## Caveats

- Fully managed, managed BYOC AWS, and self-hosted AGPLv3 or commercial license. Public product, contact-sales prices all modes. TDX/SEV/TPM advertised coming in 2026, not established available by crawl.
- 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.
- Refund policy: all fees non-refundable once charged (subscriptions, usage-based charges, professional services); cancellation keeps access to end of billing period with no pro-rating; trials/POC credits have no cash value. Terms reference 'subscription and usage billing' but no public numbers.

## Verified billing facts and gotchas

1. Fully managed, managed BYOC AWS, and self-hosted AGPLv3 or commercial license. Public product, contact-sales prices all modes. TDX/SEV/TPM advertised coming in 2026, not established available by crawl.

## 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.

**Total: unknown.** This product does not publish a verified complete 4-vCPU/8-GiB tariff and/or the service bills a different unit. Fifty concurrent instances and eight-hour sessions are not automatically supported. Neither 30% utilization nor retained snapshots can be converted into free resources. Use the native plan terms above and request the missing CPU/RAM, retention, egress and concurrency quote.

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.
