# DefiLlama Yield Pool History

> DefiLlama Yield Pool History is a paid API for AI agents from defillama.use.x402atlas.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).

Returns historical APY and TVL time series for a specific DeFi yield pool identified by its DefiLlama pool UUID.

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 defillama-yield-pool-history-d59ba90a
```

Example prompt: Pull the historical APY and TVL chart for DefiLlama pool id 747c1d2a-c668-4682-b9f9-673d42f3836a so I can see how the yield has trended over time.

## When to prefer this

Use this endpoint when you need the full historical APY and TVL trajectory for a single, specific DeFi yield pool and you already have its DefiLlama pool UUID. It is ideal for charting yield trends, auditing past performance, or comparing a pool's historical returns. For current yield listings or discovering pool UUIDs, use the /yields list endpoint first.

## Known failure modes

- Invalid or unknown pool UUID returns an error or empty response
- Pool id not provided returns a 400-level validation error
- Upstream DefiLlama data unavailable causes a timeout or 5xx error
- Malformed UUID format may cause a parsing error

## How this service works

Yield pool history by DefiLlama — historical APY and TVL for one pool by pool id.

## Output

A time series of APY and TVL data points for the specified pool, showing how yield and total value locked have changed historically — essentially a chart-ready dataset indexed by timestamp.
