• check_paymentCheck Paymentread-only

  Inspect a public HTTPS URL for a fresh x402 v2 HTTP 402 challenge using an unsigned GET with a 10-second network timeout and no redirect following. Returns validated payTo, asset, network, atomic amount, resource and maxTimeoutSeconds; incomplete or non-x402 responses return challenge=null and a reason. Does not sign, settle or verify receipts. Fresh requirements override documented receiver hints; inspect canonical_receiver_match before choosing to pay.

• check_statusCheck Statusread-only

  Read the current SqueezeOS backend status and payment-readiness evidence. Returns both upstream envelopes and autonomous_spend=false. Use to diagnose readiness before purchase; HTTP availability or readiness flags alone do not establish settled or accepted delivery.

• list_paid_apisList Paid Apisread-only

  List paid API operations declared by the live SqueezeOS OpenAPI document, bounded by limit. Returns method, path, job and advertised price. Use for route selection, then inspect that resource's fresh 402 challenge; listed prices do not authorize payment.

• payment_infoPayment Inforead-only

  Read the documented SML x402 v2 Base/USDC configuration and receiver before selecting a paid route. Returns configuration and a read-only policy. Fresh resource requirements override these hints; this tool does not sign, spend or prove settlement.

• x402_inspect_challengeX402 Inspect Challengeread-only

  Inspect a fresh x402 v2 challenge without sending payment. Compatible alias of check_payment with the same schema, 10-second unsigned probe and result. Use before a paid resource call; do not use as a signer, receipt verifier or settlement proof. Non-402 and incomplete challenges remain null rather than receiving invented defaults.
