Returns PASS/FAIL/INVALID and a receipt a second party can check at /check. Planning and math verification check only — not a licensed professional engineering review, |
run_formula | Run one of our built-in physics formulas (sound speed, echo range, drop shock, field magnitude, thermal, timing and more) on YOUR inputs. Find formula codes and their input names with discover_capabilities. Every formula reproduces its own reference example before it is listed. Each result carries i |
run_chain | Run up to 8 checks or formulas in one call and get ONE signed bundle receipt. Each step is either a verify_math_or_tolerance argument object or {formula, inputs}. Planning and math verification check only — not a licensed professional engineering review, stamp, or sign-off. |
quote | Exact credit price of any capability before you spend anything. Free. |
verify_report_receipt | Check that a Checkbooth receipt is genuine and unchanged. Free, no key needed. |

seal_bundle_receipt | Verify 2 to 20 of your Checkbooth receipts and seal them into ONE signed design-review bundle with a single /check link. |
verify_trig_expression | Recompute a formula that uses trig (sin, cos, tan, asin, acos, atan; degree forms sind, cosd, tand, asind, acosd, atand) and compare it to a target. Signed receipt. Planning and math verification check only — not a licensed professional engineering review, stamp, or sign-off. |
audit_text_rounding | Paste text (up to 8,000 characters). We find every inline "arithmetic = number" claim and recompute it at the stated digits. Signed receipt. We keep only hashes of your text. |
verify_claims_against_receipts | Paste a README, PR description, spec or memo plus the Checkbooth results it relies on. We check every number in the text against those signed results and flag overclaim phrases (for example "verified across all conditions", "guaranteed", "certified"). Deterministic, no AI. Signed receipt. |
issue_sandbox_key | Get a free capped beta key (cb_test_...). Shown once; we keep only its hash. |
