Developer API — coming soon
One balance.
The site and the API.
There are no monthly API plans. API calls will draw from the same prepaid credits you use on faxtr.com — top up once, use them anywhere. Credits never expire.
What each API call will cost
The same credits as on the site. Prices are set so that each call stays well above what it costs us to run.
| Endpoint | What it does | Credits |
|---|---|---|
| /v1/claims | Search published fact-checks for a claim or keyword | 1 per 10 calls |
| /v1/verify | Check one claim against government releases and news reports, with sources | 5 per claim |
| /v1/guard | Find checkable claims in a piece of text (e.g. AI-generated answers) and match them to fact-checks | 1 per request |
| /v1/scan | Run the Scanner on a photo, feed video or live stream | Same as on the site: photo 5 · feed video 8 · live 10 per 5 min |
Credit packs
The same packs for people, businesses and developers.
Frequently asked
Is there a monthly fee for the API?

What happens when my balance runs out?
Calls return HTTP 402 until you top up. We never charge your card automatically.
Do failed calls cost credits?
No. If a check fails on our side, the credits are returned automatically.
Do credits expire?
No. Paid credits never expire. Unused credits can be refunded within 7 days of purchase.
