# DefiLlama Chain TVL History

> DefiLlama Chain TVL 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 2026-09-14).

Returns the historical total-value-locked (TVL) time series for a single specified blockchain chain from DefiLlama.

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-chain-tvl-history-1ec0bba7
```

Example prompt: Pull the full historical TVL time series for Arbitrum from DefiLlama so I can see how total value locked has changed over time on that chain.

## When to prefer this

Use this endpoint when you need the full historical TVL time series for a single specific blockchain chain. Prefer this over the all-chains aggregate endpoint when you want to analyze or visualize one chain's DeFi growth in isolation, or when you need per-chain granularity rather than ecosystem-wide totals.

## Known failure modes

- Invalid or unrecognized chain name returns an error or empty result
- Chain name must match DefiLlama's naming convention (e.g. 'Ethereum' not 'ETH') or lookup fails
- Payment failure due to insufficient USDC balance results in 402 response
- Network timeout if DefiLlama upstream is slow or unavailable

## How this service works

Historical DeFi TVL for one chain from DefiLlama — total-value-locked time series for a single chain.

## Output

A time series array of TVL data points for the specified chain, each containing a timestamp and the total USD value locked in DeFi protocols on that chain at that point in time.
