§ 01How it works

Automated Audits with Event-Driven Callbacks.

01 — Inbound

eIDAS Introspection

Forward any QWAC or QSealC PEM for instant chain-of-trust verification. We validate QTSP signatures and extract all PSD2 attributes in a single atomic pass.

INPUTX.509 + PSD2 ext.
02 — Verify

Chain & Revocation

Full-path validation against EU Trust Lists with OCSP and CRL fallback. Zero-cache policy: every check uses live-refreshed anchors (updated hourly).

SOURCESTSL · OCSP · CRL
03 — Confirm

Regulatory Standing

Real-time mapping of licenses and cross-border permissions. We bridge the gap between national registers to confirm an entity's standing in your target markets.

REGISTERSEBA · FCA · NCA
04 — Gate

Deterministic Enforcement

Cryptographically signed results with hash-chained provenance. Traceable to source records and tamper-evident—providing immutable grounds for your enforcement.

v5 · the gate that calls you back

Two modes. Same answer. One contract.

Pull was the standard. Push is the answer. We've rebuilt the layer between.

PULL/v5/validate · per request

You ask, we answer.

Submit incoming certificates to ourendpoint and apply your own compliance ruleset on our responses. Simple, synchronous, works today.

§ 02Compliance

Built for what is. Ready for what comes. The day it comes

PSD2Directive 2015/2366
Every AISP, PISP and CBPII interaction across 31 EU/EEA jurisdictions. We validate Article 34 attributes — authorization number, PSD2 role, NCA — against live EBA and national registers on every request. Because a cert issued 18 months ago doesn't prove the license is still active today.
● Active
PSD3Proposal 2023/367
PSD3 folds EMIs into payment institutions as a sub-category. Thousands of re-authorized entities, new role combinations, updated capital thresholds. Our validation schema is already parameterized per regime — flip the version header, get the PSD3 verdict. No code change on your side, no waiting for your vendor to catch up.
◌ Ready
PSRRegulation (EU) TBD
The PSR harmonises conduct rules across the union — same API access requirements, same fraud reporting, same liability. But your stack was built for 27 national flavours of PSD2. We run the single harmonised ruleset, returning one consistent verdict regardless of which member state the TPP is passporting from. Swap the header, swap regimes.
◌ Ready
FIDAFinancial Data Access
Beyond payments: mortgages, pensions, investments. FIDA makes you a data holder for every authorized FISP — continuously, in real time. With no single EU-wide register for FISP authorization across schemes, jurisdictions and permissions, you need a trusted layer that does the lookup on every call. That's us. Signed verdict, cached briefly, refreshed the moment anything changes.
◌ Ready
eIDAS 2.0Regulation (EU) 2024/1183
EUDI Wallet trust anchors, qualified attestations, cross-border identity. eIDAS 2.0 isn't replacing QWACs — it's extending the trust framework around them. We refresh every EU/EEA trust list every 15 minutes, verify the LOTL integrity on every pull, and surface the underlying QTSP chain so your compliance team can audit any verdict back to its regulatory source.

LIFECYCLEmanage subscriptions

        
Your subscription, your rules.

        
Every webhook subscription emits its own lifecycle event. You always know whether your endpoint is live, whether a URL change landed, and when an unsubscribe takes effect — confirmed by a signed callback, not a silent KV write.

      


      


        
        

          
CREATEor heartbeat

          
POST a cert with a webhook_url. First time registers the subscription. Same URL again = heartbeat ping that confirms your endpoint still works end-to-end.

          
{
  "event_type": "webhook.subscription_created",
  "data": {
    "webhook_url": "https://bank.eu/hooks/tpp",
    "issuer_hash": "34b00ae80ada1f90",
    "serial": "107134...",
    "entity_name": "Plaid, B.V."
  }
}

        


        
        

          
UPDATEchange URL

          
POST the same cert with a different webhook_url. We swap the destination atomically and deliver one confirmation event to the new URL with the previous one in the payload.

          
{
  "event_type": "webhook.subscription_updated",
  "data": {
    "webhook_url": "https://bank.eu/hooks/tpp-v2",
    "previous_webhook_url": "https://bank.eu/hooks/tpp",
    "issuer_hash": "34b00ae80ada1f90",

DELETEunsubscribe

          
Send DELETE /v5/subscriptions/{issuer_hash}/{serial} with your bearer token. We remove the subscription and deliver one final goodbye event to the URL that was registered.

          
{
  "event_type": "webhook.subscription_deleted",
  "data": {
    "webhook_url": "https://bank.eu/hooks/tpp-v2",
    "issuer_hash": "34b00ae80ada1f90",
    "serial": "107134..."
  }
}

        


      


      

        
        List all your active subscriptions: GET /v5/subscriptions — returns lastDeliveredAt and lastDeliveryStatus per entry.
