Supply Chain API is one of 9 APIs that [IAB Tech Lab](https://apis.io/providers/iab-tech-lab/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Supply Chain, ads.txt, sellers.json, Transparency, and Compliance. The published artifact set on APIs.io includes API documentation and pricing.

IAB Tech Lab's hosted, subscription API for aggregated supply-chain data: crawled and validated ads.txt, app-ads.txt and sellers.json files, plus the Transparency Center's compliance and identifier registries (OM SDK and podcast compliance, MSPA signatory IDs, SKAdNetwork IDs, GPP data). Access is provisioned through the Tech Lab Tools Portal (tools.iabtechlab.com, free login) at /transparencycenter/apiAccess/all; the backing host api.iabtechlab.com (alias coreapi.iabtechlab.com) identifies itself as 'IAB Tech Lab Core API' and answers /health, but /docs, /docs/oauth and /openapi.json all 302 to /login, so the contract is gated behind a subscription. Basic tier is $2,500/yr for members and $4,500/yr for non-members; API+ adds $2,500/yr.
