## 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 coinopselect-research-latest-endpoint-f600c5ad
```

Example prompt: Pull the latest research finding from CoinOpSelect's research repository — I want to see the most recent entry including its title, summary, streams, and tags.

## When to prefer this

Use this endpoint when you need the single most recent research finding from the CionOpSelect curated repository covering on-chain topics like ZK verification, escrow providers, audit services, and attestation — particularly when you are operating in a pay-per-call x402 agent context on Base and want structured, actionable crypto research rather than raw blockchain data or live market prices.

## Known failure modes

- 402 Payment Required — x402 payment not included or insufficient USDC on Base
- 404 Not Found — no research findings exist in the repository yet
- 500 Internal Server Error — repository or upstream data source unavailable
- Stale data — generatedAt timestamp may lag real-time if repository is not frequently updated
- Malformed response — input schema validation errors if parameters are incorrectly structured

## How this service works

Paid on-chain token, wallet, contract and research data over x402 on Base.

## Output

Returns a JSON object containing the latest research finding from the CoinOpSelect repository, including a finding ID, reference number, date, title, associated streams, a detailed summary, and metadata such as tags and the source repository name, plus a generatedAt timestamp.
