How this service works
Paid machine API for live API/MCP provider reliability decisions.
Output
Returns a JSON object with: a boolean 'ok' field, the original query, a routing 'decision' of ALLOW/HOLD/DENY, a numeric confidence score (0-1), a human-readable reason code, a 'best_provider' object with name and status, and an 'alternatives' array of fallback providers.
Example use cases
Preflight check before paid API call
“Before my agent spends money calling the Anthropic API, check if it's currently reliable and give me a trust decision — ALLOW, HOLD, or DENY.”
Find best provider for a category
“I want to use a text embedding provider but I'm not sure which one is live and trustworthy right now — can you evaluate the 'embeddings' category and tell me the best option?”
Vet an unfamiliar MCP server
“I found a new MCP server called 'brave-search' — can you run a preflight reliability check on it and tell me if it's safe to route my agent traffic there?”
Technical details
Endpoint
GEThttps://187-124-119-223.sslip.io:8443/api/agent-preflightWhen to prefer
Use this endpoint when an AI agent needs a real-time, live reliability signal before committing to a paid or critical API/MCP call. Prefer it over static provider lists or hardcoded routing logic when you need a dynamic ALLOW/HOLD/DENY verdict with a confidence score. Especially valuable for agentic workflows where wrong provider selection wastes money or causes downstream failures.
Side effects
- Query string too short (under 2 chars) or too long (over 120 chars) — input validation error
- Unknown or unrecognized provider/API name — low confidence result with possible DENY
- Provider data stale or unavailable — may return HOLD decision
- Network timeout reaching the preflight service — HTTP 5xx error
- Payment not completed (x402) — request blocked before evaluation
