OIG guidance says screen every employee, contractor, and vendor against the LEIE every month — one excluded person on a billed claim can mean Civil Monetary Penalties (≈$22K per claim + treble damages). Drop your roster in, get back a dated, cryptographically-signed compliance receipt that proves who you screened, against which list build, on what date. OFAC + SAM screened in the same pass. $19/mo · API + MCP + x402

POST /api/roster (or the roster_rescreen MCP tool) — it mints the signed receipt below.This is what an auditor asks for — proof the monthly check happened. Each roster re-screen mints an ed25519-signed, content-hashed receipt: tamper-evident, verifiable offline against our public key, and pinned to the exact list build it ran on. Verify any receipt at /receipt/<id>.

OIG recommends checking the LEIE monthly for everyone you bill or pay. We re-screen the whole roster and time-stamp it — so "did we screen in month X?" has a signed answer.
Healthcare exclusion (OIG-LEIE), sanctions (OFAC SDN + Consolidated), and federal debarment (SAM.gov) — deduped into one verdict per person.
Signed, hash-chained, offline-verifiable. Pinned to the exact list build. The artifact that survives an audit, not a screenshot.
MCP tools roster_rescreen + screen_exclusion — a compliance agent runs the monthly check and files the receipt itself. Pay-per-call via x402 (keyless USDC on Base) or subscribe.
