S&P Stocks Ratings & Charts API integration (StockRing OpenData)

Stock ratings engine

A structured endpoint returning the current rating per ticker, the intraday update timestamp, and the delta from the previous refresh. Feeds alerting, portfolio risk flags, and "new Buy" email digests without polling the mobile UI.

Rating history export

The same days / weeks / months history the app shows for accuracy validation, returned as paginated JSON. Drives backtests, compliance reviews, and public dashboards that publish verified hit-rates.

Watchlist & filter state

Read the end user's watchlist in the order they've sorted it (daily gains, trading volume, volatility), plus saved filters such as "show only Grab or Buy". Useful for advisor-client mirroring and wealth-platform onboarding.

Charts & technicals

Weekly, monthly, and multi-year OHLC series with pre-computed moving averages. Serves internal charting tools, embedded ticker widgets, and risk models that need the same smoothing the app displays.

Fundamentals & profile

Dividends, debt, income, volatility, revenue, earnings dates, EPS, plus the company's business description. Feeds research notes, CRM enrichment, and KYB workflows that need a quick ticker overview.

AI-curated news stream

Top Stories and per-ticker news as selected by the app's algorithms — tagged with publisher, publish time, and related ticker list. Powers compliance surveillance, investor-relations feeds, and sentiment scoring.

1 · Advisor watchlist mirroring

Business context: A registered investment advisor wants to see the same watchlist their retail client sees inside the StockRing app.
Data / API: authenticated /watchlist read plus per-ticker rating lookup.
OpenFinance mapping: behaves as a read-only user-consented data share, similar to account-information flows in Open Banking, but applied to the personal investment research layer.

2 · Backtest & accuracy reporting

Business context: A fintech wants to publish a monthly "hit rate" chart showing how often Buy and Grab signals preceded positive returns.
Data / API: /ratings/history paginated by ticker and date.
OpenFinance mapping: consumes the app's own validation surface as a reusable dataset for compliance and marketing disclosures.

3 · Alerting & push-notification fan-out

Business context: A trading desk wants a Slack / email / SMS fan-out any time a watched ticker moves from Hold to Grab.
Data / API: webhook subscription on rating transitions with before / after fields.
OpenFinance mapping: event-driven pattern, analogous to transaction webhooks in Open Banking, but applied to equity signals.

4 · Research-desk enrichment

Business context: Sell-side analysts need fundamentals plus the AI news stream next to their internal notes.
Data / API: combined /fundamentals and /news endpoints scoped to a ticker list.
OpenFinance mapping: plays the role of a licensed data product — consumer pulls authorized fields only, logs each access for audit.

5 · Cross-app portfolio unification

Business context: A user already tracks equities across TipRanks and Yahoo Finance; they want a single rating view that also incorporates the StockRing verdict.
Data / API: ticker search + rating lookup, matched on CUSIP / symbol.
OpenFinance mapping: aggregator pattern, consolidating multiple user-authorized sources into one view.

Auth & session bootstrap

POST /api/v1/stockring/auth
Content-Type: application/json

{
  "client_id": "studio_xxx",
  "grant_type": "device_session",
  "device_profile": "pixel_8_android14"
}

200 OK
{
  "access_token": "eyJhbGciOi...",
  "expires_in": 3600,
  "scope": "ratings watchlist fundamentals news"
}

Mirrors the authorization handshake the mobile client uses; tokens are rotated and bound to a device profile so access can be revoked per engagement.

Rating history query

GET /api/v1/stockring/ratings/history
  ?symbol=MSFT
  &from=2025-10-01
  &to=2025-12-31
Authorization: Bearer <ACCESS_TOKEN>

200 OK
{
  "symbol": "MSFT",
  "index": "S&P 500",
  "series": [
    { "ts": "2025-12-30T14:30:00Z", "rating": "BUY",  "prev": "HOLD" },
    { "ts": "2025-12-30T18:00:00Z", "rating": "GRAB", "prev": "BUY"  },
    { "ts": "2025-12-30T20:45:00Z", "rating": "GRAB", "prev": "GRAB" }
  ]
}

Each day returns up to three rating snapshots aligned with the app's intraday refresh cadence.

Rating-change webhook

POST https://your-stack.example.com/hooks/stockring
X-Signature: sha256=...
Content-Type: application/json

{
  "event": "rating.transition",
  "symbol": "NVDA",
  "from":   "HOLD",
  "to":     "GRAB",
  "ts":     "2026-04-23T18:00:00Z",
  "index":  "S&P 500"
}

Error handling: retries with exponential backoff up to 5 attempts;
dead-letter queue on non-2xx responses for replay.

Event-driven pattern for alerting stacks; signatures let you verify payloads and reject replays.
