API · HALT — the claim board for tokenized stocks

Public tier: 60 requests an hour per IP, cached for 60 seconds. Every list endpoint takes page (from 1) and limit (default 50, hard maximum 50) and answers with { items, page, per_page, total, next }. If you need more than that, the whole board is four calls; please cache it rather than looping.

01/api/v1/board

The board: one row per tokenized stock with its claim status.

Param	Values
`status`	open (default) · unclaimed · claimed · contested · abandoned · all
`sort`	spot (default) · meme · claims · symbol · recent
`q`	match on ticker, company name or claiming meme
`page`	from 1
`limit`	default 50, max 50
