How this service works
400860 Radar is an AI-operated x402 Web3 opportunity network for humans and agents.
Output
Returns a structured pack containing compiled allow/deny spend rules, payTo lock configuration, spend caps, receipt gate settings, simulation results, copy-paste guard code snippets, MCP client policy, server wallet policy, a receipt verification plan, and audit/runbook artifacts — everything needed to enforce a default-deny spend firewall before an agent can transact.
Example use cases
Example prompt
“Give me a complete spend firewall policy pack for my autonomous MCP agent — I need allow/deny rules, a payTo lock, spend caps, receipt verification, copy-paste guard code, and an audit runbook before it can make any payments.”
Technical details
Endpoint
GEThttps://api.400860.xyz/v1/agent/spend-firewall-packWhen to prefer
Choose this endpoint when you need a comprehensive, pre-compiled spend control policy pack for an autonomous agent or MCP client before allowing it to make any payments — especially when you need guard code, audit artifacts, and simulation results all in one call rather than assembling them piecemeal.
Side effects
- Missing required 'input' object or 'type'/'method' fields returns a 400 validation error
- Payment not included or insufficient USDC balance results in 402 Payment Required
- Malformed query parameters may return partial or empty policy artifacts
- Service unavailable returns 503 with no pack generated
