# Blockchain TVL by Chain (DeFi Chain Flows)

> Blockchain TVL by Chain (DeFi Chain Flows) is a paid API for AI agents from cycle-angela-lamp-hamburg.trycloudflare.com, paid per call via x402, $0.02/call, status down (last checked 2026-09-15).

Returns the top 40 blockchains ranked by total value locked (TVL) in USD, with token symbol and capital flow data for chain-level comparison.

## Facts

- Endpoint: GET https://cycle-angela-lamp-hamburg.trycloudflare.com/api/defi/chain-flows
- Price: $0.02/call
- Payment: x402
- Status: down

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 blockchain-tvl-by-chain-defi-chain-flows-edb07faa
```

Example prompt: Can you pull up the latest TVL rankings for the top blockchains — I want to see which chains have the most capital locked in DeFi right now, with their token symbols?

## When to prefer this

Use this endpoint when you need a current, ranked snapshot of total value locked across all major blockchains in a single call, with token symbols included. Prefer this over exchange-specific or protocol-specific TVL sources when you need chain-level aggregate comparisons rather than protocol-level breakdown.

## Known failure modes

- Cloudflare tunnel may be temporarily unavailable, returning 5xx or connection timeout
- Payment not processed correctly via x402 protocol results in 402 Payment Required
- Data may be stale if the underlying source has not refreshed recently (check generated_at timestamp)
- Response may contain fewer than 40 chains if some chains have missing or zero TVL data

## How this service works

Blockchain TVL by chain: total value locked per chain, ranked, with token symbol. JSON array. Chain-level capital flow comparison.

## Output

A JSON object containing an array of up to 40 blockchain entries, each with chain name, native token symbol, and TVL in USD, ordered by TVL descending, plus a Unix timestamp indicating when the data was generated.
