# 1gateway Solana Token Risk Screener

> 1gateway Solana Token Risk Screener is a paid API for AI agents from 1gateway.dev, paid per call via x402, $0.009/call, status unknown (last checked 2026-10-29).

Analyzes a Solana token mint address for on-chain risk signals including authority renunciation, holder concentration, and rule-based red flags before buying, accepting, or listing.

## 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 1gateway-solana-token-risk-screener-a5eae88c
```

Example prompt: Before I swap into this token, run a risk check on Solana mint EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v — I want to know the risk level, any dangerous authority flags, and how concentrated the top holders are.

## When to prefer this

Use this endpoint when an AI agent or application needs a fast, structured, rule-based risk assessment of a Solana token before any financial action (buy, accept, list). It is particularly well-suited for pre-trade screening pipelines, marketplace listing workflows, and DeFi agent guardrails where you need explicit signal evidence (not just a score) to explain decisions. Prefer this over generic token info APIs when you specifically need authority renunciation status, transfer hook/fee flags, and holder concentration in a single normalized response.

## Known failure modes

- 400 Bad Request — invalid base58 format or missing mint parameter
- 422 Unprocessable Entity — address is valid base58 but is not a token mint (not charged)
- Network or RPC unavailability causing delayed or failed on-chain data fetch
- Token with very low liquidity may return incomplete concentration data
- Unknown or newly created mints may lack symbol or metadata

## How this service works

Use when an agent is about to buy, accept or list a Solana token. Input: mint. Output: JSON riskLevel and rule-based signals with evidence (mint or freeze authority not renounced, permanent delegate, transfer hook, transfer fee, default-frozen accounts, mutable metadata), top-10 holder concentration with owners. Curated issuer stablecoins are marked as expected controls. Not an audit. Example: ?mint=EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v

## Output

Returns a JSON object with: a riskLevel string (e.g. low/medium/high), an array of rule-based signals each with an id, severity, detail, and evidence fields (showing specific authority addresses, basis points for fees, etc.), a concentration object with top-10 holder percentages and account owners, a knownIssuer object if the token is a curated stablecoin, and metadata including chain, cluster, slot, program, and symbol.
