Market data for
SvelteKit apps.

Use the TickerAPI Node.js SDK in SvelteKit server load functions and API routes. Pre-computed financial data, no infrastructure.

Install the SDK.

Add tickerapi to your SvelteKit project.

terminal
npm install tickerapi

Set TICKERAPI_KEY in your .env file.

Works where SvelteKit runs server-side.

Call the SDK in server load functions and API routes. Data never touches the client bundle.

Server Load Function src/routes/stock/[ticker]/+page.server.ts
import { TickerAPI } from "tickerapi";
const client = new TickerAPI(process.env.TICKERAPI_KEY);

export async function load({ params }) {
  const summary = await client.summary(params.ticker);
  return { summary };
}
API Route src/routes/api/scan/+server.ts
import { json } from "@sveltejs/kit";
import { TickerAPI } from "tickerapi";

const client = new TickerAPI(process.env.TICKERAPI_KEY);

export async function GET({ url }) {
  const sector = url.searchParams.get("sector");
  const results = await client.scan.oversold({ sector });
  return json(results);
}

Track state changes effortlessly.

Most market data APIs return point-in-time snapshots. TickerAPI tracks state transitions — your agent sees what changed, not just what is.

API Route src/routes/api/watchlist/changes/+server.ts
import { json } from "@sveltejs/kit";
import { TickerAPI } from "tickerapi";

const client = new TickerAPI(process.env.TICKERAPI_KEY);

export async function GET() {
  const changes = await client.watchlist.changes();

  // each change includes from/to transitions
  // e.g. trend: "downtrend" → "uptrend"
  return json(changes);
}
json
{
  "ticker": "AAPL",
  "changes": [
    {
      "field": "rsi_zone",
      "from": "neutral",
      "to": "oversold"
    },
    {
      "field": "trend",
      "from": "uptrend",
      "to": "downtrend"
    }
  ]
}

Feed an AI agent.

TickerAPI's categorical output is designed for LLMs. Feed a summary directly into a prompt — the model already understands terms like "oversold" and "strong_uptrend" without extra context.

API Route src/routes/api/briefing/[ticker]/+server.ts
import { json } from "@sveltejs/kit";
import { TickerAPI } from "tickerapi";
import Anthropic from "@anthropic-ai/sdk";

const client = new TickerAPI(process.env.TICKERAPI_KEY);
const anthropic = new Anthropic();

export async function GET({ params }) {
  const summary = await client.summary(params.ticker);

  const msg = await anthropic.messages.create({
    model: "claude-sonnet-4-20250514",
    max_tokens: 1024,
    messages: [{
      role: "user",
      content: `Analyze this stock data:\n${JSON.stringify(summary)}`,
    }],
  });

  return json({ analysis: msg.content[0].text });
}

What your agent sees.

Every tool returns categorical facts — not raw OHLCV data. Your agent can branch on "oversold" without needing to know what RSI > 70 means.

json
{
  "ticker": "NVDA",
  "trend": "strong_uptrend",
  "momentum": {
    "rsi_zone": "overbought",
    "macd_signal": "bullish"
  },
  "volatility": "high",
  "fundamentals": {
    "pe_zone": "above_historical_avg",
    "earnings_surprise": "positive"
  }
}

What you can call.

Every tool returns categorical, pre-computed data. Your agent gets facts it can reason about immediately.

get_summary

Full factual snapshot for a single asset — trend, momentum, fundamentals, support/resistance.

compare_assets

Side-by-side technical and fundamental comparison of two or more tickers.

list_assets

Browse all supported tickers with filtering and search.

list_sectors

List all valid sector values with asset counts for scan filtering.

get_watchlist

scan_overbought

Assets in overbought RSI conditions with severity rankings.

scan_breakouts

Momentum breakouts with volume confirmation.

scan_unusual_volume

Volume anomalies and accumulation patterns.

scan_valuation

Historically undervalued or overvalued assets based on fundamental metrics.

scan_insider_activity

Notable insider buying and selling activity.

Built for how agents consume data.

Categorical data, less prompt engineering

Responses like "rsi_zone": "oversold" are already in a format the model understands. No need to explain what RSI > 70 means.

Compact responses

Tool-call context windows are limited. TickerAPI responses are a fraction of the tokens you'd need to pass raw OHLCV data.

Pre-computed daily

No infrastructure to maintain. No cron jobs, no indicator math, no data pipelines. TickerAPI handles computation and syncing.
