The hosted API is live

There is no waitlist any more. The API is open, the free tier is self-serve, and the documentation is at https://api.attestwire.com/docs.

Start in one call

100 documents a month, no card, one key per email address. The plaintext key comes back once and cannot be recovered — store it before you carry on.

POST /v1/keys

curl -X POST https://api.attestwire.com/v1/keys \
  -H 'content-type: application/json' \
  -d '{"email":"you@example.com"}'

POST /v1/validate — an invoice in, a list of teaching errors out, the same payload shape as the library.
POST /v1/generate — the JSON invoice model in, XRechnung UBL out (EN 16931 core, xrechnung-ubl and peppol-bis-3 profiles).
Paid plans, self-serve: $49 for 2,500 documents a month, $199 for 25,000.

What it does not include: transmission. See what this is not.
