Terms of use

Zetesis is operated by Reut Rachel Avidan, a licensed business (עוסק מורשה) registered in Israel. Zetesis is a trading name, not a separate legal person. By using the service at api.zetesis.science you agree to these terms. Last updated 2 September 2026.

What the service does

Zetesis retrieves public scientific evidence about a stated claim and returns the questions a domain reviewer would ask, the failure patterns that have caught comparable claims before, and, where requested, a graded reading. Sources are public registers: Europe PMC, ClinicalTrials.gov, openFDA, NIH RePORTER and SEC EDGAR.

What a Zetesis reading is, and is not

A reading is an assessment of what the retrieved public record supports about a claim, as at the date it was produced. It is a research tool.

• It is not investment advice, medical advice, legal advice, or a regulatory opinion.
• It does not establish that a claim is true or false. It reports what the retrieved evidence does and does not show.
• Absence of evidence is reported as unshown, which is not the same as disproven.
• It is not a substitute for professional judgement or independent verification.

Decisions taken on the basis of a reading remain yours.

Accuracy and coverage

• Zetesis retrieves from the registers named above and nothing else. A claim resting on proprietary, unpublished or unindexed evidence will return as unshown.
• Upstream registers can be unavailable or incomplete. When retrieval is degraded the response says so, and the reading should be treated as partial coverage.
• Identifiers returned by the service are retrieved, not generated. We do not warrant that a register's own record is accurate.

Acceptable use

Do not submit content you are not entitled to share, attempt to extract credentials or other users' data, circumvent rate limits or authentication, or use the service in breach of applicable law. Free access is provided on a fair-use basis and may be rate limited or withdrawn.

Your content

You retain rights in what you submit. How it is processed, including which tools transmit content to a model sub-processor and which do not, is set out in the privacy policy.

Availability

The service is provided as is. We do not guarantee uninterrupted availability, and we may change, suspend or discontinue any part of it.

Liability

Nothing in these terms excludes or limits liability that cannot lawfully be excluded or limited, including liability for death or personal injury caused by negligence, or for fraud or fraudulent misrepresentation.

Subject to that, and to the maximum extent permitted by law:

• We are not liable for indirect, incidental, special or consequential loss, or for loss of profit, revenue, data, goodwill or business opportunity, however arising, whether or not we were advised such loss was possible.
• Our total aggregate liability for direct loss arising out of or in connection with the service is limited to the fees you paid for it in the twelve months preceding the event giving rise to the claim.

Where you use the service without charge, that limit is zero. That is a limit on money, not a disclaimer of the descriptions above: what a reading claims, and does not claim, applies whether or not you pay.

Changes

We may update these terms. Material changes are reflected in the date above.

Governing law

These terms are governed by the laws of the State of Israel. The competent courts of Tel Aviv-Yafo have exclusive jurisdiction over any dispute arising from them, save that either party may seek injunctive relief in any court of competent jurisdiction.
