Programmatic read access to the published index. Keys are self-serve from your account page — no sales call, no approval queue. The same rule as the site: every number is a dated observation, never an estimate.
Create a key at /account (shown once, starts with vix_)
and pass it as a bearer token:
curl https://vix.devop.live/api/v1/companies \
-H "Authorization: Bearer vix_…"| Endpoint | Auth | Returns |
|---|---|---|
GET /api/v1/companies | API key | Every published company with scores, stage percentile, latest-round facts,
hiring and adoption metrics. as_of stamps the read;
last_observed_at dates each row's newest evidence.
Params: updated_since (ISO date/datetime — only rows whose
evidence changed since; poll with your last as_of),
limit (≤5000), offset. Response carries
total for paging. |
GET /api/export/index.csv | none | The same top-line table as spreadsheet-ready CSV — free, no key. |
