How this service works
Pay-per-call stock, macro, on-chain, and crypto data over the x402 protocol. USDC on Base or Solana, no API keys, no subscriptions.
Output
A JSON object containing: as_of (ISO 8601 timestamp), total_market_cap_usd (global crypto market cap in USD), total_volume_24h_usd (24-hour trading volume in USD), dominance_pct object with BTC/ETH/USDT percentage shares, active_cryptocurrencies (count of active coins), markets (number of markets tracked), and market_cap_change_pct_24h (percentage change in market cap over the last 24 hours).
Example use cases
Morning crypto market briefing
“Pull me a quick snapshot of the overall crypto market right now — total market cap, 24h volume, and Bitcoin's dominance percentage so I can start my morning briefing.”
Portfolio rebalancing market check
“Before I rebalance my portfolio, can you check the current global crypto market cap, BTC dominance, and whether the market is up or down in the last 24 hours?”
Automated market alert monitoring
“Every hour, fetch the current total crypto market cap and BTC dominance and alert me if the market cap drops more than 2% compared to the last reading.”

Endpoint
GEThttps://x402financialdata.com/crypto-market-overviewWhen to prefer
Choose this endpoint when you need a fast, no-subscription, pay-per-call global crypto market overview without managing API keys. It is ideal for agents that need occasional or infrequent market snapshots (cost-efficient at $0.005/call), and for workflows that operate on Base or Solana USDC. Prefer this over subscription-based data APIs when call volume is low or unpredictable.
Side effects
- Payment not included or insufficient USDC — returns HTTP 402 Payment Required
- Network/USDC payment settlement failure — call must be retried with valid x402 payment header
- Upstream data provider unavailable — may return 503 or stale/empty data
- Malformed request — returns 400 if required headers are missing
