# Register a custom disk provider

`POST /marketplace/providers/disks`

## Request

- Base URL: `https://pricing.baselinehq.cloud`
- URL: `https://pricing.baselinehq.cloud/marketplace/providers/disks`
- Auth: one of:
  - API key in header `X-API-Key`
  - API key in header `Authorization`
- TypeScript: <https://skmtc.dev/baselinehq/apis/costgraph-pricing-api/docs/marketplace/providers/disks/post.ts> (a function with typed inputs; its response is checked against the schema)

> **Deprecated.**

Register your own storage rates, priced per GB hour with optional IOPS and throughput components and the capacity band they apply to.
An entry is upserted on its natural key (provider, service, region, availability zone, disk type, usage type and period billing hours), so re-posting with a new cost keeps its id; changing a key field mints a new one.
Capacity, IOPS and throughput bands are not part of that key, so a second band for the same disk type replaces the first: give each band its own usage type.
The returned id is what you attach with the `costgraph.ai/pricing-id.storage` label or tag.
Superseded by POST /v1/marketplace/disks, which returns RFC 9457 problem responses on failure.
