What You Can License

Two APIs, both centered on your own signal layer

The offer is built around uniquely generated 4starter output. That keeps the product legally cleaner and operationally lighter than exposing vendor-heavy pages directly.

Ticker Signal API

Per-ticker proprietary 4starter output

Built for watchlists, product pages, and lightweight alerts. It exposes your proprietary signal layer, not raw third-party market data.

Core fields
tickermarketsignalsignal_scoresignal_updated_at
Recommended refresh: max once per 60 seconds per ticker.
Example request
GET /api/v1/ticker-signal?ticker=AAPL
Example response shape
{
  "ticker": "AAPL",
  "market": "NASDAQ",
  "signal": "buy",
  "signal_score": 82,
  "signal_updated_at": "2026-04-02T08:15:00Z"
}
Market Signals API

Batch market feed for efficient sync

Pull one market snapshot and receive the latest proprietary signal output for every covered ticker in that market.

Core fields
marketas_oftickers[].tickertickers[].signaltickers[].signal_scoretickers[].signal_updated_at
Recommended refresh: max once per 5 minutes per market. Use limit and offset for larger snapshots.
Example request
GET /api/v1/market-signals?market=NASDAQ&limit=500&offset=0

Who It Is For

Built for teams that want signal value, not a raw-data vendor relationship

The strongest buyers usually want a reusable decision layer inside an existing product, service, or internal workflow. These are the clearest fits.

Investing apps

Watchlists, member products, and stock-detail experiences

Add a proprietary conviction layer to stock pages, watchlists, and logged-in product surfaces without building your own scoring system first.

Best when you want faster product shipping and a clearer premium layer.
Advisor portals

Client dashboards, advisor tools, and premium account views

Use compact signal output inside client or advisor workflows where the signal supports a broader service, not a standalone trading terminal.

Best when the API strengthens an existing relationship product.
Content and SEO

Stock landing pages, widgets, and conversion surfaces

Use lightweight ticker calls behind stock pages, content modules, or widgets that need a small proprietary signal layer to improve engagement and conversion.

Best when you want product-led acquisition without exposing heavy vendor data.
Internal systems

Analyst, support, sales, and operations tooling

Give internal teams the same signal layer across review tools, QA flows, editorial checks, or operational dashboards that need consistent output.

Best when consistency matters more than raw market exhaust.

Commercial Confidence

Built to feel workable from the first subscription onward

The API is not just a price list. Buyers need to know how access is provisioned, how testing works, and how the billing path scales as usage grows.

Provisioning

Subscriptions issue working account access

The paid plan is tied to account-level billing and API-key provisioning, so customers move from checkout to usable access without a manual handoff.

Testing

Live request examples are part of the member flow

Subscribers can copy the key, test a real request, and review implementation examples directly from the member side of the page.

Billing

Managed upgrades fit product growth

Customers can start lower, move up the plan ladder, and manage the billing path as product volume and coverage requirements expand.

Delivery

Controlled usage is part of the product design

Credits, limits, caching, and market-level batching are presented as delivery discipline, not as an afterthought once usage starts.

Ways To Use It

Built for products, automations, and internal signal workflows

The API is most valuable when it becomes a decision layer inside a product or process. These are the main ways teams typically use it without turning it into a raw-data mirror.

Member product

Watchlists, dashboards, and account experiences

Use the ticker endpoint to place a proprietary 4starter signal layer inside logged-in watchlists, customer dashboards, and account-level stock views.

Best fit Retail products that need one symbol at a time
Delivery pattern On-demand ticker lookup with short local cache
Automation

Alerts, notifications, and workflow triggers

Feed email, push, Slack, or CRM workflows when a tracked market or ticker changes signal state and your own system decides who should receive it.

Best fit Trigger-based messaging and customer automation
Delivery pattern Scheduled market snapshots plus your own diff logic
Research UI

Screeners and market overview pages

Show broad market signal coverage in one view without polling large ticker lists individually. This is where the market endpoint saves the most load.

Best fit Products that need broad market coverage in one pass
Delivery pattern Batch market sync on a fixed schedule
Client portal

Advisor, broker, and private client experiences

Add a compact conviction layer to premium client portals, model portfolios, and advisor dashboards without exposing raw third-party market feeds.

Best fit Commercial portals where the signal is part of a broader service
Delivery pattern Market sync for coverage plus on-demand ticker lookups
Internal tools

Analyst, sales, QA, and operations tooling

Use the same signal layer internally for support teams, analyst review, editorial checks, and operational dashboards that need consistent output.

Best fit Internal software where fast implementation matters more than scale
Delivery pattern Server-to-server calls with low concurrency
Content layer

Website cards, widgets, and conversion pages

Place a signal card inside stock landing pages, campaign pages, or publisher-style content blocks where a lightweight proprietary view improves conversion.

Best fit Sites that need a small signal surface, not a full trading stack
Delivery pattern Server-rendered ticker calls with page cache in front
Implementation Lanes

Three clean ways to run the API without wasting credits

Most customers fit one of these patterns. The strongest integrations usually combine one scheduled sync path with a smaller on-demand lookup layer.

On-demand lookup Call the ticker endpoint when a user opens a page, expands a row, or requests a fresh symbol view.
Scheduled market sync Run the market endpoint on a timed job, cache the result internally, and serve your own app from that local copy.
Hybrid product model Use market sync for broad coverage, then use ticker calls only for high-intent user actions and detail views.

Go Live

From account to working integration in three clean steps

The page is designed for fast evaluation: pick a plan, receive the key, test a live request, then move the integration into your own product flow.

01

Choose the plan that fits your product

Start with Builder for narrower products, Growth for broader market sync, or Platform when you need heavier commercial usage.

02

Receive the key and run a live call

The subscription provisions an API key, shows it in your account, emails it to you, and gives you an immediate live AAPL test path.

03

Move into production and upgrade as you grow

Use ticker calls for detail views, market snapshots for sync jobs, and move up the plan ladder through managed billing when volume grows.

Credit rules: 1 ticker lookup = 1 credit. 1 market snapshot = 25 credits. Hard monthly caps are intentional.

Rate Limits

Delivery rules that protect the server

This is the commercial logic behind the pricing. It is built to stop clients from turning the API into a polling storm.

Rolling minute limit

Every plan has a requests-per-minute ceiling. Exceed it and the API should return 429 with reset information.

Concurrency cap

Limit simultaneous in-flight requests per API key so one customer cannot open dozens of workers.

Server-side cache windows

Ticker responses can be cached for 60 seconds and market snapshots for 300 seconds so repeated calls stay cheap.

Monthly hard ceiling

Plans stop at the included credit limit unless approved overage is enabled.

FAQ

Common commercial questions

What data is included in the API license?

The API is intended for proprietary 4starter outputs such as signal state, score, market classification, and update time.

Why use credits instead of unlimited requests?

Credits price light integrations fairly while protecting the platform from abusive polling.

How should clients poll the API?

Use the ticker endpoint sparingly for on-demand lookups and the market endpoint for scheduled sync.

Can I redistribute the API as raw data?

No. Redistribution, open mirrors, and bulk raw-data resale require separate written approval.

Next Step

Start with the plan, then scale into the right integration model.

If you already know the fit, start with Builder, Growth, or Platform. If you want guidance first, share your use case, expected volume, and target markets.
