Live sentiment scores, curated news, and AI-driven trading signals delivered via a clean REST API built for the agentic era. Works with Claude, ChatGPT, Gemini, Grok and any LLM out of the box.
// The problem
Standard crypto APIs were designed for humans building dashboards. Agents need something different — structured, semantic, and signal-rich.
Knowing BTC is $67,000 tells your agent nothing. Is that bullish or bearish? Is sentiment rising or falling? Price alone is noise.
Scraping news for an agent means parsing HTML, deduplicating sources, and scoring relevance yourself. It's weeks of work before you even start building.
Most crypto APIs have no MCP server, no llms.txt, and no concept of agent-to-API communication. You're on your own writing glue code.
Sentiment scores, AI-curated news with metadata, trend signals, and native MCP + llms.txt support. One API. Your agent is live in minutes.
// Use cases
From solo developers to institutional quant teams — here's how Guavy's API powers real agentic workflows.
An agent that polls sentiment history across a portfolio of coins and fires alerts or webhooks when sentiment crosses defined thresholds. No manual monitoring required.
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.
An agent that pulls the AI market summary, top movers, and coin-specific analysis each morning and composes a concise brief delivered to Slack, email, or a dashboard.
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.
Build a mobile or web app that surfaces personalized coin recommendations, sentiment charts, and curated news — all powered by a single Guavy API key.
Augment quantitative models with AI-generated sentiment and signal data for 350+ coins. Backtest against 5 years of historical trend data with structured JSON responses.
// Quickstart
No SDKs to install. Standard REST with Bearer token auth. Works with any HTTP client.
Sign up at data.guavy.com. No credit card needed for the Sandbox tier. Your key is ready instantly.
Paste https://data.guavy.com/llms.txt
into Claude, GPT, or any LLM. It contains the full API spec — your agent knows exactly what to call and how.
Standard GET endpoints. JSON responses. Add your Bearer token to the Authorization header and you're calling live crypto data in seconds.
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.
# Get live Bitcoin sentiment for your agent import requests API_KEY = "YOUR_GUAVY_API_KEY" BASE = "https://data.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
// Integrations
Native llms.txt support means any LLM can understand and call the Guavy API without custom instructions.
// For AI agents
No prompt engineering. No custom function definitions. No glue code. Just point your agent at one URL.
The complete Guavy API specification — every endpoint, parameter, and response field — formatted for direct LLM consumption. Point your agent at this URL and it will understand exactly what to call and how, with no additional setup required.
https://data.guavy.com/llms.txt
as a document or paste the URL — Claude will read the spec and write correct API calls immediately.
For agents that use tool-calling natively, Guavy's MCP server exposes sentiment, signals, and news as first-class callable tools — no REST wrappers needed.
