# TrollBridge Chain TVL Leaderboard

> TrollBridge Chain TVL Leaderboard is a paid API for AI agents from mini-tollbooth.onrender.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-11).

Returns ranked DeFi total value locked (TVL) data for all 468 tracked blockchain networks, or TVL details for a single specified chain, sourced from DeFiLlama.

## 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 trollbridge-chain-tvl-leaderboard-bb22fcb3
```

Example prompt: What's Ethereum's current DeFi TVL, its rank among all chains, and its share of the total tracked TVL — pull it from DeFiLlama via TrollBridge?

## When to prefer this

Choose this endpoint when you need fast, ranked TVL data across all major blockchains or want to look up a specific chain's DeFi TVL, rank, and share of total value locked. It aggregates DeFiLlama data into a single cheap ($0.02) call, making it ideal for market intelligence dashboards, chain comparison workflows, or DeFi research agents that need ecosystem-level TVL context without building a DeFiLlama integration from scratch.

## Known failure modes

- Invalid or misspelled chain name returns no single-chain result
- DeFiLlama upstream outage may cause stale or missing data
- Payment of $0.02 USDC not provided results in 402 Payment Required response
- Querying a chain not tracked by DeFiLlama returns null or empty result

## How this service works

The insurance booth for AI agents, with Mini's Agent Supply Store on the side of the road. One hundred checkpoints: pre-transaction safety lanes (honeypot, approval-risk, rug-score, receipt-check, tx-dryrun, permit-scan, airdrop-verdict, deployer-history, wallet-watch, secret-scan at $0.02 USDC per call; the protection tier — /contract-check, /approval-screen, /tx-plain-english, /honeypot-check, /tx-simulate, /redteam, /skill-scan, /verdict, /egress-audit, /tool-gate, /airlock, /repo-scan, /prove, /task-scope — at $0.10; the one-call /shield don't-get-rugged screen at $0.25; the full /preflight bundle at $0.05), bounty intel (bounties, fresh, verdicts, deadlines, sweepstakes, opportunities) at $0.02 USDC per call, trader intel (/prices and /quant at $0.02; /enrich and /token-check at $0.05; /contract-check and /honeypot-check at $0.10; /sec-facts at $0.05), market intel (/markets and /search at $0.05; /grants at $0.02), DeFi intel (/yields and /new-pairs at $0.05; /gas and /defi at $0.02), AI intel (/models at $0.02), agent-ops intel (/prompt-cost, /model-picks, /rpc-speed, /terms-tldr, /scrape, /gigs, /retry-verify, /idempotency, /verify-independent at $0.02; /site-watch, /wallet-check, /code-run, /regulatory-pack, /sage, /cron-watch, /caveat-check, /tripwire, /escrow, /trust, /bridge-fees, /dao-votes, /dev-activity, /dex-arb, /dydx-perps, /funding-rates, /gas-predict, /hack-tracker, /long-short-ratio, /lp-yields, /mev-scan, /open-interest, /perp-basis, /polymarket-odds, /rwa-watch, /sentiment, /stablecoin-flows, /tokenomics, /top-movers, /whale-watch, and /yield-stable at $0.05; /approval-screen, /tx-plain-english, /tx-simulate, and /task-scope at $0.10; /scam-scan deep scan at $5.00 or 30-day subscription at $30.00), supply store (/road-pack combo meal at $0.05; curated datasets, the /audit-prep pre-audit review, and the /prove-state symbolic-execution run at $1.00; the /audit AI-agent audit at $25.00). Every lane answers before money moves — heuristic verdicts, not audits. Don't get rugged.

## Output

Returns a JSON object with the chain name, TVL in USD, rank, share of total TVL as a percentage, gas token, chain ID, gecko ID, total TVL across all 468 tracked chains, and chains tracked count. In list mode, returns the top 25 chains by TVL. Includes a note that TVL is self-reported via DeFiLlama adapters and represents a leaderboard snapshot, not an audit.
