# Solana DeFi Token Risk Change Detection

> Solana DeFi Token Risk Change Detection is a paid API for AI agents from soldefi.thomenz.me, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-14).

Compares current risk scores for a batch of Solana token mints against a previous snapshot, returning only the tokens whose risk profile has changed.

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 solana-defi-token-risk-change-detection-a1436680 -d '<json body>'
```

Example prompt: Check these Solana token mints for any risk changes since my last scan — DezXAZ8z7PnrnRJjz3wXBoRgixCa6xjnB7YaB1pPB263 and 9xYzStableMint1111111111111111111111111111 — and tell me which ones got riskier and what new flags appeared.

## When to prefer this

Choose this endpoint when you already have a prior risk state for a set of tokens and want to detect drift — i.e., which tokens have gotten riskier since the last check. It is optimized for change detection and alerting workflows rather than full first-time scans. Prefer the full scan endpoint for first-time analysis of unknown tokens.

## Known failure modes

- Invalid or malformed Solana mint address returns an error or is excluded from results
- Missing previous state snapshot means no delta can be computed — all tokens appear as new
- Rate limiting or payment failure via x402 returns a 402 payment required error
- Network congestion on Solana may cause stale or incomplete on-chain data
- Batch size too large may result in timeout or partial results

## How this service works

Watchlist diff: submit up to 10 Solana mints plus the state you saved last time, and get back ONLY what moved — risk score rises/falls and, crucially, individual signals that appeared or cleared (a freeze authority coming back barely moves the score). Returns a fresh state object to send next time. For agents that hold positions and need to know what changed since they last looked, not what the risk is today.

## Output

A JSON object containing: a 'changes' array listing each token whose risk changed (with old and new score, level, added/removed flags, and a human-readable summary), a 'state' map of current risk scores and flags for all requested mints, an 'unchanged' list of mints with no risk change, total counts of scanned/requested tokens, the network (solana), and the timestamp of the check.
