GET /v1/accelerators

The Accelerator lane: new cohort companies (Y Combinator, a16z speedrun, South Park Commons, Founders Inc, Z Fellows and more) as we detect them, often before the directory lists them, stealth teams included. One row per company, with program, batch, sector, one-liner, website and founders.

Cost: Draws on your monthly usage. Empty answers are free.

Availability: Plans that include the accelerator lane (see Pricing). Other keys get 403 lanes_not_enabled or 403 accelerator_lane_not_enabled. GET /v1/status → lanes.accelerators tells you before you call.

Parameters

Parameter	Type	Default	Description
`since`	string (query)	`30d`	Window: `7d`, `30d` or `YYYY-MM-DD`. Max 90 days.
`program`	string (query)	--	One accelerator key, e.g. `yc`, `speedrun`, `spc`, `finc`, `zfellows`. The `programs` block in any response lists what is there.
`batch`	string (query)	--	Batch text match, e.g. `Fall 2026`, `SR008`.
`stealth`	boolean (query)	--	`true` = stealth teams only, `false` = named companies only.
`q`	string (query)	--	Search name, handle, one-liner, sector, founder names.
`scope`	string (query)	--	`tracked` or `list:<id>` decides whose followers `followed_by` names. Cohort membership is a fact, not a follow, so scope never removes companies.
`limit`	integer (query)	`50`	Max rows (max 100).
`offset`	integer (query)	`0`	Pagination offset.
