How this service works
Make a 3D AI agent from a selfie in 60 seconds. Drop one HTML tag to embed it on any website. Agents think on IBM watsonx.ai (Granite); optionally charge per chat with built-in micropayments.
Output
A JSON object containing a 'market' object (BTC dominance as a percentage, total market cap in USD, 24h trading volume in USD) and a 'fear_greed' object (numeric value 0–100 and a human-readable label such as 'Greed', 'Fear', 'Extreme Greed', etc.).
Example use cases
Morning crypto market briefing
“Before I check the markets today, give me a snapshot of the total crypto market cap, Bitcoin dominance, and whether sentiment is fearful or greedy right now.”
Crypto dashboard data refresh
“Pull the latest global crypto market data for my dashboard — I need total market cap, 24h volume, BTC dominance percentage, and the Fear & Greed score.”
Crypto trading context check
“Before I make a trade, what does the overall crypto market look like? Give me BTC dominance, total market cap, and the current Fear & Greed reading.”
Technical details
Endpoint
GEThttps://three.ws/api/x402/market-global?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a high-level global crypto market snapshot — total cap, volume, BTC dominance, and sentiment — in a single low-cost call ($0.001 USDC). Prefer it over exchange-specific APIs when you want aggregated market-wide data rather than per-coin or per-exchange figures. It is especially useful for dashboards, morning briefings, and pre-trade context checks where a quick macro read suffices.
Side effects
- Payment not received (402): call requires $0.001 USDC via x402 payment; missing or invalid payment header returns 402
- Invalid properties filter: malformed query parameter may return empty or error response
- Upstream data unavailable: if the underlying market data provider is down, response may be stale or missing
- Rate limiting: excessive calls without payment may be throttled
