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: market prices (BTC, ETH, SOL, USDC in USD with 24h % change sourced from OKX), Base mainnet chain data (chain ID, network name, block height, gas price in gwei), USDC-on-Base transfer analytics (transfer count, volume, unique senders/recipients over recent blocks), optional wallet USDC/ETH balances and nonce, and a servedAt Unix timestamp.
Example use cases
Live crypto portfolio snapshot
“Pull me the latest BTC, ETH, and SOL prices along with their 24-hour percentage changes so I can update my portfolio dashboard.”
Base network gas tracker
“What's the current block height and gas price in gwei on Base mainnet? I need it for my DeFi transaction cost estimator.”
USDC on-chain activity monitor
“How much USDC has been transferred on Base in the last few blocks, and how many unique wallets were sending and receiving? I'm tracking stablecoin activity trends.”
Technical details
Endpoint
GEThttps://cryptopulse.pythonanywhere.com/pulseWhen to prefer
Choose this endpoint when you need a no-signup, no-API-key, pay-per-call crypto data snapshot that combines market prices, Base chain status, and USDC on-chain analytics in a single call — especially for AI agent workflows that already support x402 micropayments on Base. Prefer over subscription-based data providers when you want sub-cent per-call pricing with on-chain settlement and no credential management.
Side effects
- HTTP 402 returned if x402 payment challenge not satisfied — agent must pay in USDC on Base and retry with PAYMENT-SIGNATURE header
- OKX market data unavailable causing partial or stale price response
- Base RPC timeout causing missing chain snapshot fields
- Malformed wallet address returns error or null balance fields
- Rate limits or PythonAnywhere hosting downtime causing 503
