https://x402-agent-hub.x402-agent-hub.workers.dev/v1/chain/portfolioOverview
One call returns an address's native coin, USDC and USDT balances on Base, Ethereum, Arbitrum, Optimism, Polygon, BSC and Avalanche (or a 'chains' subset), plus a total stablecoin USD figure, instead of 21 separate reads. Chains whose RPC fails are listed in chainsFailed. You only pay for successful reads: invalid input, not-found and upstream errors cancel settlement.
