Insynet API · v1

Insider trading,
congress trades
& 13F data.

A self-serve read API over the same regulatory pipelines that power the Insynet app: US & SE insider filings, US Congress (STOCK Act) trades, SEC 13D/13G filings, and hedge-fund 13F position changes — as clean JSON over HTTP, updated daily.

One bearer token. Five endpoints. No SDK required.

Quick start

Three steps to your first call.

Get a key

Subscribe and your key is issued instantly on the confirmation page; free keys by email. Keys look like isk_live_… and are shown once at issue time.

Send it as a bearer token on every request.

Make a call

Every endpoint is a plain GET returning JSON. Filter with ticker, since, and limit.

CORS is open, so it works from the shell, the server, or the browser.

Read the shape

Rows come back under data; request metadata (tier, freshness, remaining daily calls) sits under meta.

Order is newest business date first.

Get a key. Subscribe below for Hobby/Pro, or email us for a free key.

Pay by card and your key is issued instantly on the confirmation page. Free keys on request by email. Plaintext is shown once — we only store its SHA-256 hash.

Request an API key

Reference

The basics.

Everything an endpoint needs: where to send the request, how to authenticate, and how the response is shaped. These apply to all five endpoints.

Base URL

https://tlyddvcmpcbhotxhbiao.supabase.co/functions/v1/api-v1
All endpoints are GET. Responses are JSON. CORS is open (GET, OPTIONS). A custom domain (api.insynet.se) is planned.

Authentication

Send your key as a bearer token: Authorization: Bearer isk_live_…
The key is an Insynet-issued key (isk_live_ + 32 hex chars), not a Supabase JWT. We store only its SHA-256 hash; the plaintext is shown once at issue time and cannot be recovered — keep it safe. Missing, unknown, or revoked keys all return 401 (the response never reveals which).

Freshness

Your tier controls data freshness. On free, every endpoint only returns rows ingested more than 24 hours ago (meta.delayed = true). hobby and pro get the freshest data.

Ordering

Results are ordered newest business date first, then by ingestion time.

Query parameters

All five endpoints accept the same three optional parameters.

Param	Type	Default	Notes
`ticker`	string	—	Filter by symbol (1–12 chars of `A-Z 0-9 . -`), case-insensitive.
`since`	date	—	ISO `YYYY-MM-DD`; returns rows on or after this business date.
`limit`	int	`25`	Max `100`; values are clamped into `1…100`.

Response envelope

Every 200 response wraps rows in data and request metadata in meta.

Response envelope

{
  "data": [ /* endpoint-specific rows */ ],
  "meta": {
    "tier": "free",          // "free" | "hobby" | "pro"
    "delayed": true,          // true only on the free tier (24h delay)
    "count": 25,             // number of rows in this response
    "remaining_today": 74,   // daily calls left on your key
    "disclaimer": "Informational only. Not investment advice. Data may be delayed."
  }
}

Endpoints

Five endpoints, one shape.

Each endpoint returns rows under data and metadata under meta. All accept ticker, since, and limit. Examples below are illustrative.

Rate limits & errors

Two windows. Clear signals.

Two rolling limits are enforced per key: a per-minute window and a per-day window (rolling 24 h). Exceeding either returns 429 with a Retry-After header (in seconds) and a retry_after_seconds body field. meta.remaining_today on every 200 response tells you how many daily calls remain.

Status	`error`	Meaning
400	`bad_request`	Invalid `ticker` or `since` parameter.
401	`unauthorized`	Missing, unknown, or revoked API key.
404	`not_found`	Unknown endpoint path.
405	`method_not_allowed`	Non-`GET` method.
429	`rate_limited`	Per-minute or per-day limit hit — see `Retry-After`.
500	`internal_error`	Key lookup failed.
503	`unavailable`	Upstream data query failed.

429 Too Many Requests — error body

{
  "error": "rate_limited",
  "message": "Daily limit of 100 requests exceeded.",
  "retry_after_seconds": 3421

Data may be delayed. On the free tier all data is at least 24 hours old. Even on fresh tiers, upstream filings are inherently lagged (13F facts are ~45 days behind) and may contain errors, omissions, or restatements from the original filers.
