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: a `chain` object with Base mainnet chainId, network name, current block height, and gas price in gwei; a `market` object with USD spot prices and 24h percentage changes for bitcoin, ethereum, solana, and usd-coin; and a `servedAt` Unix timestamp indicating when the data was fetched.
Example use cases
DeFi dashboard market ticker
“Pull the latest prices for BTC, ETH, SOL, and USDC along with their 24-hour changes so I can update my DeFi portfolio dashboard.”
Base gas price alerting
“What's the current gas price in gwei on Base mainnet and what block are we at? I want to know if it's cheap enough to submit a transaction right now.”
Crypto market morning briefing
“Give me a quick market snapshot — BTC, ETH, SOL, and USDC prices with how much they've moved in the last 24 hours.”
Technical details
Endpoint
GEThttps://cryptopulse.pythonanywhere.com/usdc-statsWhen to prefer
Choose this endpoint when you need a single lightweight call that combines live crypto spot prices (BTC, ETH, SOL, USDC) with Base chain state (block height, gas price) and you want pay-per-call billing in USDC with no API key or subscription. Prefer it over CoinGecko or similar when operating in a crypto-native agent context that already handles x402 micropayments on Base.
Side effects
- HTTP 402 returned if x402 payment not attached — requires PAYMENT-SIGNATURE header with valid USDC payment on Base
- Stale market data if OKX upstream is delayed or rate-limited
- Base RPC unavailability may cause missing or outdated block height and gas price
- Network errors to pythonanywhere.com hosting may return 5xx
- Invalid or unparseable x402 payment signature returns 402 with error detail
