# Everything the project's agents call

`GET /api/v1/dependencies`

## Request

- Base URL: `https://app.lastping.dev`
- URL: `https://app.lastping.dev/api/v1/dependencies`
- Auth: API key in header `X-Api-Key`

Every outgoing dependency in the project over the range, summed over
every agent and monitor ("everything that calls postgres"), with the
agents that call each one. Most calls first, at most 50; `more`
counts the rest. Filter to one kind with `kind`.

## Query parameters

- `range` '24h' | '7d' | '30d'
- `kind` 'model' | 'tool' | 'http' | 'database' | 'queue' | 'rpc' | 'agent'

## Response `200`

The project's dependencies.

- FleetDependencies: The body of `GET /api/v1/dependencies`.
  - `range` '24h' | '7d' | '30d', required
  - `dependencies` FleetDependency[], required: At most 50, most calls first.
    - `kind` 'model' | 'tool' | 'http' | 'database' | 'queue' | 'rpc' | 'agent', required
    - `name` string, required: The display name: `postgresql app`, `api.github.com`, `anthropic claude-sonnet-4-5`. Never a URL and never a path.
    - `direction` 'out' | 'in', required: `out` for something the agent calls, `in` for a caller of the agent.
    - `calls` integer, required
    - `errors` integer, required: Calls whose span reported an error status.
    - `error_rate` number, double, required: `errors / calls`, from 0 to 1; 0 when there were no calls.
    - `p50_ms` integer, required
    - `p95_ms` integer, required
    - `p95_is_floor` boolean, required: True when the 95th percentile call was slower than the last bucket (60 s), so `p95_ms` is a floor.
    - `tokens_in` integer, nullable, required: Input tokens, including cache reads (the OpenTelemetry rule). Null for every kind but `model`.
    - `tokens_out` integer, nullable, required: Output tokens. Null for every kind but `model`.
    - `cost_usd` string, nullable, required: Cost in US dollars as decimal text. Null for every kind but `model`, and for a model no call reported or could be priced.
    - `cost_source` string, required: What `cost_usd` is made of. A plain string, not an enum, so a new value never breaks a client: `client` when every priced call's cost was reported by the client (the exporter's own figure, or Claude Code's per-call cost), `estimated` when LastPing priced every call at API list prices, `mixed` when the sum holds both, empty when `cost_usd` is null.
    - `series` DependencySeriesPoint[], required: One point per UTC day of the range, oldest first, including days with no calls, for a row sparkline.
      - `day` string, date, required
      - `calls` integer, required
      - `errors` integer, required
    - `agents` FleetDependencyAgent[], required
      - `id` string, uuid, required
      - `name` string, required
      - `calls` integer, required
  - `more` integer, required: How many more dependencies the range holds beyond the ones returned.

## Other responses

- `400`: An invalid `range` or `kind` (`INVALID_FILTER`).
- `401`: Missing or invalid API key.
