## 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 paid-browser-task-acceptance-gate-for-x402-browser-providers-f646e9f4
```

Example prompt: Before I let you pay for that web scraping task, can you run it through the browser-task acceptance gate to grade the provider on sandbox isolation, budget sizing, retry caps, and kill criteria — I want to make sure it's safe to authorize the USDC spend?

## When to prefer this

Choose this endpoint when an AI agent is about to authorize per-task USDC spend on a browser-automation provider via x402 and needs a structured go/no-go assessment covering budget sizing, sandbox safety, retry policies, and pricing honesty. Prefer it over generic capability checks when the provider is unknown, the task involves mid-session paywall crossing, or the budget per task is non-trivial.

## Known failure modes

- Missing or invalid input type/method returns a schema validation error
- Endpoint called without payment returns HTTP 402 with payment required headers
- Topic override parameter ignored if malformed — falls back to default browser-task topic
- LLM-generated briefs may reflect stale heuristics if provider landscape has changed
- No dynamic endpoint probing — grades based on declared metadata, not live testing

## How this service works

Paid agent-facing procedure: pre-purchase acceptance gate for x402 browser-automation providers. Grades a browser-task endpoint on per-task budget sizing, sandbox isolation claims, page-state deliverable evidence, mid-session paywall crossing, retry caps, price honesty, and kill criteria before authorizing per-task USDC spend.

## Output

Returns a structured JSON object containing an acceptance decision (ok boolean), a prose decision brief for the agent, the service slug, topic evaluated, generation source (llm/reasoning/deterministic), an ISO-8601 timestamp, and payment confirmation details including transaction reference and payer address.
