OpenAPI Specification

placementapi-com-catalogue-api-openapi.yml Raw ↑
openapi: 3.2.0
info:
  title: Placement Catalogue API
  version: 1.0.0
  description: 'Normalised backlink placement inventory, deduplicated across multiple suppliers, with independent verification, held quotes, ordering, content handling and post-placement outcome tracking. Every price is the buyer price in credits (1 credit = 1 US cent), already normalised from supplier currencies, so the figure you plan with is the figure you are charged. Supplier identity is never exposed.


    Authenticate with a `pk_live_…` API key as a Bearer token. Keys carry scopes: `read` (catalogue, quotes, account reads) and `order` (anything that moves money). An MCP server exposing the same operations as tools is available at https://api.placementapi.com/mcp with the same Bearer key; the tools call these endpoints, so pricing and verification are identical either way. Unknown query parameters and brief fields are refused with 400 rather than ignored.'
