# Agent Endpoint Trust & Prompt-Injection Scan

> Agent Endpoint Trust & Prompt-Injection Scan is a paid API for AI agents from api.the402.ai, paid per call via x402, $0.032/call, status unknown (last checked 2026-09-16).

Scans an AI agent endpoint for trustworthiness and prompt-injection vulnerabilities, returning a job ID and status for async result retrieval.

## Facts

- Endpoint: POST https://api.the402.ai/v1/services/svc_bc1ed7efb21349f1/purchase
- Price: $0.032/call
- Payment: x402

- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_DB6MgSNeJkGtwCGgrAO-N

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability agent-endpoint-trust-prompt-injection-scan-08291af2 -d '<json body>'
```

Example prompt: Can you run a trust and prompt-injection scan on this agent endpoint — https://someagentservice.example.com/api/chat — and flag any vulnerabilities or manipulation risks before I integrate it into my workflow?

## When to prefer this

Use this endpoint when an AI agent needs to vet a third-party agent service for prompt-injection vulnerabilities or trust signals before integrating it into an automated workflow. Prefer this over manual review when operating at scale or when the endpoint's provenance is unknown. Particularly valuable before purchasing or chaining other paid agent services discovered on marketplaces like the402.ai.

## Known failure modes

- Payment failure or insufficient USDC balance — scan is not initiated
- Invalid or unreachable target endpoint URL — job may fail or return error status
- Malformed request body — 4xx error returned
- Scan job times out on backend — status may remain stuck
- Target endpoint blocks the scan probe — incomplete results

## How this service works

Purchase: Agent Endpoint Trust & Prompt-Injection Scan

## Output

Returns a JSON object with a job_id (unique identifier for the async scan job), a status string indicating whether the scan is queued or in progress, and a thread_id for tracking the analysis thread. The agent should poll the job status endpoint using job_id to retrieve final results.
