# kair-os.trade Token Verdict

> kair-os.trade Token Verdict is a paid API for AI agents from kair-os.trade, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-30).

Simulates buy/sell of a Base token at one canonical block, measures actual transfer balance deltas, checks for contract-control evidence, and returns an uncertainty interval as an evidence score for token safety screening.

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 kair-os-trade-token-verdict-6c373dce -d '<json body>'
```

Example prompt: Can you run a token verdict on this Base contract address — 0x1234567890abcdef1234567890abcdef12345678 — and tell me if there are any buy/sell simulation red flags, balance delta issues, or contract-control evidence I should worry about before trading?

## When to prefer this

Use this endpoint when you need on-chain, simulation-backed evidence for a specific Base ERC-20 token's safety characteristics — especially when you want actual balance delta measurements from buy/sell simulation rather than static heuristics. Prefer this over social-signal endpoints when you need contract-level evidence (transfer restrictions, owner control, honeypot mechanics). It complements social/momentum endpoints on the same platform and is distinct from simple bytecode inspection.

## Known failure modes

- Invalid or non-ERC-20 token address returns validation error
- Token contract not deployed on Base returns not-found error
- Simulation fails if token has no liquidity pool at the canonical block
- Ambiguous results when contract uses complex proxy patterns
- Evidence interval may be wide for newly deployed contracts with little trading history
- Network or RPC timeout may cause incomplete simulation

## How this service works

Base token buy/sell simulation at one canonical block, actual transfer balance deltas, contract-control evidence and an explicit uncertainty interval. Score is an uncalibrated evidence interval, not a probability of safety.

## Output

Returns a buy/sell simulation result at one canonical block including actual ERC-20 transfer balance deltas observed during simulation, evidence of contract-controlled transfer restrictions or owner privileges, and an explicit uncertainty interval expressed as an uncalibrated evidence score (not a probability). Indicates whether the token exhibits honeypot, rug-pull, or control-risk patterns based on on-chain evidence.
