# GlobalStake Agentic

> The staking data layer for agents. Ethereum validator, reward and execution data from GlobalStake, paid per request in USDC on Base via x402. No signup, no API key.

Payment flow: POST to a route. A paid route returns 402 with a base64 PAYMENT-REQUIRED header (amount, asset, network, payTo). Sign an EIP-3009 USDC authorization on Base (eip155:8453) and resend the same request with PAYMENT-SIGNATURE. A settled request returns 200, the JSON body and a PAYMENT-RESPONSE receipt. A rejected payment returns a fresh 402. 503 X402_SETTLEMENT_UNCERTAIN means retry later without signing again. A GlobalStake Bearer token skips payment.

Every request body takes "chain": "MainnetEth". Responses follow the beaconcha.in v1 API format.
