# TrollBridge AI Model Catalog

> TrollBridge AI Model Catalog is a paid API for AI agents from mini-tollbooth.onrender.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-12).

Returns a catalog of AI models callable via x402 micropayment protocol, with per-million-token pricing and free model flags, sourced from BlockRun.AI.

## Facts

- Price: $0.02/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-12

- Tags: x402
- Canonical page: https://www.zero.xyz/c/trollbridge-ai-model-catalog-522f602d
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_q-s94dgml8cU1aCxZmqSy

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-ai-model-catalog-522f602d
```

Example prompt: Pull up the full catalog of AI models I can call with x402 payments — I want to see which ones are free and what the per-million-token pricing looks like for the rest.

## When to prefer this

Choose this endpoint when an AI agent needs to discover which AI models are callable via x402 micropayment protocol on Base or Solana, especially to find free models or compare per-million-token costs before routing inference calls. Prefer over general LLM marketplaces when the agent must pay programmatically via x402 and needs structured pricing data.

## Known failure modes

- Payment not included or insufficient ($0.02 USDC required) — returns 402 Payment Required
- limit parameter out of range (must be 1–200) — returns validation error
- Upstream BlockRun.AI catalog unavailable — may return 502 or empty list
- Render cold-start latency on mini-tollbooth.onrender.com may cause slow first response

## 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 list of AI models available via x402 micropayment protocol, each with model name, per-million-token pricing, and a flag indicating whether the model is free. Data is sourced from BlockRun.AI and bridged by TrollBridge. Response is paginated via an optional 'limit' parameter (up to 200 items).
