How correlated are NVDA and AMD?

The assistant calls get_ticker_analytics and answers from the JSON below.

Tokens come with every paid or trial plan. Sign in and create one under Account, then API Access, or start a trial. Your ticker, your budget.

  "success": true,
  "data": {
    "ticker1": "NVDA",
    "ticker2": "AMD",
    "timeseries": [

Every response is wrapped as {"success": true, "data": {...}}. Lists in the sample are cut to a few rows so it fits on a page; the shape is exactly what your code receives.

Parameters

Bounded,
and the bounds are stated.

Out-of-range numbers are clamped to the documented range, never silently changed to something else. A missing required field returns 400 with the reason.

Access, limits, errors

Before the
first call.

Plan
Premium Premium and above. Tokens are issued to paid and trial accounts from $55 a month; each endpoint follows the tier of its web feature. An endpoint above your plan answers 402 and names the plan it needs.
Auth
Bearer token, prefix avmcp_, created under Account, then API Access. Shown once, hashed at rest, rotates in one click. Always call https://apexvol.com, never www.
Limits
60 requests a minute and 1,000 an hour per token, plus a monthly allowance by plan. Every response carries the remaining counts in X-RateLimit-* headers; a 429 carries Retry-After in seconds.
Errors
401 no or revoked token; 429 Retry-After seconds; 403 Premium plan required; 424 data feed unavailable, retry. The full list with payload shapes is on the errors page.
Since
API 1.0. Units, bases and timestamps follow the conventions shared by every endpoint; changes are logged in the API changelog.
Machine-readable
This page as Markdown, the family as one file, the whole API as llms-full.txt or OpenAPI 3.1.
