# Sources and acquisition

Sources and acquisition: the 6 calls this system serves, each a route of the API and a tool of the MCP server, at contract 0476e35e6e275db5.

[figure: Sources and acquisition: 6 calls of the contract, by family.]

# Sources and acquisition

The 6 calls below are the whole of this system on the wire: each is one route of the API and one tool of the MCP server, with one typed input, one card as its answer and one refusal shape. Every answer carries its foot: what was read, the population and the control.

## The calls



| tool | route | takes | gives |
|---|---|---|---|
| [si.read.connectors](/reference/tools/si-read-connectors) | [POST /v1/read/connectors](/reference/read/connectors) | a tenant or a brand | every kind of reading and of action, by source, with its state, the identity it needs, its cost and its rights |
| [si.read.coverage](/reference/tools/si-read-coverage) | [POST /v1/read/coverage](/reference/read/coverage) | a cell, or a scope of entities with a window | what has been read, when and how deep, in the three positions |
| [si.act.decide_ask](/reference/tools/si-act-decide_ask) | [POST /v1/act/decide_ask](/reference/act/decide_ask) | the ask, by a user who may | the ask, approved or declined |
| [si.act.install_connector](/reference/tools/si-act-install_connector) | [POST /v1/act/install_connector](/reference/act/install_connector) | the connector, the ways chosen, and the identity for each | an installed connector, ready or not ready with its reason |
| [si.act.raise_need](/reference/tools/si-act-raise_need) | [POST /v1/act/raise_need](/reference/act/raise_need) | a cell's key, the reason and the value | the cell, wanted |
| [si.act.watch](/reference/tools/si-act-watch) | [POST /v1/act/watch](/reference/act/watch) | a public entity | a watched identity, with its monitor armed |



## The bars this system enforces

Every bar is a row of the parameter register: an administrator changes it, and the platform reads it by name at the place of enforcement the row records.

| parameter | family | dimension | enforced at |
|---|---|---|---|
| the plan's limit of delivered leads | receive | leads in a period | F11's second step, which the register calls *withhold, deliver* |
| the budget of a plan | intend | units of a named kind in a period | F2 |
| the ceiling of risk for an ask | intend | a share | F2b |
| the floor of tenants that must share a need | intend | a count of tenants | F1b |
| depth, rate and politeness of a way | source | items in a call, calls in a time | F4, at the call |
| the byte budget of a connector | source | bytes in a day | F4 |
| the rate for one site, which a lease carries | source | calls in a time, for one way of reaching one address as one identity | F4, at the call, in whichever host holds the lease |
| the acquisition system's declared capacity | machinery | windows in flight | F4, when a job leaves the queue |
| the floor of a cell's coverage | intend | a share of the cell's scope of entities | F7 |
| the retry bound of a partition handover | machinery | a count of tries | F7 |
| the term of a demand statement | machinery | a time | the host, which stops reading under a statement whose term has passed |
| the planning beat | machinery | a time | F2 |
| the longest wait of each place | machinery | a time | the reader of that place |
| the good-for time of each kind of fact | machinery | a time | F1b |
| the order of fetching | intend | a ranking by value | F8a |
| the cadence the platform asks of the acquisition system for a source | intend | a time | F3 |
