Guavy 3.0 launch · live July 15

What the world feels, before the markets react.

Sentiment moves first. Price is always the last to know. Guavy scores six dimensions of market mood across every major asset class, delivered to apps, funds, and AI agents over REST and native MCP.

Models are a commodity.
Data is the moat.

Every agent runs on the same handful of frontier models. What separates a sharp agent from a guessing one is the quality and freshness of the data it reasons over. Guavy is that layer, built API-first and MCP-native, so any model in any framework gets the same structured, real-time market context.

Everything an agent needs to reason about a market

The building blocks for trading bots, predictive models, research agents, and market apps, delivered via a single, high-performance API.

Sentiment analysis

Market mood scored across six dimensions: Sentiment, Clout, Speculation, FUD/FOMO, Confidence, and Tone. Structured signal, not a single bullish-or-bearish guess.

Curated news

Get realtime content with enhanced metadata including briefs, summaries, clout, sentiment and relevancy scores.

Trend signals

We combine traditional technical analysis with AI models to detect changes in market trends and conditions.

AI-native integration

Built for AI agents with native MCP and llms.txt support for seamless LLM integration.

Comprehensive coverage

Crypto is live today; forex, commodities, and stocks are next. All on one API and MCP surface, with the same scored sentiment, trend signals, and curated news in every market.

Developer-first design

Simple REST API with clear documentation allows devs to integrate sentiment, content, and signals in minutes.

What builders are creating

From solo developers to institutional quant teams, here's how Guavy's API powers real agentic workflows.

01 / Sentiment Monitor

Sentiment-triggered alert agent

An agent that polls sentiment history across a portfolio of assets and fires alerts or webhooks when sentiment crosses defined thresholds. No manual monitoring required.

02 / Trading Bot

Signal-driven autonomous trader

Feed Guavy's buy/sell/hold signals and backtest data into an LLM-powered trading agent. Let it reason about when to enter and exit positions using AI-validated trend data.

03 / Research Agent

Daily market intelligence brief

An agent that pulls the AI market summary, top movers, and instrument-specific analysis each morning and composes a concise brief delivered to Slack, email, or a dashboard.

04 / RAG / Knowledge Base

Market-aware LLM with live context

Inject live Guavy news briefs into your RAG pipeline so your LLM answers questions with up-to-the-minute market context, not stale training data.

05 / Mobile / App

AI-powered market data app backend

Build a mobile or web app that surfaces personalized asset recommendations, sentiment charts, and curated news, all powered by a single Guavy API key.

06 / Institutional

Quant fund data feed

Augment quantitative models with AI-generated sentiment and signal data across every asset you track. Backtest against 5+ years of historical trend data with structured JSON responses.

    Connect via MCP (optional)

    For native agent tool-use, use Guavy's MCP server to give your agent first-class access to sentiment, signals, and news as callable tools.

python
# Get live Bitcoin sentiment for your agent
import requests

API_KEY = "YOUR_GUAVY_API_KEY"
BASE = "https://guavy.com/api/v1"

headers = {
  "Authorization": f"Bearer {API_KEY}"
}

# Fetch today's BTC sentiment
r = requests.get(
  f"{BASE}/sentiment/get-sentiment-history/btc",
  headers=headers,
  params={"limit": 1}
)

today = r.json()["sentiment"][0]
print(f"BTC positive: {today['positive']}")
print(f"BTC negative: {today['negative']}")

# Get trade signal
signal = requests.get(
  f"{BASE}/trades/get-current-action/btc/aggressive",
  headers=headers
).json()

print(f"Signal: {signal['action']}")
# → Signal: Buy

Works everywhere you build

What you gain

Concrete advantages for builders who add Guavy to their stack.

< 5 min

Time to your first signal

Plain REST with Bearer auth. No SDKs, no setup. Your agent is calling live market data before the coffee is done.

5+ yrs

Of backtest history

Validate strategies against years of sentiment, trend, and signal data, not just the last 30 days. Know what holds before you ship.

1 key

Every market, one API

Crypto is live today; forex, commodities, and stocks are next. The same endpoints and MCP tools across markets, so it's one integration with no re-architecting as coverage grows.

0 lag

React before the chart moves

Sentiment and signals update continuously throughout the day, so your agent acts on market shifts before they show up in price.

Don't build the data layer. Build on it.

Reproducing real-time market sentiment in-house means standing up scrapers, scoring models, news enrichment, and backtest infrastructure, then maintaining all of it forever, in every market. Guavy is that entire layer behind one API key.

Build it in-house

Your roadmap
  • Stand up and babysit scrapers and data pipelines across dozens of sources.
  • Train, tune, and continuously re-validate sentiment models across six dimensions.
  • Enrich and score news in real time for clout, relevance, and tone.
  • Warehouse years of history and build backtest infrastructure from scratch.
  • Rebuild the whole stack again for every new market you add.
  • Own the uptime, on-call, and maintenance indefinitely.

Build on Guavy

Your product
  • One API key and structured JSON, live in minutes.

Start free. Scale as you build.

Sandbox is free forever. No credit card. Quant for builders, Pro for power users.

Common questions

Which markets does Guavy cover?
Crypto is live today; forex, commodities, and stocks are next. Every live market carries full sentiment, news, and signal data scored across six dimensions, on the same API and MCP surface, so anything you build on one market's endpoints extends to the rest without re-architecting.
How do I connect Guavy to Claude or another LLM?
The easiest way is to provide Claude (or any LLM) with the URL https://guavy.com/llms.txt. This file contains the complete API spec in a format LLMs understand natively. Your agent will know every endpoint, parameter, and response format without any additional setup. For MCP-native integration, use the Guavy MCP server so your agent can call market data as first-class tools.
Does Guavy support the Model Context Protocol (MCP)?
Yes. Guavy has native MCP server support, making it one of very few market data APIs that integrates directly with agentic frameworks that use MCP. This means your agent can discover and call Guavy endpoints as tools without writing any glue code or custom function definitions.
What does "real-time" mean, and how fresh is the data?
Sentiment scores, news briefs, and trade signals are updated continuously throughout the day. Price and market cap data reflects current market conditions. The get-market-summary and get-instrument-analysis endpoints are refreshed daily with AI-generated summaries of current conditions.
Can I use Guavy data in a commercial product or SaaS app?
The self-serve plans (Sandbox, Quant, and Pro) are licensed for personal use. Commercial use in apps, funds, or agents, plus white-label data and redistribution, is covered by an Enterprise license priced to your assets under management. Talk to our sales team to scope it.
Is there a rate limit I need to worry about?
The API has a limit of 10 simultaneous connections. Monthly token budgets depend on your plan: 3,000 for Sandbox, 250,000 for Quant, and 1,000,000 for Pro. Different routes consume different token amounts based on data depth. For large data syncs, use pagination parameters (limit and skip) to batch requests efficiently.
