# PoolProof Known-Issues Research Lookup

> PoolProof Known-Issues Research Lookup is a paid API for AI agents from poolproof.ru, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-13).

Returns curated research flags on DeFi assets, protocols, chains, or roles covering dead redemption bridges, ticker collisions, ended points programmes, closed marketplaces, and capital gates that price feeds and TVL data won't surface

## 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-lookup-dab2e6f2 -d '<json body>'
```

Example prompt: Before I move funds into this protocol, check poolproof's known-issues database for 'USDR' — I want to know if there are any dead redemption bridges, ticker collisions, ended points programmes, or capital gates that the TVL numbers wouldn't tell me.

## When to prefer this

Choose this endpoint when you need qualitative, curated intelligence about a DeFi asset or protocol that quantitative feeds (price, TVL, volume) cannot provide — specifically for known structural risks like dead bridges, ticker ambiguity, closed programmes, or capital gates. Use it as a pre-flight check before entering or exiting a DeFi position, especially when on-chain data looks healthy but you suspect hidden risks. It complements TVL and yield-safety endpoints rather than replacing them.

## Known failure modes

- Asset or protocol not in database returns empty flags array — should not be interpreted as a clean bill of health
- Ambiguous identifiers (common ticker symbols) may return flags for the wrong project
- Database may not reflect very recent events if research notes haven't been updated
- Malformed input schema may cause a 400 error or unexpected response
- Rate limiting or payment failure on the x402 micropayment layer may block the call

## 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

A JSON object with a boolean 'ok' field, a 'verdict' string summarising the overall finding, an array of 'flags' each containing a 'code' and human-readable 'msg' describing a specific known issue (empty array means no recorded issues, not a safety guarantee), and a 'disclaimer' reminding users that absence of flags means uninvestigated rather than safe.
