MiCA compliance API: enforcement vs. scoring
Most "compliance" tools built for crypto agents score or monitor a transaction after it has already happened. A compliance enforcement API evaluates the action before it executes and can refuse to let it proceed. The difference is not semantic — it is the difference between documenting a violation and preventing one.
Two categories of product
- Evaluates after the fact, often post-settlement
- Produces a risk score or alert
- Requires a human or downstream system to act on the signal
- Cannot itself stop the transaction
- Evaluates before the action executes
- Returns APPROVE / DENY / REQUIRE_APPROVAL
- DENY means the request never reaches the upstream target
- Every decision is hash-chained for audit, whatever the outcome
What this looks like as an API call
An agent (or the proxy in front of it) submits the proposed action. The decision comes back before anything is sent to the bank, exchange, or on-chain program:
curl -X POST http://localhost:3001/v1/actions \
-H "Authorization: Bearer <agent-secret>" \
-H "Content-Type: application/json" \
-d '{
"action": {
"rail": "x402",
"amount": { "value": 500, "currency": "USD" },
"timestamp": "2026-07-06T00:00:00Z"
}
}'
# 200 OK
# { "decision": { "outcome": "DENY" }, "record": { "record_id": "...", "self_hash": "sha256:..." } }Because the response is returned synchronously in the request path, the agent's code path can branch directly on decision.outcome — there is no polling loop waiting for a scoring service to flag the transaction hours later.
Why this matters for MiCA
MiCA Title V Chapter 2 (Art. 66-73) requires CASPs to run governance, AML/CFT, and safekeeping controls, not just report on them retrospectively. Article 68 in particular calls for systems and procedures to detect and prevent money laundering and terrorist financing — prevention is a pre-execution property. A scoring tool alone satisfies detection; it does not, by itself, prevent anything.
