USAGE PATTERNS · LETSPING SDK

Real guardrails.
For real agent failures.

Letsping isn't just for debugging. It's a governance layer. Explore how teams use await ask() to secure agentic workflows across their critical infrastructure.

Wire Transfer Circuit Breaker

StripeFraud Prevention

Agent exceeds a cost threshold mid-run — the transfer freezes for human review before any funds move.

agent_logic.ts
import { LetsPing } from "@letsping/sdk";
import { ai } from "vercel-ai-sdk";
 
const lp = new LetsPing();
 
// 1. Wrap your sensitive stripe method
const secureTransfer = lp.tool("treasury-bot", "stripe:transfer", "critical");
 
// 2. Pass it to your agent framework as normal
const agent = ai({
  tools: [secureTransfer, getBalance, ...otherTools]
});
 
// If the agent attempts a massive transfer that deviates from the baseline,
// LetsPing detects the anomaly and triggers the approval flow.
// The transfer runs automatically using your patched context.

Runaway Fine-Tune Cost Guard

Cost ControlLLM Budget

Detect an agent stuck in an expensive retry loop before it creates the sixth $12/job fine-tuning run.

agent_logic.ts
import { LetsPing } from "@letsping/sdk";
 
const lp = new LetsPing();
const session = await getSession(agentId);
 
if (session.totalCost > session.budget) {
  const decision = await lp.ask({
    service: "training-bot",
    action: "llm:fine_tune_create",
    priority: "high",
    payload: {
      model: "claude-3-5-sonnet",
      reason: "Previous job failed, retrying…",
      estimatedCost: "$14.00",
    }
  });
 
  if (decision.status === "REJECTED") {
    return { status: "aborted", reason: "budget_exceeded" };
  }
}
