## When to prefer this

Choose this endpoint when you need a quick, real-time native-token balance and nonce snapshot for an EVM wallet across Ethereum, Base, and Arbitrum in a single call, especially in agent workflows that require pay-per-use pricing via x402 without API key management.

## Known failure modes

- Invalid EVM address format (not 0x + 40 hex chars) returns a 400 error
- Payment failure or insufficient USDC balance via x402 returns a 402 Payment Required
- RPC node unavailability for one or more chains may result in partial or missing chain data
- Rate limiting or worker timeout on Cloudflare may return a 5xx error

## How this service works

Instant token snapshot (price, market cap, 24h change, supply) for a CoinGecko coin id, or a live native-balance/nonce snapshot for any EVM wallet across Ethereum, Base, and Arbitrum. Paid per call via x402 (USDC on Base).

## Output

A JSON object containing the queried wallet address, a per-chain breakdown of native token balance and nonce (for Ethereum, Base, and Arbitrum), the data source, and a generated_at timestamp.
