# Resources

> Where to find each LevelFour API method: one page per resource, with its parameters and the call in each SDK that carries it.

Source: https://docs.levelfour.ai/resources


Each page below covers one resource: the methods that read or change it, the parameters they take, and the call in each SDK that carries it, with plain HTTP where an SDK does not.

## The resources

| Resource                                      | What it covers                                                                                                             |
| --------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------- |
| [Recommendations](/resources/recommendations) | Pending savings opportunities: idle resources, rightsizing, reserved instances                                             |
| [Savings](/resources/savings)                 | Realized savings from implemented recommendations                                                                          |
| [Costs](/resources/costs)                     | Current cloud costs with breakdowns by service, account, and time period                                                   |
| [Providers](/resources/providers)             | Provider-scoped reads for recommendations, savings and costs on AWS, GCP, Azure and Kubernetes                             |
| [Cost Alerts](/resources/cost-alerts)         | Alerts that watch an account, a saved cost view or your commitments: create, change, pause, delete, and what each one said |
| [Commitments](/resources/commitments)         | Reserved Instances and Savings Plans: inventory, utilization, coverage, effective savings rate and renewal pricing         |
| [Google Cloud](/resources/google-cloud)       | Google Cloud reads beyond the bill: data availability, inventory, idle resources, labels, utilization, budgets and access  |
| [Accounts](/resources/accounts)               | Connected cloud accounts, what LevelFour can do in each, your modules, and connected work tools                            |

> **Warning**

> Recommendations and Savings are not two views of one number: one counts opportunity nobody has applied, the other counts what was applied and measured. A figure that adds both double counts.

## Next

* [SDKs](/sdks) is the client these methods hang off: constructor options, minimum versions and the sub-client names
* [Pagination](/pagination) has the envelope every list response carries, and the iterators that walk it for you
* [Error handling](/error-handling) has which status raises which class in each SDK, and what the SDKs retry before you see it
* [Webhooks](/webhooks) is registering an endpoint and verifying the signature before you act on the payload
* [API reference](/api-reference) is the generated REST reference for the endpoints behind every method here
