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.","url":"https://baseusdcearn.pythonanywhere.com/crypto/price/%7Bsymbol%7D","method":"GET","headers":{},"bodySchema":{"type":"object","properties":{"properties":{"type":"string"}}},"responseSchema":{"type":"json","example":{"chain":{"chainId":8453,"network":"base-mainnet","blockHeight":21000000,"gasPriceGwei":0.05},"market":{"solana":{"usd":150,"usd_24h_change":-0.5},"bitcoin":{"usd":60000,"usd_24h_change":1.5},"ethereum":{"usd":3000,"usd_24h_change":2},"usd-coin":{"usd":1,"usd_24h_change":0}},"servedAt":1755430000}},"example":null,"exampleRequest":null,"tags":["x402"],"displayCostAmount":"0.001","displayCostAsset":"USDC","priceDynamic":false,"priceHint":null,"priceStatus":"priced","priceSource":"probe","requiresHandshake":false,"reviewCount":0,"rating":{"score":"0.00","successRate":"0.00","reviews":0,"stars":null,"state":"unrated"},"availabilityStatus":"unknown","priceObserved":null,"sessionDeposit":null,"pricing":{"kind":"static","summary":"$0.001/call","primary":{"kind":"static","protocol":"x402","network":"base","amountUsd":"0.001","per":"call","confidence":"exact"},"accepted":[{"kind":"static","protocol":"x402","network":"base","amountUsd":"0.001","per":"call","confidence":"exact"}]},"paymentMethods":[{"uid":"pm_q1pIlusBkXRp0DwQqKj76","protocol":"x402","methodType":"crypto","chain":"base","mode":"charge","costAmount":"0.001","costPer":"request","priority":0,"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","unit":"request","depositMicros":null,"planRef":null}],"brandName":null,"brandSlug":null,"brandBaseUrl":null,"brandDocsUrl":null,"whatItDoes":"Returns live cryptocurrency price and 24-hour change for a given symbol (BTC, ETH, SOL, USDC), alongside Base mainnet chain stats, paid per-call in USDC via x402.","exampleAgentPrompt":"What's the current price of Bitcoin and its 24-hour change, along with the latest Base mainnet gas price and block height?","exampleUseCases":[{"title":"Live crypto portfolio dashboard","prompt":"Pull the current prices and 24-hour changes for BTC, ETH, and SOL so I can update my portfolio tracker."},{"title":"DeFi gas cost planning","prompt":"What's the current gas price on Base mainnet right now?
