Familiar market-data calls. A real API where it counts.

gfin gives teams and agents a hosted API surface with native SDK clients, shared caching, and predictable public limits.

Area gfin Local fetch stack
Best fit Apps, services, agents, jobs, dashboards Local notebooks and scripts
Public REST API Hosted API with stable URLs No hosted REST API
Free public limits 20 req/s anonymous, 500 req/s with API key No managed API tier
SDKs Python + TypeScript/JavaScript Application-owned clients
AI and tool use OpenAPI, docs, stable HTTP routes Requires Python execution or a custom wrapper
Integration Use gfin.Client or REST directly Application-owned adapters

One market-data surface, three entry points.

Use the SDK when it fits. Use REST when you want the same data from another language, service, or agent. 

import gfin

client = gfin.Client(api_key="gfin_live_...")
print(client.quotes.get("AAPL", exchange="NASDAQ"))
print(client.prices.history("AAPL", exchange="NASDAQ"))
import { Client } from "@bluefin-ai/gfin";

const gfin = new Client({ apiKey: "gfin_live_..." });
const quote = await gfin.quotes.get("AAPL", { exchange: "NASDAQ" });
console.log(quote.data);

No signup. Install gfin and go.

Start free, verify an email when your app needs more room, and request custom RPS when your workload grows.
