Developer Preview

Sterling's data and AI, in your product.

A single API for company financials, sector intelligence, and grounded AI Q&A. Built for fintech teams that don't want to assemble it themselves.

What you can build

Three patterns we see today

Most partners start with one of these and grow into the others over time.

Embedded research

Drop Sterling charts into your client portal. Two-line iframe or component-level integration via the SDK.

AI assistant for finance

Ground your chatbot in real SEC filings and quarterly numbers. We handle retrieval and source attribution.

Sector and KPI feeds

Pull Sterling's sector intelligence and curated operational KPIs into your own dashboards. Read-only JSON.

API surface

The v1 plan

None of these endpoints are live yet. This is the surface we are building with design partners. Order and shape will move based on partner feedback.

POST/v1/ask
Ask Sterling AI. Streaming JSON with source citations on every claim.
GET/v1/sectors
Sector list with editorial dashboards and representative companies.
GET/v1/sectors/{slug}
Single sector. Strategy commentary, KPIs, ranked competitive view.
GET/v1/companies/{ticker}/kpis
Sterling-curated operational KPIs. Tesla deliveries, iPhone units, energy storage MWh, and similar.
GET/v1/filings/{accession}
Parsed SEC filing data with extracted figures and tables.
POST/v1/webhooks
Subscribe to events: new filings parsed, new KPIs landed.

What is not in the API

Raw quarterly financials (income statement, balance sheet, cash flow) are not available as JSON endpoints. Our financial data is licensed under terms that do not allow API redistribution. If you need these in your product, get in touch and we will talk through the options.

Try it

A request looks like this

Design-partner preview. Live keys provisioned at kickoff.

curl

curl https://api.sterlingcharts.com/v1/ask \
  -H "Authorization: Bearer sk_live_..." \
  -d '{"q":"Tesla auto margin last 4 quarters?"}'

TypeScript SDK

import { Sterling } from "@sterlingcharts/sdk";

const sterling = new Sterling({ apiKey });
const answer = await sterling.ask(
  "Tesla auto margin last 4 quarters?",
);

SDKs and docs

Tooling for the integration

TypeScript SDK

Coming with v1

npm install @sterlingcharts/sdk. Typed responses, retries, streaming for AI endpoints.

OpenAPI spec

At kickoff

Generated from source. Compatible with any code generator. Use it to wire up clients in any language.

Integrations

Where Sterling shows up

The API is the foundation. These are the surfaces we are building on top of it. Vote with your design-partner application: integrations with the most partner demand ship first.

Slack

Planned

Daily digests and AI Q&A from an /ask slash command.

Notion and Coda

Planned

Embedded charts that update live alongside your docs.

Excel and Google Sheets

Planned

Pull Sterling-curated KPIs and AI answers into a cell with a custom function.

Zapier

Planned

Trigger workflows when a filing lands or a tracked KPI updates.

Push, not just pull

For partners who want to react to events rather than poll, signed webhooks fire when a new SEC filing is parsed or fresh quarterly numbers land. Subscribe per event type, with HMAC signatures and replay protection.

Frequently asked

Common questions

Is there a free tier?

Design partners get year one free. After that, usage-based pricing kicks in. Final per-request pricing will be set before public launch.

Why aren't quarterly financials in the API?

Our financial data is licensed under terms that do not allow API redistribution. If you need income statement, balance sheet, or cash flow data in your product, get in touch and we will talk through the options.

Can I self-host?

No. Sterling's data pipeline is the product. We host the API and the underlying ingest.

What are the rate limits?

Per-key, per-endpoint. Defaults will be published in the docs. Design partners get raised limits as part of the program.

How fresh is the data?

SEC filings ingested within minutes of release. Sterling-curated KPIs updated each reporting period. AI answers reflect data as of the last ingest.
