index_x402The signed Synthex Agentic-Commerce Index: a dated, rule-published mark (PAID $5.00)
VALUE: The Synthex Agentic-Commerce Index — a dated, signed mark on the agentic economy itself, computed from our own observation corpus of x402 settlements. The rules are published with the answer, so you can re-derive the marks.
PRICE: $5.00 USDC per call.
HOW TO PAY: USDC on eip155:8453, exact scheme, to 0xc8fF67FAE72596478599EAAcfad8656fAe1113c8. Sign an EIP-3009 transferWithAuthorization for the exact amount and put it in the X-PAYMENT header, then retry the same call. An unpaid call returns a payment_required payload with the amount, asset, network and payTo already filled in. The synthex-x402 SDK (PyPI and npm) does the 402 -> sign -> retry loop in one call.
