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 with a 'market' key containing BTC, ETH, SOL, and USDC prices in USD with 24h percentage change (sourced from OKX), a 'chain' key with Base mainnet chain ID, block height, and gas price in gwei, and a 'servedAt' Unix timestamp indicating when the data was fetched.
Example use cases
Crypto portfolio morning briefing
“Give me a quick market snapshot — what are BTC, ETH, SOL, and USDC trading at right now, and how much have they moved in the last 24 hours?”
DeFi dashboard gas monitoring
“What's the current gas price on Base mainnet and what block are we on? I need this for my DeFi dashboard to estimate transaction costs.”
Automated market alert agent
“Check the current price of Ethereum and its 24-hour change — if it's moved more than 5% either way, I want to know immediately.”
Technical details
Endpoint
GEThttps://cryptopulse.pythonanywhere.com/crypto/pricesWhen to prefer
Choose this endpoint when you need a single low-cost call that bundles live crypto market prices (BTC, ETH, SOL, USDC) with Base mainnet chain state (block height, gas price) in one response. Ideal for agents that need no API key setup and can pay per-call in USDC on Base via x402. Prefer this over CoinGecko or similar REST APIs when you want pay-as-you-go pricing without subscription overhead, or when you specifically need Base network chain data alongside market prices.
Side effects
- HTTP 402 returned if x402 payment header is missing or invalid — agent must pay 0.001 USDC on Base and retry with PAYMENT-SIGNATURE header
- OKX data may be momentarily stale during exchange downtime
- Base RPC node may return slightly lagged block height during high network load
- Malformed payment signature results in continued 402 rejection
