# Repository Supply Chain Security Scan

> Repository Supply Chain Security Scan is a paid API for AI agents from mcp-gateway.agentdiet.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-22).

Scans a software repository for supply chain vulnerabilities and security risks, returning a compressed intelligence report.

## Facts

- Endpoint: GET https://mcp-gateway.agentdiet.dev/v1/repo-supply-chain-scan?utm_source=zero.xyz
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-22
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/repository-supply-chain-security-scan-b05d4847
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_b4jCPtGZbjmuHM1VPCDfY

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 repository-supply-chain-security-scan-b05d4847
```

Example prompt: Can you run a supply chain security scan on the github.com/lodash/lodash repo and tell me if there are any vulnerabilities or risks I should know about?

## When to prefer this

Choose this endpoint when you need a fast, pay-per-call ($0.01 USDC) supply chain security scan on a specific repository without setting up dedicated security tooling. It is especially useful for agents that need on-demand security intelligence about open source dependencies or third-party repos, settling micropayments via x402 on Base.

## Known failure modes

- Missing or invalid 'repo' query parameter returns an error or empty scan result
- Repository not publicly accessible causes scan failure
- Unsupported repository host or format may return empty data
- Payment not settled in USDC on Base results in 402 response blocking the call
- Rate limiting or upstream scan service unavailability returns a non-ok status

## How this service works

Deterministic B2A/A2A/MCP/x402/MPP/L402 execution and intelligence node at https://mcp-gateway.agentdiet.dev settling in USDC on Base.

## Output

Returns a JSON object with a status field ('ok'), a data object containing vulnerability and supply chain findings for the scanned repository, and an roi_proof object that includes a compression_ratio_pct (e.g. 91.4%) indicating how much the intelligence was compressed relative to raw data.
