How this service works

AI agent spending policy via x402 v2 micropayments on Base Mainnet.

Output

Returns a JSON object with: allowed (boolean indicating if the action is within policy), reason (plain-text explanation), calls_today (integer count of calls made today), trust_score (float 0–1 indicating agent trustworthiness), daily_spent_usd (amount spent today), and daily_budget_usd (the configured daily cap).

Example use cases

Example prompt

“Before you make that $0.001 USDC payment, check whether I'm still within my spending policy — my daily budget is $10 and I want to know my current trust score and how many calls I've made today.”

Endpoint

When to prefer

Use this endpoint when an AI agent needs to self-govern its spending behavior before executing x402 micropayments on Base Mainnet — especially when enforcing daily budget caps, tracking cumulative spend, or evaluating whether an autonomous agent's trust score meets policy thresholds. Prefer this over generic rate-limiters when the context is USDC micropayments and you need both a binary allow/deny decision and rich telemetry (trust score, daily spend).

Side effects

Payment not included or invalid x402 payment header — returns 402 Payment Required
Daily budget exceeded — returns allowed: false with reason explaining limit reached
Trust score too low — returns allowed: false with reason indicating insufficient trust
Malformed request body — returns 400 Bad Request
Network or Vercel cold-start timeout — returns 5xx error
