+``claimPost: creates a new claim in the database using the data provided in the request body. If the request contains the necessary environment variables, it also sends the claim data to a third-party service using an HTTP POST request. Returns the created claim as a JSON response.
+claimGet: retrieves a list of claims from the database, filtered by optional query parameters such as a search term or pagination limits. If a claim ID is provided in the request params, returns the single claim object with that ID. Otherwise, returns an array of claim objects and a count of the total number of claims in the database.
+nodesGet: retrieves a list of nodes from the database, filtered by optional query parameters such as a search term or pagination limits. If a node ID is provided in the request params, returns the single node object with that ID and any edges connected to it. Otherwise, returns an array of node objects and a count of the total number of nodes in the database.
