How this service works
Pay-per-call API for AI agents, settled in USDC on Base mainnet (eip155:8453) via the x402 protocol - no API keys, no signup, no subscription. Live crypto market data: BTC, ETH, SOL, USDC (USD Coin) prices with 24h change (source: OKX), Base mainnet chain snapshot (block height, gas price gwei), real-time USDC-on-Base transfer analytics (transfer count, volume, unique senders and recipients over recent blocks), and USDC/ETH wallet balances plus nonce for any address. Agent utility tools: deterministic JSON repair for LLM output (strip code fences, fix trailing commas, single quotes, unquoted keys, balance braces), DNS A/AAAA lookup, and URL extraction from arbitrary text. Every endpoint returns HTTP 402 with an x402 payment challenge in USDC on Base; pay with any wallet and retry with the PAYMENT-SIGNATURE header. MCP server at /mcp (streamable HTTP, 6 pay-per-call tools). Ideal for crypto portfolios, DeFi dashboards, market analysis agents, data pipelines, and LLM post-processing.
Output
A JSON object containing: chain info (chainId, network name, block height, gas price in gwei), market prices and 24h percent change for bitcoin, ethereum, solana, and usd-coin (sourced from OKX), and a servedAt Unix timestamp.
Example use cases
Live crypto dashboard data feed
“Pull the latest BTC, ETH, SOL, and USDC prices along with their 24-hour changes, and also grab the current Base mainnet block height and gas price so I can update my DeFi dashboard.”
Gas price check before on-chain transaction
“Before I send this transaction on Base, what's the current gas price in gwei and the latest block height on Base mainnet?”
Crypto portfolio morning briefing
“Give me a quick market pulse — current prices and overnight 24h changes for Bitcoin, Ethereum, and Solana, plus the Base network status right now.”
Technical details
Endpoint
GEThttps://baseusdcearn.pythonanywhere.com/util/timeWhen to prefer
Choose this endpoint when you need a single low-cost pay-per-call snapshot combining crypto market prices and Base chain stats without API keys or subscriptions — ideal for agents that need occasional price checks or chain status rather than a high-frequency streaming feed. Prefer over subscription APIs when you want keyless, micropayment-based access settled in USDC on Base.
Side effects
- HTTP 402 returned if x402 USDC payment on Base not provided or signature invalid
- stale market data if OKX feed is delayed
- Base RPC timeout causing missing chain fields
- malformed payment header results in payment rejection
