## 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 barker-pool-detail-f31b21cf
```

Example prompt: Pull up the full pool dossier for pool ID 'aave-v3-usdc-eth' — I want to see all the APY components, TVL, reward breakdown, and whether it supports direct execution.

## When to prefer this

Use this endpoint after using barker_defi_vaults or barker_yield_advisor to get a shortlist of pools — this endpoint provides the deep-dive detail on a single specific pool. Prefer this over the list/advisory endpoints when you need granular APY component breakdown, execution capability confirmation, or full reward token details for a specific pool_uid.

## Known failure modes

- Invalid or unknown pool_uid returns an error or empty result
- Pool may have been delisted from Barker's index since it was retrieved
- Transient network or protocol errors may return 5xx responses
- APY data may be slightly stale if the pool hasn't been updated recently

## How this service works

Full single-pool dossier by pool_uid: all APY components (percent unit), TVL, terms, execution capability, reward breakdown. Use after barker_defi_vaults / barker_yield_advisor to inspect one pool.

## Output

A comprehensive pool dossier including all APY components expressed in percent units (base yield, reward tokens, etc.), current TVL, pool terms (lockup, minimum deposit, etc.), whether the pool supports direct on-chain execution via Barker, and a full reward token breakdown.
