tx_status
[Crypto/Base] Check a Base transaction: success/reverted/pending, confirmations, gas, explorer link. Costs $0.002. Choose this for a quick raw status; use payment_receipt for decoded transfers, or settlement_assurance to PROVE an x402 payment settled to the right wallet/amount.
入力スキーマ
{'type': 'object', 'required': ['hash'], 'properties': {'hash': {'type': 'string', 'pattern': '^0x[0-9a-fA-F]{64}$'}}}

Costs $0.01. Use this to grade an endpoint before trusting/publishing it; use settlement_assurance instead when you already have a transaction hash and want to prove a completed PAYMENT settled correctly.

Examples: 'audit https://api.example.com/paid', 'price of eth', 'is 0x… a contract', 'verify settlement 0x…', 'search the bazaar for weather'. Use this when you don't want to choose among the individual tools below. Costs $0.03 (USDC via x402).
入力スキーマ
{'type': 'object', 'required': ['q'], 'properties': {'q': {'type': 'string', 'description': 'Your goal in plain English'}}}
x402_simulate

Costs $0.003. Use this before paying an unfamiliar endpoint; use x402_inspect to lint an endpoint you own.
入力スキーマ
{'type': 'object', 'required': ['url'], 'properties': {'url': {'type': 'string', 'description': 'The x402 endpoint to pre-flight'}, 'address': {'type': 'string', 'description': 'Optional payer wallet (0x…) for a Base affordability check'}}}
