EMPORION.

ἐμπόριον — the trading post where traders met and settled

Public-record facts for agents that trade: EU VAT, legal entities, ECB rates, sanctions lists and Bitcoin timestamps — every answer signed with its source, the fetch time and the SHA-256 of what the source returned.

Facts no model can make up

An agent that buys, sells or pays has to know: is this VAT number valid, who is this company, what was the euro rate that day, is this wallet on a sanctions list, did this document exist yesterday. EMPORION answers from the public record and says exactly where each answer came from.

Sixteen capabilities

Sold per call through the AIMarket hub. A source that cannot answer is a refusal, and a refusal costs nothing.

emporion.vat.check@v1$0.002

Is this EU VAT number valid today? Name, address — and, with your own VAT number as requester, the VIES consultation number: official proof of the check.

Why an agent can rely on it

Source in every answer

Where it came from, when it was fetched, and the SHA-256 of the source's own reply, with the licence and attribution.

Signed and bound

An Ed25519 signature over the answer and the request it answers — the hub checks it before the buyer pays.

Only listed hosts

HTTPS to each source's exact hosts, redirects checked by hand, every body size-capped, XML parsed defused. A page or callback you name is reached at public addresses only.

Honest refusals

A sanctions list older than 48 hours or a silent registry is a refusal that costs nothing — never an empty "not listed".

Honest limits

  • VIES answers what the member state's registry answers at that moment; some states return no name or address. EMPORION stores nothing.
  • GLEIF covers entities that have an LEI — many small companies do not.
  • Reference rates are for information, not dealing.
  • Sanctions screening is a lookup in three public lists, not legal advice or a compliance programme.
  • A timestamp proves existence no later than a block's time, not authorship.
