## 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 synthora-crypto-due-diligence-6a7d480d -d '<json body>'
```

Example prompt: Before we approve the token spend, run a full SYNTHORA crypto due-diligence check on the contract 0x8589427373D6753490842286A5539b81bfD7977 on Ethereum and tell me if it's SAFE, CAUTION, or DANGER.

## When to prefer this

Use this endpoint when an AI agent needs a single comprehensive risk decision on an EVM token or wallet before taking an action (trading, approving, paying, bridging) and wants to avoid orchestrating multiple separate API calls to GoPlus, Chainalysis, and TRM independently. Ideal for autonomous agents that need a deterministic, signed, pay-per-call verdict with no API key management overhead. Prefer over individual oracle calls when latency and cost efficiency matter and when partial-degradation guarantees are important.

## Known failure modes

- Invalid or malformed EVM address returns an error and no charge
- Unsupported chain identifier returns a validation error
- All downstream oracles (GoPlus, Chainalysis, TRM) fail simultaneously — call is not charged per partial-degradation policy
- Network timeout from upstream providers may return partial results
- Contract address on wrong chain returns misleading or empty on-chain data

## How this service works

One-call crypto due-diligence for AI agents: give it any EVM token contract or wallet address and get a full risk dossier plus a single verdict (SAFE / CAUTION / DANGER). For a TOKEN it checks honeypot, buy/sell tax, mint/pause/blacklist owner privileges, proxy upgradeability and ownership renouncement (GoPlus + on-chain). For a WALLET it screens OFAC and EU sanctions via Chainalysis and TRM oracles plus an inline OFAC SDN list, and flags phishing, mixer and blacklist exposure and native balance. Composes SYNTHORA's whole risk stack in ONE paid call instead of four, so an autonomous agent can vet a counterparty, token, airdrop, contract or payee before it trades, bridges, signs an approval or pays. Auto-detects token vs wallet. Keyless, deterministic, Ed25519-signed, partial-degradation (never charges when all checks fail). 0.01 USDC on Base. SYNTHORA.

## Output

A JSON dossier containing a top-level SAFE/CAUTION/DANGER verdict, the auto-detected subject type (token or wallet), and a breakdown of all individual checks: for tokens — honeypot status, buy/sell tax, mint/pause/blacklist privileges, proxy upgradeability, ownership renouncement; for wallets — OFAC/EU sanctions hits, phishing/mixer/blacklist flags, native balance. Also includes a count of passing checks and provenance metadata. The call is not charged if all checks fail.
