Dev Preflight

Check whether a shell command is runnable before you (or an agent) run it — a pre-execution gate.

Overview

Check whether a shell command is runnable before you (or an agent) run it — a pre-execution gate. POST { command } with a command that targets the network (curl, wget, httpie, or anything carrying a URL). Parses out the HTTP method, target URL, and headers, then returns a structured verdict: verdict ('runnable' or 'invalid'), a runnable boolean, and a checks breakdown (hasTarget, urlValid, schemeOk, hostPresent, methodValid, privateTarget). By default the check is STATIC and deterministic — no network call — answering 'is there a well-formed http(s) target and a valid method?' (a command with no URL is invalid). Pass probe=true to also run a guarded HEAD request against the target and report dnsResolves, reachable, tlsValid, and httpStatus — answering 'would this actually connect right now?'. Private/loopback/reserved targets are refused (SSRF-safe). Built for gating agent-generated commands and CI pipelines.

How to call it

Requests are paid per call over the x402 protocol. Call the endpoint, receive a 402 Payment Required quote, then repeat the request with the signed payment header. The SDKs do both steps for you.

# 1. Ask for a quote
curl -i -X POST https://api.jarvisclaw.ai/v1/marketplace/api/dev-preflight \
  -H 'Content-Type: application/json' \
  -d '{}'

# 2. Pay it (the SDK signs and retries for you)
curl -X POST https://api.jarvisclaw.ai/v1/marketplace/api/dev-preflight \
  -H 'Content-Type: application/json' \
  -H 'X-PAYMENT: <signed-payload>' \
  -d '{}'
