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
Returns a JSON object with: current ETH price in USD and standard gas in gwei; total DeFi TVL in USD; global BTC dominance percentage and total crypto market cap; an array of top coins with symbol, price, and 24h percentage change; a fear & greed index value and label (e.g. 'Greed'); and total stablecoin market cap.
Example use cases
Morning crypto market briefing
“Pull up the latest crypto market pulse for me — I want to see Bitcoin's price, total market cap, fear and greed index, and whether gas fees are reasonable right now.”
DeFi TVL and stablecoin monitoring
“What's the current total value locked in DeFi and how big is the stablecoin market right now? I'm trying to gauge overall liquidity in the ecosystem.”
Bitcoin dominance tracking
“What's Bitcoin's dominance percentage in the crypto market today, and what's BTC's 24-hour price change? I want to know if alts are gaining or losing ground.”
Technical details
Endpoint
GEThttps://three.ws/api/x402/market-pulse?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a single aggregated crypto market snapshot covering multiple metrics (price, dominance, DeFi, gas, sentiment) in one call rather than querying multiple specialized APIs. Useful for dashboards, agents needing market context, or briefings where breadth matters more than deep per-asset data. The micropayment model ($0.005 USDC) makes it cost-effective for frequent polling.
Side effects
- Payment not received or insufficient USDC — returns 402 Payment Required
- Upstream data provider unavailable — may return 503 or stale/empty data
- Malformed request — returns 400 Bad Request
- Rate limiting if payment is disputed — returns 429
