## 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-price-oracle-2e6dac7b
```

Example prompt: I'm building an x402 API that checks wallet approval risk — it's a protection-tier tool. What should I charge for it? Give me a data-driven price recommendation and sensible range based on what live lanes are actually charging.

## When to prefer this

Use this endpoint when you need data-driven pricing guidance for an x402 API lane before launch or repricing. It is specifically tuned to the x402 micro-payment ecosystem with 100+ real lane samples, making it far more relevant than generic SaaS pricing tools for this niche. Prefer it when you want a category-specific recommended tier and range, not just a generic 'charge what the market bears' answer.

## Known failure modes

- Missing required 'description' query parameter returns an error — description is mandatory
- Category not recognized falls back to auto-detection from description keywords, which may misclassify edge cases
- Pricing data reflects a snapshot dataset (dated) and may not reflect very recent market shifts
- Service hosted on Render free tier may have cold-start latency or downtime impacting availability
- Description exceeding 2000 characters may be truncated or rejected

## How this service works

Proof of reliability: the public Lane Trust Index (https://mini-tollbooth.onrender.com/trust-index) scores all 101 lanes on uptime, latency, success rate and fail-closed rate. The insurance booth for AI agents, with Mini's Agent Supply Store on the side of the road. Seventy-one 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, and /trust 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 containing the lane name, dataset summary (100 live lanes), a recommended price tier in USD, a sensible price range (low/high), a category-level price distribution, a market positioning label (e.g. 'mid-market'), and a disclaimer that this is pricing intel rather than a guarantee. Helps API builders calibrate their x402 pricing against real market data.
