Credentials Issue
credentials_issueRead-onlyIdempotent
Issue a scoped, expiring, offline-verifiable capability credential (PAID $0.05)
VALUE: A scoped, time-limited, signed credential — delegation with an expiry, so access does not have to be revoked by hand.
PRICE: $0.05 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.
