Options chain API, GET /

Which endpoints does the ApexVol API expose, and what does each one need?

Every endpoint with its method, path, plan, parameters, docs page and an example request. Returns the whole token surface as one JSON list. For each endpoint you get the HTTP method, the full path with its placeholders, the family it belongs to, the plan it needs, a one-line description, the query parameters with their defaults, the developer page that documents it and a request line that works as written. The family list, the endpoint count and links to the OpenAPI spec and the Markdown reference come with it. The list is read from the same records that build the developer pages, so it can never lag them. A client that holds a token can discover the API from this one call instead of a bookmarked docs page, and an unknown path answers with did_you_mean entries in this same shape.

The answer, in one call

Units first,
then the request.

No market data is involved. The response is the catalogue itself, and the call costs nothing against the monthly allowance.

Generated from the endpoint records at request time. The version and updated fields say which weekly capture the example requests come from.

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.

NameInDefaultRangeMeaning
No parameters.

Field by field

What each
number means.

endpoint_count
How many endpoints the list holds.
endpoints[].method, path
The HTTP method and the full path. {ticker} marks a path parameter.
endpoints[].tier
The lowest plan whose tokens can call it: basic, premium or pro.
endpoints[].params
The query parameters with their defaults, on one line.
endpoints[].docs
The developer page for the endpoint.
endpoints[].example
A request line that works as written, the one the docs sample was captured from.
families[]
The endpoint families with their page and endpoint count.
openapi, markdown
The OpenAPI 3.1 spec and the single-file Markdown reference.

Access, limits, errors

Before the
first call.

Plan
Basic Basic 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. The full list with payload shapes is on the errors page.
Since
API 1.17. 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.
