> HostDeFi Token Risk Grade API is a paid API for AI agents from hostdefi.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-09).

Returns a letter-grade risk assessment and risk score for a token by contract address across Solana and EVM chains

## 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 hostdefi-token-risk-grade-api-44cdbe0d
```

Example prompt: Can you check the risk grade for the BONK token on Solana — the mint address is DezXAZ8z7PnrnRJjz3wXBoRgixCa6xjnB7YaB1pPB263 — and tell me if it's safe to swap?

## When to prefer this

Choose this endpoint when you need a quick, structured risk grade for a specific token before executing a swap or making an investment decision across Solana or EVM chains. It is particularly useful for agents that need a single authoritative risk signal (letter grade + score) rather than raw on-chain data, and works across 8 chains including Solana, Ethereum, Base, Arbitrum, Optimism, BSC, Polygon, and Avalanche. Prefer this over manual on-chain analysis when you need a fast, actionable risk verdict at low cost ($0.01 per call).

## Known failure modes

- Invalid or unrecognized chain ID returns an error
- Malformed contract address (wrong format for chain type) returns validation error
- Token contract not found on specified chain returns not-found error
- Payment failure (x402 micropayment not processed) returns 402 Payment Required
- Rate limiting or network issues may return 5xx errors

## How this service works

HostDeFi is a non-custodial Solana DEX. Best-route swaps through Jupiter, EVM trading across 7 chains, native bridging, and live token risk grades. No KYC, no accounts, no custody.

## Output

A JSON object containing: an overall letter risk grade (e.g. A, B, C), a numeric risk score (0-100), a human-readable verdict string, the token's chain and symbol, and a signals object with specific risk indicators that contributed to the grade.
