Chart Splat (x402)

by @bobbyg603

Generate beautiful charts by paying per request with x402 micropayments (USDC on Base) instead of an API key. Use when the user wants a chart and has no CHAR...

Versionv1.0.1
#crypto#requires-wallet#can-make-purchases#can-sign-transactions#requires-sensitive-credentials
βš™οΈ Configuration

  • An EVM wallet with β‰₯ $0.05 USDC on Base mainnet (eip155:8453)
  • Private key exported as X402_PRIVATE_KEY (a hex string starting with 0x)
  • Node.js 20+

    • The buyer never submits an on-chain transaction directly. The Coinbase x402 facilitator handles settlement and pays gas. See references/x402-protocol.md for protocol detail.

    πŸ“‹ Tips & Best Practices

  • The CLI accepts the full Chart Splat request body via --config β€” see examples/sample-charts.json for ready-to-use samples or chartsplat.com/docs for the full schema
  • For pie/doughnut charts, pass an array of colors via --config so each segment gets a distinct color
  • Default dimensions (800x600) suit most uses; raise via options.width / options.height for presentations
  • Settlement is logged with a BaseScan URL β€” keep these for accounting
