Implementation Reference

• src/index.ts:1397-1428 (handler)

  Complete implementation of the getSignature tool that retrieves signature details for a specific CID from Pinata IPFS. Includes schema definition (network and cid parameters) and the async handler that makes a GET request to the Pinata API and returns the signature data.

  server.tool(
    "getSignature",
    "Get signature details for a specific CID",
    {
      network: z
        .enum(["public", "private"])
        .default("public")
        .describe("Whether the file is on public or private IPFS"),
      cid: z.string().describe("The CID to get the signature for"),
    },
    async ({ network, cid }) => {
      try {
        const url = `https://api.pinata.cloud/v3/files/${network}/signature/${cid}`;
  
        const response = await fetch(url, {
          method: "GET",
          headers: getHeaders(),
        });
  
        if (!response.ok) {
          throw new Error(
            `Failed to get signature: ${response.status} ${response.statusText}`
          );
        }
  
        const data = await response.json();
        return successResponse(data);
      } catch (error) {
        return errorResponse(error);
      }
    }
  );
