Usage-based spend control

Stop surprise usage bills before they hit your runway.

Outlayo intercepts app-side API usage, turns it into spend signals, and reconciles it with vendor data where trustworthy billing feeds exist.

Request early access Explore the OSS repo

Built for startup founders, indie hackers, and infra-minded teams running OpenAI, cloud infra, and usage-priced APIs without a single source of truth.

Instrument in minutes

Show teams how little code it takes.

Add the ingest SDK, pass its tracked fetch into the client you already use, and start emitting usage events before you wire up any vendor reconciliation.

1. Install @outlayo/sdk-ingest and add the OpenAI preset.

2. Hand Outlayo's tracked fetch to your OpenAI client.

3. Emit usage events to your Outlayo collector while connector reconciliation catches up later.

Example

npm install @outlayo/sdk-ingest openai

import OpenAI from "openai";
import { setupPresetFetch } from "@outlayo/sdk-ingest";

const outlayo = setupPresetFetch({
  presets: [{ name: "openai" }]
});

const openai = new OpenAI({
  apiKey: process.env.OPENAI_API_KEY,
  fetch: outlayo.fetch
});

await openai.responses.create({
  model: "gpt-4o-mini",
  input: "Draft a refund response for this ticket"
});

Differentiator

Coverage without waiting on vendors

Intercept real application traffic first, so weak billing APIs do not block visibility.

Reconciliation

Authoritative where possible

Pull vendor telemetry where reliable feeds exist to reconcile estimates against stronger signals.

Action

Alert before margin slips

Forecast budget and free-tier breaches, then push webhook alerts before invoices turn into surprises.

Why technical teams switch

One model for live usage, spend, and confidence

Ingest-first coverage for real-world vendor gaps

Preset extractors plus connector reconciliation

Built-in export, dashboarding, and webhook automation

Open Source + Hosted, clearly separated

OSS repo: connectors, core packages, docs, and contributor workflows

Hosted app: managed service access at app.outlayo.com

Public code: transparent runtime and integration logic

Private ops: secrets, production infra state, abuse controls, tenant operations

Instrument one costly workflow this week.

Start with app-side interception, then layer in connector reconciliation where vendor telemetry is strong.
