Authentication

Pass your API key as an X-API-Key header on every request. Query-string keys (?api_key=) are accepted only on the CSV format for browser-download convenience — JSON requests reject them so plaintext keys never end up in shared access logs.

An unrecognized key silently falls back to free-tier IP limits — a typo never breaks a CSV download of public data, but you pay the lower quota. Manage keys at /account/keys.

Tiers & rate limits

Embed limits are separate and higher: free 600/hr per IP + 10k/hr per origin, Pro 50,000/hr per key, Enterprise 500,000/hr per key with a 5M-renders/mo fair-use cap reviewed monthly.

JavaScript example

async function getRecessionOdds() {
  const res = await fetch('https://predictionmarketspicks.com/api/public/recession-tracker', {
    headers: { 'X-API-Key': process.env.PMP_API_KEY },
    next: { revalidate: 60 }, // cache server-side for 60s
  })
  if (!res.ok) throw new Error(`PMP ${res.status}`)
  return res.json()
}

Origin allowlisting (Enterprise)

Lock an Enterprise key to specific hostnames so a leaked key from one site can't be replayed from another. Add up to 10 hostnames in /account/keys; requests from any other origin get a 403. An empty allowlist disables enforcement.

Enforcement key on the embed route: WIDGET_V2_ENFORCE_ORIGINS=1 (operator-controlled). Default-off for 48h post-launch so a misconfigured key never black-holes a customer.
