Updated: 2026-11-15

On 15 Nov 2026 TheRundown, ParlayAPI, The Odds API, SharpAPI, SportsGameOdds and novigapi.com all issued free keys without a card. novigapi.com also lets an AI agent request a key itself: it calls start_signup, you approve a code at /connect, and the key is delivered once, with 100 credits a month.

A no-card key lets you test the shape of the data before you commit. Check the free tier's delay and history window, because they differ more than the quotas.

## How the options compare

## Where novigapi.com falls short

> Our 100 free credits run out faster than ParlayAPI's 1,000 or The Odds API's 500 if you page through large lists.

## Try it

Agent signup: the response carries a user_code and an approval_url for the person to approve; the agent then polls /api/v1/agent/token for the key.

```bash
curl -s -X POST https://novigapi.com/api/v1/agent/signup \
  -H "Content-Type: application/json" \
  -d '{"data_wanted":"NFL props with fair prices","use_case":"weekly model","agent":"Claude Code"}'
```

## Questions

### Can an AI agent get a novigapi.com key?

Yes, through the agent signup flow: the agent starts it, a person approves the code, and the key is shown once.
