  The main handler function that performs the actual tool execution: calls Apollo API /job_postings/search endpoint with provided arguments, processes up to 20 job postings, and returns formatted text results.
  private async searchJobPostings(args: any) { const response = await this.axiosInstance.post("/job_postings/search", args); const jobPostings = response.data.job_postings || []; let result = `Job Postings Found: ${jobPostings.length}\n\n`; jobPostings.slice(0, 20).forEach((job: any, index: number) => { result += `${index + 1}. ${job.title}\n`; result += ` Company: ${job.organization?.name || "N/A"}\n`; result += ` Location: ${job.city || "N/A"}\n`; result += ` Posted: ${job.posted_at ? new Date(job.posted_at).toLocaleDateString() : "N/A"}\n`; result += ` URL: ${job.url || "N/A"}\n\n`; }); return { content: [ { type: "text", text: result, }, ], }; }
