Choose a public 561 Group service
Start with the result you want. Causeway Services connects public material and capabilities to readers, customers and software agents while each product retains its own terms and authority.
Find the useful entrance
| If you want to… | Open | Next action |
|---|---|---|
| Understand the scope of a market observation | Market | Inspect the dated source, population, unit and coverage; follow the original source |
| Find or compare an original offer | Bazaar | Search, open details and use the labeled comparison form |
| Find a book and its edition | Shop | Read the product page, format, price and availability |
| Inspect original machine-service terms | Merchant catalog | Read the original resource, method and payment requirement |
| Understand the research, software or operation behind a service | Science, Engineering, Operations | Choose the relevant resource guide without needing to learn the internal organization first |
A listed or coming-soon item is not a promise that a purchase can be completed now. Original publishers supply the terms, availability and rights. A comparison explains the selected terms and any incompatibility; it does not itself authorize payment or choose a winner.
For software agents
Start with Bazaar discovery for search, detail and comparison endpoints. Its MCP endpoint is https://bazaar.561.group/mcp, using the declared POST protocol and tool schemas. Market discovery describes the separate observation tools at https://market.561.group/markets/mcp.
Shop catalog JSON carries original product data. The merchant's existing catalog and discovery document describe its original service and payment boundary. Reading a catalog or calling a read-only discovery tool does not complete a paid operation.
