# KYC Certificate
> Identity-verification certificate for consumer onboarding
The **KYC Certificate** is a reusable identity-verification certificate bundle
for consumer onboarding. It replaces per-bank KYC intake with a network-issued
attestation: instead of each institution re-running document capture, biometric
checks, and identity corroboration for the same person, a query assembles the
verification work already furnished by network participants into a single
certificate.
| | |
| - | - |
| **Category** | Identity Verification |
| **Use case** | Customer Onboarding |
| **Subject** | Consumer |
| **Operations** | `POST /v1/products/kyc_certificate_snapshot/query`, `POST /v1/products/kyc_certificate_snapshot/furnish` |
## What's in the certificate
A KYC certificate consolidates up to nine **sub-products**, each a block in the
query response with its own `assertions` (what was attested, and when) and
`data` (the supporting attributes):
| Sub-product | Response key | What it attests |
| - | - | - |
| Document capture | `document_capture` | An identity document was captured, with its type, number, and dates. |
| Document review | `document_review` | The document's attributes were reviewed — tamper and machine-readable-data checks. |
| Biometric capture | `biometric_capture` | A biometric artifact (e.g. a selfie) was captured. |
| Biometric review | `biometric_review` | The biometric was compared against a reference, with quality and outcome. |
| Liveness capture | `liveness_capture` | Liveness evidence was captured. |
| Liveness review | `liveness_review` | The liveness evidence was reviewed, with outcome and confidence tier. |
| Address capture | `address_capture` | A residential address was captured. |
| Address verification | `address_verification` | The address was verified, with method, outcome, and deliverability. |
| Identity corroboration | `identity_corroboration` | CIP-style corroboration — SSN, name, and DOB matches across sources. |
Every populated sub-product carries the `furnishing_entity_id` of the
participant whose data backed it and the `attestation_event_id` of their attestation,
so the certificate is auditable down to its sources.
## Querying
```bash theme={null}
curl -X POST https://api.solo.one/v1/products/kyc_certificate_snapshot/query \
-H "Authorization: Bearer $SOLO_TOKEN" \
-H "Content-Type: application/json" \
-d '{
"consent_id": "a3f0b9c7-…",
"policy_id": "5e7d2a14-…",
"network_ids": ["9f1c0c2e-…"]
}'
```
The request follows the standard [query anatomy](/api-overview/querying/overview.md):
identify the subject with `consent_id` (or `consumer_identity_id` for direct
permissible-purpose lookups), and scope the read with `network_ids` plus an
optional `policy_id` and `furnishing_entity_ids`.
A `200 OK` means a certificate was issued:

* `certificate_id` — the issued certificate. The certificate records the
date it was issued, its attestation timestamp, and the network + policy pairs
it was resolved under.
* `provenance_event_id` — the billable provenance event id; the same value is returned in
the `X-Ref-Id` response header. Quote it to support and keep it in your audit
log.
* `result` — the consolidated certificate. Sub-products the policy didn't
require (or that lacked data) are `null`. The per-source outcome counts
(`*_source_count_*`) are always `null`: furnishers report one outcome per
check, not one per source consulted.
## How the certificate resolves per network
```mermaid theme={null}
flowchart LR
A[Resolve subject
consent_id / consumer_identity_id] --> B[Gather furnished events
across network_ids]
B --> C[Apply querying policy
field + freshness filters]
C --> D[Pick oldest matching event
per sub-product]
D --> E{Policy requirements met?}
E -- yes --> F[Issue certificate · 200]
E -- no --> G[No certificate · 204]
```
The query gathers furnished events across every network in `network_ids` and
applies the querying policy's filters uniformly. For each sub-product it selects
the **oldest matching event** from any allowed network, and the result's
`meta.network_id` is anchored to the **first** network in your request — list
your primary network first. Which furnishers' data is considered, and which
fields you see, is further shaped by your
[entitlement](/concepts/governance/entitlement.md).
## When you get a 204
The endpoint declares a `204 No Content` response: *no certificate could be
created — the available data did not satisfy the policy requirements*. Concretely,
a `204` is returned when:
* a sub-product the policy requires was never furnished for this consumer in
the queried networks, or
* furnished data exists but fails the policy's filters (e.g. outside the
freshness window the policy selected), or
* the policy selected specific data fields that the resolved certificate could
not populate.
The body is empty. The response still carries the `X-Ref-Id` header, and the
query event is still recorded. To anticipate `204`s before spending a billable
query, run a [coverage check](/api-overview/querying/coverage-check.md) first.
## Furnishing
Participants contribute the underlying KYC data with
`POST /v1/products/kyc_certificate_snapshot/furnish`:
```json theme={null}
{
"network_id": "9f1c0c2e-…",
"application_date": "2026-05-28",
"records": [
{
"first_name": "Jane",
"last_name": "Doe",
"date_of_birth": "1990-01-15",
"social_security_number": "123-45-6789"
}
]
}
```
The response is `{"success": true, "submission_id": "…"}`. Bulk contribution is
also available via [file upload](/api-overview/furnishing/file-upload.md) and
[SFTP](/api-overview/sftp/overview.md); see [Furnishing](/api-overview/furnishing/overview.md)
for the full model.

### KYCCertificateSnapshot (policy configuration only)
These certificate-level fields are used when configuring a
[querying policy](/concepts/governance/querying-policies.md) — e.g. requiring a
certificate no older than 30 days. They are filters over issued certificates,
not data projected into the query response.
