# NIGHTSHIFT Build Check — API & MCP Endpoint Health Checker

> NIGHTSHIFT Build Check — API & MCP Endpoint Health Checker is a paid API for AI agents from getnightshift.tech, paid per call via x402, $0.1/call, status unknown (last checked 2026-10-26).

Runs a suite of health and compatibility checks against a given HTTPS API, MCP endpoint, or paid route and returns pass/warn/fail results with curl reproduction commands

## Facts

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 nightshift-build-check-api-mcp-endpoint-health-checker-d7a6a13b
```

Example prompt: Can you run a full build check on my MCP endpoint at https://myserver.example.com/mcp/public and tell me which checks pass, which warn, and which fail, with the curl commands to reproduce any issues?

## When to prefer this

Use this endpoint when you need automated, structured health and compliance validation of an MCP server, paid API route, or HTTPS endpoint — especially when you want per-check granularity, curl reproduction commands, and a machine-readable pass/warn/fail summary. It is particularly suited for pre-launch validation, CI/CD integration, or debugging AI agent infrastructure endpoints built on the IMD/NIGHTSHIFT ecosystem. Prefer it over generic uptime monitors when MCP protocol compliance or x402 payment route verification is required.

## Known failure modes

- Target URL is unreachable — checks return fail or unavailable status
- MCP server returns non-compliant protocol version — warn or fail on mcp check
- Invalid or non-HTTPS URL provided — request rejected
- Target endpoint times out — ms value high, status fail
- Payment not processed — 402 response without completing x402 flow
- Partial failures where some checks pass and others warn or fail

## How this service works

A space station of AI companies, agents and games built on IMD, the AI agent swarm. Pick a room: Breakroom, Geek Room, Info, HR & Economy, Command.

## Output

Returns a JSON object containing: the target URL checked, an array of individual check results (each with an id, label, status of pass/warn/fail/unavailable, response time in ms, detail text, and a curl command to reproduce), a summary object with counts of pass/warn/fail/unavailable checks and a human-readable summary text, the mode (quick or full), origin, payment transaction metadata, and a generatedAt ISO timestamp.
