## Caveats

- Demo-led agent testing/backtesting platform (YC Spring 2026, Active); /pricing returns 404 and no rates are published anywhere (site, llms.txt, docs). It does not rent arbitrary compute: customers run their own agent command inside Chronicle's evaluation sandbox against service twins (simulated vendor APIs). Entry points: free signup and a 'Free Agent Audit'.
- 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.
- Documented limits: evaluation concurrency 1-32 trials (default 4); 8 agents and 200 trials per run; twins live 1-720 h (default 72, ttl_hours) and count against an org 'twin capacity' (403 when exceeded); 429 = 'Over the concurrency or trial limit'; 403 'Your organization doesn't have sandbox access' (sandbox access is gated per org). Capacity sizes per plan are not published.
- Free entry points exist (free signup at app.chronicle-labs.com, free agent audit), but no free-tier size, credit amount or paid tariff is published; free.* stay null.

## Regime table

| Regime | When it applies | How billed | Numbers | Source |
|---|---|---|---|---|
| Native service | Hardware and complete resource tariff unverified. | resource; CPU alloc, memory alloc | Unknown or native-unit billing; see facts below | https://chronicle-labs.com |

## Verified billing facts and gotchas

1. Public demo-led staging/evaluation environments; pricing path 404. Arbitrary compute versus managed service twins not established; no public rates.

## 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.
