AgentShield for JavaScript

Monitor LLM costs in your JavaScript or Node.js app with a single fetch() call. No SDK, no proxy, no setup.

Quick setup

// Works with any JS environment — Node.js, Deno, Bun, Vercel Edge

async function trackAgentCall(agentName, model, usage) {
  await fetch('https://api.agentshield.one/v1/track', {
    method: 'POST',
    headers: {
      'Authorization': 'Bearer ags_live_xxxxx',
      'Content-Type': 'application/json'
    },
    body: JSON.stringify({
      agent: agentName,
      model: model,
      input_tokens: usage.prompt_tokens,
      output_tokens: usage.completion_tokens
    })
  })
}

// Example with OpenAI SDK:
const completion = await openai.chat.completions.create({
  model: 'gpt-4o',
  messages: [{ role: 'user', content: prompt }]
})

await trackAgentCall('my-agent', 'gpt-4o', completion.usage)
// Per-agent costs now visible in your dashboard.
