Context
The x402 page doesn't state that the signed
PAYMENT-SIGNATUREcan be reused across calls. A reader following the direct-API steps may assume each call needs a fresh signature and a new on-chain settlement.Solution
:::notein the direct-API section: the samePAYMENT-SIGNATUREstays valid while the prepaid balance lasts; resend it on every call with no re-signing or new settlement, and only sign again when the API returns402(balance exhausted) — the manual equivalent of whatmcpcdoes automatically on the MCP path.
