What does an API call cost?

Calls are charged in CiteAbility™ Credits by banding, based on how many citations were checked. A claim request checks one citation; a URL request checks every citation found on the page.

What happens if my Credit balance is too low?

The API returns a payment-required response with the Credit amount needed, and does not run the check. Calls that cannot be completed are refunded.

Are Audit, Monitor and Watch available over the API?

Not today. The only confirmed public endpoint is the Score endpoint. Additional endpoints will be documented here when they are confirmed.

How do I get an API key?

Key takeaways.

One authenticated endpoint is confirmed today: POST /api/public/v1/score for a URL or a claim.
Requests are authenticated with an account-scoped API key sent as a Bearer token, and each key is rate-limited.
There is no subscription or setup fee; calls are billed in CiteAbility™ Credits by the number of citations checked.
Responses return the eight public dimension-level outputs; signals, weights and thresholds stay confidential.
CiteAbility™ cannot guarantee citation, recommendation, ranking or inclusion by any external AI system.

Endpoint

POST /api/public/v1/score

Send a URL for a page check or a claim for a claim score. Include an account-scoped API key as a Bearer token. The API is available to any account and each key is rate-limited. There is no separate subscription or setup fee; usage is billed through CiteAbility™ Credits at a flat rate for the number of citations a call checks.

URL request

curl -X POST https://citeability.ai/api/public/v1/score \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"url":"https://example.com/article","title":"Example article"}'

Claim request

curl -X POST https://citeability.ai/api/public/v1/score \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"claim":"A factual statement to assess","source_text":"Relevant supporting text"}'

Cost

What a call costs in Credits

Calls are charged at a flat rate for the number of citations checked. A claim request checks one citation. A URL request checks every citation found on the page. There is no separate subscription or setup fee.

Band	Citations checked	Credits
Small	1–5	8 Credits a call
Medium	6–20	33 Credits a call
Large	21–50	85 Credits a call
Bulk	51+	2.5 Credits a citation

Credits are the single currency across CiteAbility™, so the same balance covers API calls and in-app analysis. A call that cannot be completed is refunded. If a balance is too low, the API answers with a payment-required response and the required Credit amount instead of running the check.

Boundaries

Outputs support decisions; they do not control AI providers

CiteAbility™ does not claim adoption by unaffiliated AI providers. Each provider retains control over whether and how it uses any output. API responses do not guarantee citation, retrieval, ranking, recommendation or mention.
