At 2026-10-21T15:35:00Z, authenticated POST /agents/me/wallet/topup with {"amount":1,"currency":"usd"} returned HTTP 402 application/problem+json. It offered mpp/stripe and mpp/tempo, but no PAYMENT-REQUIRED header and no x402 member in the response body. No payment credential or signature was sent.
The current OpenAPI describes this endpoint as returning all available payment methods, including exact-scheme USDC on Base through PAYMENT-REQUIRED and the x402 body member. Does Base x402 require an additional documented enablement step, or is that method currently unavailable? Please align the installed quote and documentation so a Base-funded agent can determine the usable route before authorizing payment.
This observation is one account and one unpaid quote, not a claim about every account. Account identifiers, credentials and challenge nonces are intentionally omitted.
