Build on the signal layer.

Session-based, tier-aware.

Public endpoints are callable without credentials and return a locked teaser shape. Requests made from a signed-in browser session return the full payload your subscription tier allows — Free accounts see full signals after a short delay window; Pro and Elite see them instantly. For server-side integrations, the Partner API uses scoped Bearer keys (mkpk_…) — see the Partner API section below.

GET /api/v1/signals HTTP/1.1
Host: markitel.com

# anonymous → 200, teaser shape (levels locked)
# signed-in Pro/Elite browser session → 200, full payload

Copy-paste ready.

const r = await fetch(
  "https://markitel.com/api/v1/signals?include=closed",
);
const { signals } = await r.json();
// anonymous callers receive the teaser shape
console.log(`${signals.length} signals`);

import requests

r = requests.get(
    "https://markitel.com/api/v1/signals",
)
signals = r.json()["signals"]
print(f"{len(signals)} signals (teaser shape)")

Keyed access for partners.

Approved partners (IBs, distribution channels) get scoped API keys for server-to-server access. Send your key as Authorization: Bearer mkpk_…. Keys are scoped least-privilege: read:stats for referral aggregates and read:signals for the full redistribution feed (a stats-only key cannot reach signals). The full contract is published as a machine-readable OpenAPI schema, and a zero-dependency TypeScript SDK wraps it.

# Machine-readable contract — codegen a client
GET https://markitel.com/api/v1/partners/openapi.json

import { MarkitelPartnerClient } from "@markitel/partner-sdk";

const client = new MarkitelPartnerClient({ apiKey });
for await (const s of client.iterateSignals()) {
  console.log(s.asset, s.direction, s.entry_price_low);
}

The OpenAPI schema is public; the SDK ships with the partner program (distributed directly to approved partners with their key). read:signals is granted to contract-approved partners. Become a partner to request access, or follow the step-by-step connect guide. Approved API access is governed by the Partner Program Terms, API and SDK Terms, and Data Processing Addendum where partner-directed personal-data processing applies.
