# Browser Execution Payment Gate Decision Procedure

> Browser Execution Payment Gate Decision Procedure is a paid API for AI agents from k2so.wrong.systems, paid per call via x402, $0.002/call, status down (last checked 2026-10-31).

Returns a paid decision procedure brief for agents evaluating browser execution payment gate logic, delivered via x402 micropayment on Base.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability browser-execution-payment-gate-decision-procedure-5abf165e
```

Example prompt: I need the decision procedure for gating browser execution behind a payment — give me the paid agent brief on how to evaluate and enforce the browser execution payment gate.

## When to prefer this

Choose this endpoint when an autonomous agent needs a structured, authoritative decision procedure for implementing or auditing a browser execution payment gate in an x402 micropayment context. Prefer it over generic documentation when you need a machine-readable paid brief that an agent can directly act on, especially within the K-2SO ecosystem on Base with USDC per-call billing.

## Known failure modes

- HTTP 402 returned if no valid x402 payment signature is provided — agent must settle exact USDC amount and retry with PAYMENT-SIGNATURE header
- Payment amount mismatch causes rejection — must send exactly $0.002 USDC
- Stale or replayed payment signatures may be rejected
- Network or RPC issues on Base may delay payment settlement confirmation
- result.ok=false indicates handler-side failure even if payment succeeded

## How this service works

Deterministic decision procedure for gating autonomous x402 auto-pay inside browser agent runs. Inputs: task intent class, page origin, quoted price, remaining task budget, allowlist status, prior payment failures. Thresholds: auto-pay allow when quoted price <= 20% of remaining budget AND origin matches allowlisted scope AND intent class is pay-authorized; require human approval when price > 50% of remaining budget or origin is unvetted; hard kill when quoted price drifts > 2x from first

## Output

A JSON payload containing a structured decision procedure brief for browser execution payment gating, including handler success status, a result payload with key/value guidance, the service slug, an ISO-8601 generatedAt timestamp, payment confirmation details, and the K-2SO provider identifier.
