How this service works
Public data and utility APIs paid per call in USDC on Base (x402). No accounts, no API keys. 174 routes: crypto/equity data, onchain reads, DNS/email/security intel, geo/weather, x402 payment diagnostics, dev utilities and more.
Output
A JSON object containing: btc_dominance_pct (Bitcoin's share of total crypto market cap as a percentage, e.g. 54.2), total_market_cap_usd (total crypto market capitalization in USD, e.g. 2.4 trillion), and active_cryptocurrencies (count of actively traded cryptocurrencies, e.g. 22501).
Example use cases

Technical details
Endpoint
GEThttps://anibalb.duckdns.org/x402/global-market?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, no-account, no-API-key global crypto market summary paid per-call in USDC via x402 on Base. Ideal for agents that need lightweight macro crypto context (BTC dominance, total market cap, active coin count) without subscribing to a full market data plan. Not suitable if you need per-coin prices, historical data, or granular altcoin breakdowns.
Side effects
- Payment failure if USDC balance insufficient on Base network
- Upstream data provider unavailable — may return 503 or stale data
- Rate limiting if too many calls in short succession
- DuckDNS dynamic hostname may occasionally resolve incorrectly
