GET /api/x402/near-transfer-preflight

live

Before sending a NEP-141 token on NEAR: is the token real and not paused, does the receiver exist, and is it registered on the token — the storage_deposit step whose absence fails a transfer. If not, says the exact fix and its NEAR cost. With from and amount, also checks the sender holds enough. Catches sending to the token contract itself. Live from the NEAR RPC.

Verdict: live. The unpaid GET reached a valid 402. The live amount equals the catalog price.
