## 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 aproxpay-heavy-session-pass-515b40bc -d '<json body>'
```

Example prompt: Get me a heavy residential proxy session routed through a US exit node — I need to scrape a site for about an hour and expect to use around 150MB of data.

## When to prefer this

Choose this endpoint when you need more than the 15MB/30-min entry session (/v1/session/entry) but don't need a full gigabyte. Ideal for mid-volume scraping jobs, one-off data collection runs, or any task expected to consume 15–200MB within an hour. For sustained, high-volume workflows exceeding 200MB, prefer /v1/session/gb. Use this over a direct fetch endpoint when you need full CONNECT tunnel control rather than proxied single-URL fetches.

## Known failure modes

- Payment failure or insufficient USDC balance — 402 Payment Required
- Invalid region code (not ISO 3166-1 alpha-2) — 400 Bad Request
- Requested exit region unavailable — 503 Service Unavailable
- Session pool exhausted — 429 Too Many Requests
- Credentials expire mid-session when 60-min or 200MB limit is reached

## How this service works

Heavy session pass: ephemeral CONNECT credentials (60 min + 200MB). For sustained volume use /v1/session/gb.

## Output

Returns ephemeral CONNECT proxy credentials (username/password, host, port) valid for up to 60 minutes or 200MB of bandwidth. The agent can immediately configure an HTTP CONNECT tunnel through the returned host:port using the supplied credentials. Session expires at whichever limit is hit first. For higher volume, the sibling /v1/session/gb endpoint offers up to 1GB.
