## 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 agentdiet-pendle-pt-yields-lookup-d179e33d
```

Example prompt: What are the current Pendle PT yields right now — can you pull the latest fixed yield rates, and filter by USDC if possible?

## When to prefer this

Choose this endpoint when you need current Pendle Finance Principal Token yield data in a pay-per-call, agent-native (x402/L402) context — especially when operating within an A2A or MCP pipeline that handles micropayments in USDC on Base. Prefer this over scraping Pendle's UI or using heavier RPC calls when you only need summarized yield rates.

## Known failure modes

- Payment not settled — 402 response if USDC payment on Base is not provided or fails
- Invalid asset query parameter returns empty or error data
- Upstream Pendle Finance data unavailable causes degraded or stale response
- Malformed request method (non-GET) returns schema validation error
- Rate limiting or node unavailability returns a non-200 status

## How this service works

Deterministic B2A/A2A/MCP/x402/MPP/L402 execution and intelligence node at https://status.agentdiet.dev settling in USDC on Base.

## Output

Returns a JSON object with a 'data' field containing Pendle PT yield information, a 'status' field indicating success, and an 'roi_proof' object with a compression_ratio_pct value (e.g. 91.4%) reflecting AgentDiet's context compression metrics.
