## Caveats

- Browser agent step $0.005; plans include API credits, not guaranteed browser CPU/RAM hours. Enterprise custom. A step-to-hours conversion cannot be inferred.
- No invented browser vCPU or memory allocation: normalized 4/8 rate remains null. Proxy traffic is not necessarily equivalent to sandbox egress.
- Null values mean unknown, not free/unlimited. No model-token cost, tax or unverified ancillary charge included.
- Native browser/device/task/credit prices with unknown CPU/RAM are deliberately non-priceable. Check regime before interpreting any partial resource estimate.
- Only published meter is $0.005 per agent step (docs.smooth.sh/pricing, re-checked 2026-09-28); no per-browser-hour or per-resource rate exists, so the card stays unpriced for hour-based workloads. Free plan: $5 welcome credit. Starter concurrency: pricing page says 10 browsers, docs say 5 (card keeps 10).

## Verified billing facts and gotchas

1. Browser agent step $0.005; plans include API credits, not guaranteed browser CPU/RAM hours. Free welcome credit amount not stated; Enterprise custom. A step-to-hours conversion cannot be inferred.
2. No invented browser vCPU or memory allocation: normalized 4/8 rate remains null. Proxy traffic is not necessarily equivalent to sandbox egress.

Native pricing (not coerced into incompatible engine units):
```json
{
  "browser_hour_usd": null
}
```

## Worked example

Requested: 4 vCPU/8 GiB, 50 simultaneous × 8 h/day × 22 days = **8,800 instance-hours**, 30% CPU; 50 GiB snapshots and 100 GiB egress. A month is 730 hours only when explicitly used in rate conversion.

A 4-vCPU/8-GiB VM is not established by the browser offering. Native plan/runtime billing is documented above; no honest general-VM monthly total can be calculated.

Page captures and documentation indexes/bundles are in `raw/`; provider JSON lists the evidence paths. HN query results were captured separately as `<id>--hn.txt`; they are discovery leads, not current tariff authority. Downloaded docs do not imply every feature was verified; unsupported assertions remain null.
