# Solidus Trade Verdict — SPL Pre-Trade Safety Decision

> Solidus Trade Verdict — SPL Pre-Trade Safety Decision is a paid API for AI agents from solidus-x402.fly.dev, paid per call via x402, $0.25/call, status down (last checked 2026-09-15).

Returns a composite PROCEED|PROCEED_WITH_CAPS|ABORT verdict for a Solana SPL token trade, bundling rug check, honeypot sell simulation, fee weather, and optional wallet drainer scan into one signed decision with a position-size cap and 90-second TTL.

## 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 solidus-trade-verdict-spl-pre-trade-safety-decision-f8e86f1f
```

Example prompt: Before I swap into this Solana token — mint EPjFWdd5uFddCFQnFn4B6xHnkZHjCKfDJDCUfkfVEdFj — run the full trade verdict check and tell me if it's safe to proceed and what the max safe position size is.

## When to prefer this

Use this endpoint when you need a single authoritative go/no-go decision before executing an SPL token trade and want to avoid paying for rug check, honeypot simulation, and fee weather separately. It saves 47% over calling each sub-check individually, applies worst-signal logic so no bad signal is masked, and provides a signed, time-bounded verdict suitable for automated trading bot gates. Prefer it over individual sibling endpoints (mint_hygiene, sell_sim) when you need a composite, actionable decision rather than raw signal data.

## Known failure modes

- Missing or invalid mint pubkey returns an error — base58 format required
- Degraded signal from one or more sub-checks may result in no charge but still returns a partial verdict
- 90-second TTL means stale verdicts should not be reused for subsequent trades
- Optional wallet drainer scan only runs when &wallet= is supplied; omitting it leaves that risk leg unchecked
- Service may be unavailable if the underlying fly.dev host is down

## How this service works

Pre-trade VERDICT — one call, one decision — Should this exact SPL trade go through? ONE $0.25 call composes rug check ($0.10) + honeypot sell-sim ($0.15) + fee weather (+ wallet drainer-scan with &wallet=) into a signed PROCEED|PROCEED_WITH_CAPS|ABORT verdict with max_safe_size_usd (exit-liquidity position cap) and a 90s TTL. 47% off a-la-carte; worst signal wins; never charged on a degraded answer.

## Output

A signed verdict object containing one of three decisions — PROCEED, PROCEED_WITH_CAPS, or ABORT — along with a max_safe_size_usd field indicating the maximum recommended position size given exit liquidity, a TTL of 90 seconds, and the worst-signal composite result from rug check, honeypot sell simulation, fee weather analysis, and optional wallet drainer scan. No charge is applied if the answer is degraded.
