# Orion Base Transaction Safety Check

> Orion Base Transaction Safety Check is a paid API for AI agents from orionkr.xyz, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-14).

Pre-execution safety gate for Base memecoin transactions that returns a SAFE_TO_SIGN, RECHECK, or DO_NOT_EXECUTE verdict with risk score, flags, and verification status

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 orionkr-xyz-6ee298c9
```

Example prompt: Before I sign and broadcast this Base memecoin swap, run an Orion transaction safety check on the calldata and route — I need to know if it's SAFE_TO_SIGN or if there are honeypot signs, fake liquidity, or dangerous approvals I should worry about.

## When to prefer this

Use this endpoint immediately before signing or broadcasting any Base memecoin transaction when operating an autonomous trading agent that needs an ultra-low-cost ($0.005 USDC) safety gate. Prefer it over generic token scanners when you need calldata-aware context (approval danger, route risk, slippage) rather than just token-level metadata, and when you need a binary execution decision (SAFE_TO_SIGN / RECHECK / DO_NOT_EXECUTE) integrated into an agentic trade loop.

## Known failure modes

- Missing or malformed transaction calldata returns a 400 error
- Payment not received or insufficient USDC balance blocks the call with a 402
- Unknown or unsupported token/contract address may return unverified with incomplete flags
- Network congestion on Base may delay on-chain data freshness
- False negatives possible for novel rug patterns not yet in detection heuristics

## How this service works

Ultra-low-cost transaction safety check for Base memecoin agents. Use immediately before transaction execution to decide SAFE_TO_SIGN, RECHECK, or DO_NOT_EXECUTE based on route risk, calldata context, approval danger, honeypot signs, sell-tax danger, fake liquidity, and slippage risk.

## Output

A JSON object with a riskLevel (LOW/MEDIUM/HIGH), a numeric riskScore (0-100), a verified boolean, and a flags array listing specific detected risks such as honeypot indicators, fake liquidity, excessive sell tax, dangerous approvals, or high slippage — enabling the agent to decide SAFE_TO_SIGN, RECHECK, or DO_NOT_EXECUTE.
