# Orion CINT Revenue Safety — Approval Spender Check

> Orion CINT Revenue Safety — Approval Spender Check is a paid API for AI agents from orionkr.xyz, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-15).

Checks whether a Base blockchain address, token, or contract is safe to approve as a spender before an agent executes a swap or token approval, returning a PASS/WAIT/FAIL verdict with a risk score and blocking flags.

## 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 orion-cint-revenue-safety-approval-spender-check-388dff8d
```

Example prompt: Before my agent approves the spender contract at 0x4497464A3eAFAd8153cFd7F4681966a472f1bAb9 on Base to swap 500 USDC, run an Orion approval-spender safety check and tell me the risk score and whether it's safe to proceed.

## When to prefer this

Use this endpoint as the first gate before any token approval or swap on Base, especially in autonomous agent flows where a human is not manually reviewing each transaction. It is specifically designed for Virtuals and x402 agent pipelines and integrates with the Orion stateful safety chain (followed by /v1/base/transaction-safety and /v1/base/before-signing). Prefer this over generic on-chain lookups when you need a structured PASS/WAIT/FAIL verdict with a TTL, blocking flags, and a guided next-step recommendation.

## Known failure modes

- Address not on Base — returns error or unexpected verdict if a non-Base address is supplied
- Missing required address param — API may return a 400 or empty result
- Contract not indexed — unknown or newly deployed contracts may return a high risk score by default due to lack of history
- Stale verdict — if TTL has expired, the result may no longer reflect current chain state
- Rate limit or payment failure — x402 payment not processed correctly results in 402 response

## How this service works

Orion CINT Revenue Safety is a Virtuals and x402 agent payment safety layer with live CINT RHC Pulse holder tiers, current USDC creator-payout evidence, historical cbBTC context, provider trust checks, transaction safety, and guarded swap planning.

## Output

Returns a JSON object with a boolean success flag, a verdict string (PASS, WAIT, or FAIL), a numeric risk_score (0–100), an array of blocking_flags describing detected issues, a verdict_ttl_seconds indicating how long the result is valid, and a required_next_call path pointing to the recommended follow-up endpoint (e.g. /v1/base/transaction-safety or /v1/base/before-signing).
