# SB 53 Frontier Scope Checker

`POST /v1/tools/check_sb53_frontier_scope`

## Request

- Base URL: `https://ainumbers.co`
- URL: `https://ainumbers.co/v1/tools/check_sb53_frontier_scope`
- Auth: none declared

Routes supplied model compute (FLOPs, as a decimal string above the 2^53 safe-integer range) and developer annual revenue through the California SB 53 Transparency in Frontier Artificial Intelligence Act (eff. 2026-01-01) scope thresholds: 10^26 FLOP frontier-model bar and $500M large-frontier-developer revenue bar. Returns in-scope flags and the triggered obligation set (transparency report, catastrophic-risk-assessment summary, and for large frontier developers the safety-framework publication, annual update, incident reporting, and whistleblower-channel obligations). Asserts a scope/obligation finding only, never that those obligations have been fulfilled. Standalone -- deliberately not folded into the CAIA/TRAIGA/AB2013 chains (narrow frontier-lab audience). Zero network, zero PII.
