API/ FREE TRIAL100 FREE CALLS / DAYNO SIGNUPNO KEY, NO WALLET

Try the Premium API, Free

Every IP gets 100 premium API calls per day. No signup, no API key, no wallet, no credit card. Just call the endpoint.

Most paid data APIs make you create an account, verify an email, and paste a credit card before you can see a single response. TerminalFeed does the opposite. Every IP address gets up to 100 free calls to any premium /api/pro/* endpoint per 24-hour rolling window, with no authentication header at all. Evaluate the entire premium surface before you ever think about paying.

ONE CALL, NO SETUP

Call any premium endpoint with no Authorization header and the free-trial counter increments automatically:

# A composed world snapshot: BTC + Fear & Greed + earthquakes + HN + prediction markets
curl https://terminalfeed.io/api/pro/briefing

# Or from JavaScript / an agent runtime
fetch("https://terminalfeed.io/api/pro/briefing")
  .then(r => r.json())
  .then(console.log)

That is the whole onboarding. No dashboard, no key rotation, no SDK install.

CHECK YOUR REMAINING QUOTA

The status endpoint is free, needs no auth, and does not consume a call:

curl https://terminalfeed.io/api/free-tier/status

{
  "ok": true,
  "free_trial": {
    "calls_per_ip_per_day": 100,
    "window": "24h rolling per IP",
    "auth_required": false,
    "used_today": 0,
    "remaining": 100
  }
}
EVERY PREMIUM ENDPOINT IS INCLUDED

The free trial applies to all premium endpoints, not a stripped-down sample:

EndpointWhat it composes
/api/pro/briefingBTC + Fear & Greed + earthquakes + HN + Polymarket
/api/pro/macroFed rate + CPI + treasury yields + forex + commodities (oil, nat gas)
/api/pro/agent-contextPaste-ready system_prompt of the current world state
/api/pro/correlation-matrixComputed correlations across FRED macro series
/api/pro/world-deltasEvents newer than a timestamp you pass
/api/pro/github-velocityTrending repos with a computed velocity score
WHAT HAPPENS AFTER 100 CALLS

When the daily cap is reached, the endpoint returns the canonical x402 V2 402 Payment Required challenge with free_trial.status set to "exhausted" and a resets_at timestamp. Your quota refills on a rolling 24-hour window, so you can keep evaluating day to day. When you are ready for production volume, top up credits with USDC on Base mainnet:

  • 1 credit = $0.02. Most endpoints cost 1 to 2 credits.
  • No subscription. Pay per call, scale up and down freely.
  • One token, two sites. The same credits work on TensorFeed.ai (AI model intelligence and news) from the same pool.
No human in the loop. The trial needs no email and no card, and production access is a wallet transaction, not a signup form. This is built for autonomous agents that have a wallet, not an inbox.
