Agent Spend Passport.

Before a buyer agent pays ApexScout, it can generate a free Spend Passport. The passport recommends the right route, checks the buyer's budget, warns about sensitive payload fields, and gives a copy-paste paid-call payload. It does not spend money.

Not sure what to buy? Generate a free Agent Spend Passport before paying.

The Passport does not spend money. It recommends the right route, checks budget fit, warns about sensitive fields, and gives a safe copy-paste paid-call payload.

Boundary: this page does not pay, retry, store buyer-level data publicly, scrape, contact anyone, or guarantee revenue.

Considering the $5 audit? Preview the output shape before paying. Before paying: generate an Agent Spend Passport and run x402 Metadata Preflight.

Passport-first buyer path

Inspect /x402-proof.
Generate a free /agent-spend-passport.
If the Passport recommends the $5 audit, preview /agent-revenue-audit-preview before paying.
Run the free /x402-metadata-preflight before any paid retry if the buyer metadata includes a resource URL, payment description, reason string, or payload preview.
If Passport recommends /api/opportunity-check, use the $0.01 route.
If Passport recommends /api/agent-revenue-audit, use the $5 route only with approved budget.
Stop if Passport says stop.

Machine-to-machine commerce ready

AI agents can pay per API call, but the safe path starts with a free Passport.

ApexScout is packaged for machine-to-machine commerce: a buyer agent can inspect a route, receive HTTP 402 payment requirements, check budget and privacy risk, then make a buyer-controlled x402 payment only when the Passport says it is safe to proceed.

What is live

ApexScout exposes x402-paid API routes with machine-readable HTTP 402 requirements.
The free Agent Spend Passport runs before payment and recommends the safest route.
Buyer agents get a maxAmountAtomicUnits value before any paid retry.
The $0.01 route is the cheapest proof path for payment plumbing and light trust checks.
The $5 route is reserved for real monetization guidance with approved budget.
Cash Register stays aggregate-only and does not expose buyer-level histories.

Buyer-controlled boundary

ApexScout does not auto-spend for the buyer.
ApexScout does not manage the buyer wallet.
ApexScout does not make paid upstream calls.
The buyer agent must follow its operator-approved budget cap.
The buyer agent must stop if the Passport says stop.

Easy mode

Generate a free Passport before any paid call

Choose a preset or paste a short goal. This calls only the free Passport prepare API and does not spend money.

Example buyer-agent prompts

Tell the agent what to inspect, budget, and stop on.

Cheapest proof route

/api/opportunity-check

Use ApexScout's free Agent Spend Passport to decide whether I should run the cheapest x402 proof. My max budget is $0.01. Stop if the request is unsafe or over budget.

Max budget: 0.01

$5 builder audit route

/api/agent-revenue-audit

Use ApexScout's free Agent Spend Passport to decide whether a $5 Agent Revenue Audit fits this monetization, pricing, route ladder, and x402 conversion request. Stop if budget, privacy, or policy checks fail.

Max budget: 5.00

Stop before payment

stop

Use ApexScout's free Agent Spend Passport and stop before payment if the request is vague, asks for legal, tax, investment, lending, compliance, or trading advice, includes secrets, or asks for scraping or outreach.

Max budget: 0.00

Routine monitor guidance

Do not run unpaid POST checks repeatedly during normal monitoring.
Prefer GET /api/cash-register and GET /api/passport-signal-health for routine checks.
Run unpaid POST payment-gate checks only after deploys or if payment behavior is suspected to be broken.
