Keep your APIs from breaking the code that depends on them.
Source Dialogue connects what changed in an API with how your code actually uses it — then gives your coding agent the context and instructions to make the fix, run your checks, and open a tested PR for review.

An API change has two sides.
If you build the API
Your team has the best context on what changed in your API and why.
What's harder is knowing which customers depend on that behavior, where those dependencies live in their code, and what needs to change downstream.
Documentation and changelogs communicate the change. They don't update the code that depends on it.
If your product depends on APIs
You know how your code uses them.
Even when a change is documented, someone still has to determine whether your implementation is affected and what needs to change.
Your coding agent can fix the code. First, it needs to know what changed, whether your code depends on it, and what a correct migration requires.
Source Dialogue connects those two pieces of information.
// how it works
From API change to a ready-to-review PR.
Understand what changed
Source Dialogue starts with the best available information about what changed — from vendor updates and other change signals, and, where API teams participate directly, richer context from the source.
Find the code that depends on it
Source Dialogue checks that change against how your software actually depends on the API.
The goal isn't to alert everyone. It's to identify the integrations that are actually affected — and give each one the context needed to fix the change.
Give the coding agent the context to fix it
Source Dialogue sends the affected team's coding agent the change context and maintenance instructions it needs. Working inside the permissions and development workflow that team has approved, the agent can inspect the implementation, create the change, run the required checks, and open a tested PR for review.
Source Dialogue is being designed to work with coding environments like Claude Code first, with other coding agents following.
// product example
One change. Only the affected teams hear about it.
Suppose your API stops accepting source and now requires payment_method.
A normal changelog tells every customer that the API changed.
Source Dialogue asks a different question:
Who actually relies on source today?
It can identify the affected integrations, give each team's coding agent the relevant migration context, and let the agent work from the customer's own codebase.
POST /paymentssource in 3 call sitessourcepayment_method// for api teams
Ship changes with a better understanding of who they affect.
When your API changes, Source Dialogue turns the available change context into something downstream coding agents can act on. When you participate directly, you can give Source Dialogue richer context about what changed, why it changed, and how customers should migrate.
That can mean identifying:
- what behavior changed
- which endpoints, SDK methods, fields, or assumptions are affected
- whether the change is breaking or compatible
- when it takes effect
- what a customer needs to do differently
Source Dialogue then connects that change to participating customers' actual usage — instead of treating every release note as equally relevant to everyone.

Stop discovering API changes after they become your problem.
Your team already has coding agents that can understand and modify your code.
Source Dialogue gives those agents something they're usually missing: reliable context about changes upstream and whether those changes affect your implementation.
Instead of asking an agent to continuously monitor the entire API ecosystem and guess what matters, Source Dialogue connects upstream change information to the API usage your team has already identified.
When something is relevant, your coding agent can inspect the local implementation, determine the correct fix, run your existing validation, and propose the change.
Pilot Source Dialogue with your codebase// why not just use a coding agent
Your coding agent can fix the code. Source Dialogue tells it what changed.
Your coding agent can understand your code and make the fix.
What it usually lacks is reliable context about changes upstream: what changed, whether your implementation depends on it, and what a correct migration requires.
Source Dialogue supplies that missing maintenance context and the instructions to act on it — so the agent can turn a relevant API change into a tested PR.
// security
Built around the code-access boundary.
Your coding environment does the code-level work.Source Dialogue is being designed to work with coding agents operating inside the environments where your code already lives.
Minimize what has to leave your environment.The central service can work from structured information about API changes and API usage rather than requiring a central copy of every participating repository.
You control what the agent can do.Read scope, stored information, code changes, testing, and PR permissions can be constrained to the access your team is comfortable granting.

Help us build the maintenance layer between APIs and the code that depends on them.
We're looking for the first API teams and engineering teams to build this with us — design partners who want to help shape the access, security, and workflow boundaries for self-maintaining APIs.
If you maintain an API used by other companies — or maintain software that depends heavily on third-party APIs — we'd like to work with you.
Early pilots will help shape what Source Dialogue reads, what it stores, when it acts, and how fixes enter your development workflow.
