The list-vendors endpoint returns your full vendor register — feeding GDPR Article 28 transparency, DORA Article 28-30 ICT third-party risk, and ISO 27001 A.5.19 supplier inventory. Use it to drive procurement-side dashboards, due-diligence reports, or to mirror the register into a parent organization’s GRC tool.

Common use cases

Article 28 register export — pull the full register for GDPR DPA submissions
DORA Register of Information (ROI) — feed the ESAs’ XLSX submission format
Concentration risk analysis — pipe the data into a custom analysis (e.g. counting how many critical functions depend on a single hyperscaler)
Procurement integration — sync vendor records bidirectionally with Coupa / Ariba / etc.

Filtering

Common filters:

Query parameter	Values	Use
`criticality`	`critical` / `important` / `standard`	DORA-style criticality slicing
`processesPersonalData`	`true` / `false`	GDPR Art. 28 register subset
`ictService`	`true` / `false`	DORA Art. 28 ICT-vendor subset
`category`	freeform string	Industry / category match
`country`	ISO 3166-1 alpha-2	Filter by country of registration

Combine filters to slice the register narrowly:

# Critical ICT vendors that process personal data
curl "https://api.matproof.com/v1/vendors?criticality=critical&ictService=true&processesPersonalData=true" \
  -H "X-API-Key: ..."

Pagination

Default perPage is 50, max 200. For organizations with hundreds of vendors, paginate with page and stop when meta.page === meta.totalPages.

DPA status

Each vendor record includes dpaStatus: signed / pending / not_required. Filter by dpaStatus=pending to surface vendors still missing DPAs — useful for an end-of-quarter DPA cleanup sweep.

Sub-processors

Sub-processors of each vendor (when collected via the Article 28 questionnaire) are returned in the subProcessors array. Each sub-processor entry includes name, country, and processing-purpose category.

Response shape

The interactive playground below renders the full schema. The fields most often consumed by external systems are:

id, name, country, category
criticality, ictService, processesPersonalData
dpaStatus, dpaSignedAt, dpaUrl
lastReviewedAt, nextReviewDue
subProcessors[] — sub-processor disclosures
transferMechanism — for non-EU vendors handling personal data

For DORA Register of Information submissions, the dedicated Export → DORA ROI action in the Matproof UI produces the structured XLSX format ESAs accept — typically more direct than building it from this API yourself.
