# SVM402 Held-Position Integrity Check

> SVM402 Held-Position Integrity Check is a paid API for AI agents from svm402.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-14).

Checks whether a Solana token you currently hold is still safe, using five tripwires: mint/freeze authority reactivation, honeypot detection, liquidity collapse, and more.

## 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 svm402-held-position-integrity-check-fd7fa673
```

Example prompt: Can you run a held-position integrity check on the Solana token So11111111111111111111111111111111111111112 — I entered when liquidity was about $500,000 USD, so use that as my baseline and tell me if any of the five safety tripwires have fired?

## When to prefer this

Use this endpoint when you need to continuously monitor or spot-check the safety of a Solana token you already hold, especially when you want to compare current on-chain state against your known entry conditions. It is purpose-built for held-position risk — not for pre-entry discovery — and uniquely offers a liquidity-baseline parameter so that collapse is measured relative to your personal entry point rather than an arbitrary threshold. Prefer this over general token analysis endpoints when you specifically want to know if something has changed since you bought in.

## Known failure modes

- Invalid or malformed Solana mint address returns an error response
- Token not found on-chain or not indexed returns empty or error result
- Liquidity baseline not provided may reduce precision of collapse detection
- Jupiter or on-chain data unavailability may cause incomplete analysis
- Transient network issues with Solana RPC can cause timeouts or stale data

## How this service works

Held-position integrity check — is a token you hold STILL clean? Pass your entry-time liquidity as a baseline. Five tripwires: mint/freeze authority reactivated, honeypot, liquidity collapse (<25% of…

## Output

Returns a structured safety report for the held Solana token, including pass/fail status for each of five tripwires: mint authority reactivation, freeze authority reactivation, honeypot classification, liquidity collapse (below 25% of the baseline provided), and any additional integrity signals. Each tripwire indicates whether the token's safety profile has deteriorated since entry.
