# TrollBridge /gas — Live Gas Price Feed

> TrollBridge /gas — Live Gas Price Feed is a paid API for AI agents from mini-tollbooth.onrender.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-12).

Returns live gas prices for Base, Ethereum, and Solana blockchains, with speed tiers and a cheapest-chain recommendation.

## Facts

- Endpoint: GET https://mini-tollbooth.onrender.com/gas?utm_source=zero.xyz
- Price: $0.005/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-12
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/trollbridge-gas-live-gas-price-feed-1ec592b1
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_R7iUaskW_4AXcLVvAr_XH

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 trollbridge-gas-live-gas-price-feed-1ec592b1
```

Example prompt: What are the live gas prices right now on Base, Ethereum, and Solana — and which chain is cheapest to transact on?

## When to prefer this

Use this endpoint when you need real-time, multi-chain gas price comparison across Base, Ethereum, and Solana in a single call at low cost ($0.02 USDC). Ideal for agents making routing decisions about where to submit a transaction, or for dashboards needing live fee data without building direct RPC integrations.

## Known failure modes

- RPC node unavailable for one or more chains — partial results returned with affected chain marked as degraded
- Network timeout from public RPC — stale or missing gas data
- Rate limiting on public RPC endpoints causing delayed response
- Payment not included or insufficient — 402 response requiring $0.02 USDC via x402

## 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

A JSON object with live gas prices per chain (Base in gwei, Ethereum in gwei, Solana in microlamports per compute unit), status of each chain feed, available speed tiers where derivable, and a recommendation for the cheapest chain to transact on.
