# SYNTHORA Chain TVL

> SYNTHORA Chain TVL is a paid API for AI agents from chain-tvl.hergertsynthora.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-13).

Returns real-time total value locked (TVL) per blockchain with 24-hour change, sourced from DefiLlama, as a capital-flow signal for DeFi allocation decisions.

## Facts

- Endpoint: POST https://chain-tvl.hergertsynthora.com/service
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-13
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/synthora-chain-tvl-c741b0a0

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 synthora-chain-tvl-c741b0a0 -d '<json body>'
```

Example prompt: What's the current total value locked on each major blockchain, and which chains have seen the biggest TVL changes in the last 24 hours?

## When to prefer this

Choose this endpoint when you need real-time, per-chain TVL data with 24h delta signals for automated DeFi capital allocation, chain comparison, or trend monitoring. It is backed by DefiLlama, the canonical DeFi TVL aggregator, and is cost-effective at $0.001 per call via x402, making it ideal for high-frequency agent polling or decision loops.

## Known failure modes

- DefiLlama upstream unavailability returns degraded or empty result set
- Malformed POST body may return a 400 or failed ok status
- Transient network errors may delay real-time data freshness
- Payment failure via x402 on Base returns 402 before data is served

## How this service works

Real-time total value locked per blockchain via DefiLlama, with 24h change. Capital-flow signal for allocation agents. Free source. $0.01 USDC via x402 on Base. SYNTHORA. First 3 calls FREE per wallet — send header X-WALLET: 0x<addr>. No charge on upstream failure.

## Output

A JSON object containing chain-level TVL data sourced from DefiLlama, including total value locked per blockchain and the 24-hour change in TVL, usable as a capital-flow signal for automated allocation decisions.
