# PoolProof Known Issues Research Notes

> PoolProof Known Issues Research Notes is a paid API for AI agents from poolproof.qalibr.ru:7443, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-15).

Returns curated research flags on DeFi assets, protocols, chains, or roles covering hidden risks that price feeds and TVL metrics won't reveal, such as dead redemption bridges, ticker collisions, ended points programmes, and closed marketplaces.

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 poolproof-known-issues-research-notes-cdfb4a7a -d '<json body>'
```

Example prompt: Do you have any research flags on the asset or protocol 'stETH' — specifically things like dead redemption bridges, ticker collisions, ended points programmes, or capital gates that a price feed wouldn't tell me?

## When to prefer this

Choose this endpoint when you need qualitative, curated research intelligence about a DeFi asset, protocol, chain, or role that quantitative data sources like price feeds, TVL dashboards, or on-chain analytics cannot surface — specifically for dead bridges, ticker symbol conflicts, discontinued incentive programmes, undocumented capital restrictions, or known measurement failures. Prefer this over generic on-chain data tools when you suspect hidden operational or structural risks.

## Known failure modes

- Unknown or uninvestigated asset returns empty flags array — this does not mean the asset is safe
- Ambiguous asset/protocol names may match unintended entries or return no results
- Input schema may require specific identifier formats not documented in schema stub
- Service unavailability at non-standard port 7443 may cause connection errors
- $0.02 USDC x402 payment failure will block the request

## How this service works

Do we hold a research note on this asset, protocol, chain or role that no price feed or TVL number will tell you: dead redemption bridges, ticker collisions, ended points programmes, closed marketplaces, capital gates

## Output

Returns a JSON object with an 'ok' boolean, a 'verdict' string summarising the overall assessment, an array of 'flags' each containing a code and message describing a specific known issue (empty array means uninvestigated or nothing flagged), and a 'disclaimer' string. An empty flags array means uninvestigated, not safe.
