Fetch a URL, automatically paying if it requires payment (HTTP 402, x402 protocol) — within the operator's spending policy. Free URLs are fetched normally at no cost. Use payment_quote first if you only want to know the price. Payments above the operator's approval threshold will ask the human for confirmation. Spending policy is operator-owned config; no tool can widen it.

Check what a paid URL costs and whether the current spending policy would allow paying it, WITHOUT paying. Returns the price, payment terms, trust-check results, and the policy decision. Spending policy is operator-owned config; no tool can widen it.

Show today's agent spending: totals, remaining budgets overall and per host, active holds, and recent payments. Spending policy is operator-owned config; no tool can widen it.

Query the local payment receipt ledger (audit trail). Filter by time, host, or outcome. Spending policy is operator-owned config; no tool can widen it.

List or resolve payments waiting for human approval (queue mode). Approving grants a one-time re-run permission for that exact payment. It only resolves payments already queued for approval; it cannot change spending policy — no payfetch tool can widen operator-owned limits.
