// fastapi

Market data for
FastAPI apps.

TickerAPI Python SDK + FastAPI. Pre-computed market data in your API endpoints, no infrastructure.

try for free read the docs
// setup

Install the SDK.

One dependency. No MCP server, no WebSocket connections — just a Python package that calls the TickerAPI HTTP API.

terminal 
$ pip install tickerapi
// code example

Two endpoints, five minutes.

Initialize the client once, call methods from your route handlers. Every method returns a dictionary ready for JSONResponse.

python 
from fastapi import FastAPI
from tickerapi import TickerAPI

app = FastAPI()
client = TickerAPI("tapi_your_api_key")

@app.get("/summary/{ticker}")
async def get_summary(ticker: str):
    return client.summary(ticker)

@app.get("/scan/oversold")
async def scan_oversold(sector: str = None):
    return client.scan.oversold(sector=sector)
// state changes

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.

python 
@app.get("/watchlist/changes")
async def watchlist_changes():
    changes = client.watchlist.changes(
        tickers=["AAPL", "MSFT", "GOOGL"]
    )
    # each change includes from/to state transitions
    # e.g. trend: "uptrend" → "downtrend"
    return changes
json 
{
  "ticker": "AAPL",
  "changes": [
    {
      "field": "rsi_zone",
      "from": "neutral",
      "to": "oversold"
    },
    {
      "field": "trend",
      "from": "uptrend",
      "to": "downtrend"
    }
  ]
}
// ai integration

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.

python 
import anthropic
from tickerapi import TickerAPI

client = TickerAPI("tapi_your_api_key")
ai = anthropic.Anthropic()

@app.get("/briefing/{ticker}")
async def get_briefing(ticker: str):
    summary = client.summary(ticker)

    message = ai.messages.create(
        model="claude-sonnet-4-20250514",
        max_tokens=1024,
        messages=[{
            "role": "user",
            "content": f"Analyze this market data for {ticker} and provide a brief:\n{summary}"
        }]
    )

    return {"analysis": message.content}
// available methods

// what your agent sees

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"
  }
}
// why tickerapi + fastapi

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.
