Operated by SpendPreflight. Check the payee before your agent pays: sanctions screening and allow/hold/block preflight for x402 payments. Production Streamable HTTP endpoint: https://api.spendpreflight.com/mcp Production tools: check_payee ($0.01 USDC), preflight_payment ($0.02 USDC), check_endpoint ($0.005 USDC for fresh publicly indexed data), and get_service_info (free). Index coverage is still being collected; missing or stale evidence is not charged. Scout staging preview: find_endpoint ($0.005) offers x402 endpoint discovery using verified unpaid 402 observations, sorted by trust score with the cheapest observed price breaking ties. verify_endpoint ($0.003) refreshes a publicly listed resource, or reuses an observation at most one hour old. Use preflight_payment before paying. Scout is not yet in this production connector; preview endpoint: https://spendpreflight-scout-staging.payee-check.workers.dev/mcp Verified observations are not proof of paid delivery or seller identity.
