IPO Tracker API

A JSON API for pre-IPO, IPO and newly-public company data. Base URL: https://ipotracker.app/api/v1. Every key needs an active subscription — see plans.

Authentication

Send your key as a Bearer token (the X-Api-Key header is also accepted). Keys are shown once at creation and stored hashed — keep them secret and server-side.

curl https://ipotracker.app/api/v1/companies \
  -H "Authorization: Bearer ipo_live_xxxxxxxxxxxxxxxx"

Errors

Errors use a consistent envelope with a stable machine code:

{ "error": { "code": "unauthorized", "message": "Missing or invalid API key" } }

Status	Code	Meaning
400	invalid_request	Malformed query or body.
401	unauthorized	Missing, unknown or revoked key.
402	payment_required	No active subscription.
403	plan_limit	Request exceeds your plan.
404	not_found	Unknown endpoint or resource.
429	rate_limited	Per-minute rate limit hit.
429	quota_exceeded	Monthly quota hit.

Rate limits & quota

Each response carries X-RateLimit-* (per minute) and X-Quota-* (per month) headers. On 429, respect the Retry-After header.

X-RateLimit-Limit: 60
X-RateLimit-Remaining: 42
X-Quota-Limit: 100000
X-Quota-Remaining: 99123

Pagination

List endpoints accept limit and offset and return { items, total, limit, offset }. Invalid values return 400.
