How this service works
Pay-per-call crypto market and Base wallet summaries via x402 (USDC on Base).
Output
A JSON object containing an array of market entries (each with symbol, current USD price, 24h low, 24h high, 24h volume, and 24h change percentage), the active network identifier ('base'), the current Base gas price in gwei, and a UTC timestamp for the snapshot.
Example use cases
Live BTC price check
“What's the current Bitcoin price, its 24-hour high and low, and how much has it changed percentage-wise today?”
Base gas price monitoring
“What is the current gas price on the Base network in gwei? I want to know before I submit a transaction.”
Portfolio snapshot refresh
“Pull me a fresh crypto market summary so I can see today's prices, 24h volumes, and price changes for the major assets before I decide whether to rebalance.”
Technical details
Endpoint
GEThttps://ralph-crypto-summary.simgokr.workers.dev/api/market-summary?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, on-demand crypto market price snapshot with Base network gas data in a micropayment (x402/USDC) context, especially in automated agent pipelines where per-call billing without API key management is preferred. It is ideal for Base-ecosystem DeFi agents that already handle x402 payments natively and need live price feeds without a subscription.
Side effects
- Payment not included or insufficient — returns HTTP 402 requiring x402 USDC payment on Base
- Payment verification failure — x402 facilitator cannot confirm the on-chain payment
- Network/worker unavailability — Cloudflare Worker returns 5xx error
- Market data feed outage — response may return stale or missing price data
- Malformed request — unexpected query parameters may be ignored or cause errors
