gateway. It sits on top of your existing gateway and handles consumer-facing self-serve concerns: developer onboarding, partner management, sandbox, multi-gateway catalogues, and AI agent building. We're an Apigee Premier Partner and we work alongside Kong, AWS, Azure APIM and others.

Can DigitalAPI expose APIs to AI agents?

Yes. DigitalAPI ships with a native MCP layer that exposes your APIs as tools to LLMs and agent frameworks, with scoped credentials, rate limits and audit trails. There's also a no-code visual builder for composing APIs into multi-step agent workflows. Most enterprises won't need this for 2-3 years, but when they do, the wiring is in place.

How long does implementation take?

Most customers go from kickoff to a branded, externally usable self-serve portal in two to six weeks, depending on SSO, branding and integration complexity. A typical in-house portal build is 12 to 24 months
