For buyers
Proof you can check yourself
Everything below can be checked by you, not taken from us. Each page states what it establishes, and what it does not.
6 of the 6 need no account and no API key.
Signed snapshots and the transparency log
No account neededWhat it proves: That a dataset you were served has not been quietly rewritten since — the snapshot is signed, and the log it is recorded in is append-only.
How you check it: Run the verifier in your own environment. It uses the standard library only and imports nothing of ours, so a pass does not depend on trusting our infrastructure.
What it does not: A valid signature proves the bytes are unchanged. It does not prove the underlying figure was right when it was published.
Checks you can run before buying
No account neededWhat it proves: That the claims on this site survive being tested from outside, by someone with no account.
How you check it: The page lists each check as a command to run. It also lists, by name, the things about us that cannot be checked from outside.
What it does not: External checks cover what we serve. They cannot cover how we operate internally.
Real responses, no signup
No account neededWhat it proves: That the API answers with real Taiwan market data before you give us an email address.
How you check it: Send a request from the page and read the response. It is the same gateway a paying customer calls.
What it does not: The free tier carries one month of history, so depth is not what this demonstrates.
The agent evaluation set
No account neededWhat it proves: That an agent's answers can be scored against questions with known answers, including whether it looked at data it should not have.
How you check it: Take the question set and run it against your own agent. The scoring is described, not just the score.
What it does not: A benchmark measures the questions it contains. It is evidence about those, not a general guarantee.
Which evidence answers which obligation
No account neededWhat it proves: That when your second line asks where the data came from and whether it changed, there is a specific artefact to hand them.
How you check it: Read the mapping against the obligation you actually have to satisfy, and follow the link to the artefact.
What it does not: Nothing in it is an endorsement by any regulator, and it is not compliance advice. The obligation stays with you; we supply evidence.
The security questionnaire, answered
No account neededWhat it proves: That the standard vendor questions have written answers, including the ones where the answer is no.
How you check it: Read it against your own vendor checklist. Where a control does not exist, it says so rather than omitting the row.
What it does not: It is a self-assessment, not a third-party certification, and it is labelled that way on the page.
