Price API
A public, versioned JSON endpoint carrying every tracked figure with its evidence grade and source URL. No key, no rate limit, CC-BY.
A public JSON endpoint at /api/prices.json carrying every tracked tirzepatide programme with all-in cost at each dose, evidence grade, source URL, disclosure score and the catch on each advertised figure. No key, no rate limit, CORS enabled, CC-BY.
Captured 2026-08-05. Regenerated on every build, so the endpoint and the pages cannot disagree.

/api/prices.json— every programme, full record/api/cheapest.json— the ranked list with the watchout on each figure/data/provider-price-index.csv— flattened for spreadsheets
What every record carries
All-in monthly cost at each of the six dose tiers, the starting and maintenance figures, a first-year total, cost per milligram, pricing model, membership, prepaid rate and term, pharmacy disclosure and whether a pharmacy is actually named, visit model, laboratory requirement, cancellation terms, disclosure score, evidence grade, the source URL we read the figure from, a Wayback lookup, the catch on the advertised figure, and any documented service reports.
How to cite it
State the dose and the capture date with any figure. Do not present a source-verified figure and a
third-party one as equivalent — the evidence_status field exists precisely so that
distinction survives. Attribution to GLP-1 Tirzepatide Price Guide under CC-BY.
Why this exists
Because an answer engine parsing a comparison page has to infer whether a number includes a mandatory membership, which dose it describes and when it was captured. Those three facts change the figure materially and are usually not machine-readable anywhere. Here they are fields.
It also means a claim on this site can be checked without reading the site. Sort the file on
first_year_total and our published ranking should reproduce exactly. If it does not, that is
a bug and we want to know.
First-year all-in cost
Open these rather than taking our word for it. Every one is a regulator, a trial registry, a label, an accreditor or the manufacturer.

The matrix carries all-in price at every dose, fee structure, commitment terms, pharmacy disclosure and verification status for every programme we track.
