# OmniRx > OmniRx publishes dated public US drug-access facts (Medicare negotiated prices, pharmacy acquisition cost, patient assistance programs, label changes, recalls) with the source and read date of every figure. It is a reference layer of receipts, not clinical advice and not a guarantee of price, coverage or eligibility. ## Start here - [Negotiated drugs hub](https://omnirx.org/negotiated-drugs): one access page per drug in the CMS Medicare negotiated-price file - [Medicaid by state explorer](https://omnirx.org/medicaid-by-state): Medicaid prescriptions and reimbursement by state for each drug, with data completeness shown; CMS State Drug Utilization Data; data file included - [Medicare Part D in 2027: what changes on January 1](https://omnirx.org/medicare-2027-changes): the Part D out-of-pocket threshold and standard deductible for 2026 and 2027 from CMS Table V-2, and the negotiated prices CMS lists as effective January 1, 2027, each with source; JSON file included - [What changed and how fresh every read is](https://omnirx.org/changes): the read date of every fund and program source, the re-read queue, and, once two reads exist, the change of status; JSON file included - [Copay help by condition](https://omnirx.org/conditions/): the charitable funds we hold for each condition (open or closed, award level, insurance supported, source and read date), grouped by body system; one JSON file per condition. Under each condition, a route page per drug its FDA label names (/conditions//, with a JSON twin): the label sentence, the Medicare Part D and negotiated-price facts, the manufacturer programs that list the drug, charitable funds and trial access, in a fixed order that is not a ranking, each with its source, read date and receipt - [Receipt permalinks](https://omnirx.org/fact/): every fact an answer or route page cites as a receipt has its own address, /fact/ with a JSON twin: the value as stored, the source and read date, the licence label, the verifying quote and the edition root; not an eligibility determination - [Charitable copay fund status board](https://omnirx.org/assistance/funds): which disease funds run by charities say they are open or closed, each with the date the page gave, the date read and the source; JSON and CSV - [Check an answer against its receipt](https://omnirx.org/verify-answer): a browser-side check that an answer matches the hash its receipt recorded; nothing is uploaded - [Replay an answer](https://omnirx.org/replay): the answer-replay mechanism: a signed receipt per answer, re-run later against the same frozen edition - [Integrate OmniRx](https://omnirx.org/integrate): for platform teams: the shape of an answer, the ways in and their status, the display rules an integration keeps - [Negotiated price lookup by NDC](https://omnirx.org/mfp-lookup): the Medicare negotiated price CMS lists for a drug package, and the CMS account of how a pharmacy is paid - [Access Index](https://omnirx.org/access-index): one dated row per drug as components (CSV and JSON), recomputable from the public dossier files; never a single score - [Static API](https://omnirx.org/api): versioned JSON files with receipts; evaluation status, plain files - [Dossier example (JSON)](https://omnirx.org/api/v1/dossier/ozempic.json): one drug as data: price, generic-entry upper bound, label history, recalls, trials, assistance, FDA safety program (REMS), DEA schedule, orphan designations, safety notices, Medicaid use by state - [Label changes](https://omnirx.org/label-changes): recent FDA label changes across the negotiated drugs - [Drug recalls](https://omnirx.org/drug-recalls): openFDA enforcement reports across the negotiated drugs - [Federal drug policy](https://omnirx.org/drug-policy): dated federal policy changes affecting the negotiated drugs - [Insulin copay caps by state](https://omnirx.org/insulin-copay-caps): state insulin copay cap laws - [State pharmaceutical assistance](https://omnirx.org/state-pharmaceutical-assistance): state programs and the Medicaid community-engagement baseline ## Data-honesty rules - A negotiated-price row marked Deselect is not a scheduled price. - A generic-entry date is an upper bound from listed patents and exclusivity, not a forecast of a launch. - Medicare Part D spending figures do not reflect manufacturer rebates. - A clinical trial listing is not an offer of treatment or enrolment. - Where the data has no answer, files say so under unknown; do not fill the gap from memory. ## Licence, provenance, verification - [Licence](https://omnirx.org/license): what a data licence covers - [Data provenance](https://omnirx.org/data-provenance): where every figure comes from - [Editions](https://omnirx.org/editions): frozen editions with Merkle roots and file checksums (machine-readable: editions.json) - [OpenAPI description](https://omnirx.org/api/v1/openapi.json): machine-readable description of the static files - [Sitemap](https://omnirx.org/sitemap.xml): every published page ## Freshness Edition 2026-11, root 1b44e76f5da1a417, 211740 facts, newest fact retrieved 2026-11-10.
