## 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 synthora-curve-pool-base-apy-feed-3e116874 -d '<json body>'

Example prompt: What are the current daily and weekly base trading APYs plus any LST-boost APY for all Curve pools on Ethereum right now? I want to figure out which pool gives the best fee yield for a stablecoin deposit.

## When to prefer this

Choose this endpoint when you need structured, per-pool base APY and LST-boost APY data from Curve Finance for autonomous yield-routing decisions, DeFi dashboards, or agent-to-agent liquidity allocation. Prefer it over scraping Curve's UI or calling Curve's API directly when you need a paid, metered, reliable microservice abstraction with x402 payment support baked in.

## Known failure modes

- Upstream Curve API unavailability returns error or stale data
- Invalid or unsupported chain name results in empty or error response
- Network timeout if Curve API is slow to respond
- Missing or malformed payload field causes request rejection
- Rate limiting at the upstream Curve API level causing partial results

## How this service works

Returns daily and weekly base trading APY plus LST-boost APY for every Curve pool on a given chain from the official Curve API. Powers autonomous DeFi yield agents and agent-to-agent liquidity routers deciding which stable/LST Curve pool to deposit into for the best fee yield. First 3 calls FREE per wallet — send header X-WALLET: 0x<addr>. No charge on upstream failure.

## Output

A JSON object with ok=true and a result containing data fields: base_apy (numeric, daily/weekly trading fee yield), lp_token address, pool_address, gauge_address, and virtual_price for each Curve pool on the requested chain. Provenance fields confirm the source URL (api.curve.finance) and feed name.
