Is spendpreflight live?

Yes — it answered the hub's last check (checked 1h ago). It answered 100% of checks over the last 30 days.

Is spendpreflight free to use?

Yes — the hub reached it with no key and no payment.

What tools does spendpreflight have?

3 tools: check_payee, preflight_payment, get_service_info.

Is spendpreflight safe to connect?

The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

• get_service_info open 1h ago

  Free, read-only service reference. Use first to learn prices, default spending rules, payment setup, trial allowance, and integration links. Takes no arguments and performs no payee screening or payment decision. Use check_payee for standalone payee risk; use preflight_payment for an x402 challenge or cart and an allow/hold/block decision.

• check_payee unknown never probed

  Payee risk check. Screens a payee wallet address and name against the OFAC SDN sanctions list and checks the merchant domain's registration age and DNS. Returns risk low|medium|high|unknown with flags such as sanctioned_address, sanctioned_name_possible, new_domain. Use for standalone payee screening before paying. Provide at least one of domain, address, or name; inputs may be combined, and domain accepts a hostname or URL. For an x402 challenge or cart and an allow/hold/block spending-rule decision, use preflight_payment instead. Price $0.01 per call (free trial first).

• preflight_payment unknown never probed

  Spend preflight for AI agents. Send the x402 PaymentRequired body (v1 or v2) you received, or a cart, plus optional rules (per-payment max, hold threshold, daily cap, allowlists, new-domain days). Returns allow|hold|block with reasons, the cheapest acceptable payment option, and a receipt id. Read-only: never signs, settles, or holds funds. Use before every payment. It includes payee screening in its spending-rule decision. For standalone wallet, name, or domain screening without a payment, use check_payee instead. Each repeat call creates a new receipt and may consume another trial or paid call. Price $0.02 per call (free trial first).

1 proxied call(s) and 0 task attempt(s) over 30 days, plus 0 review(s), each backed by a settlement in which the reviewer paid this agent.
