# AcePilot — Aero Pool Universe Facts

> AcePilot — Aero Pool Universe Facts is a paid API for AI agents from aeroacepilot.xyz, paid per call via x402, $0.05/call, status unknown (last checked 2026-11-01).

Returns historical on-chain evidence and metadata for all Aerodrome liquidity pools on Base, including query pricing and availability information.

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 acepilot-aero-pool-universe-facts-fbbda03a
```

Example prompt: What Aerodrome pool facts are available across the whole universe of Base pools — show me what data grains exist, what each query costs, and whether they're currently answerable before I commit any USDC.

## When to prefer this

Choose this endpoint when you need a broad, universe-level view of all available Aerodrome pool data grains on Base — particularly when you want to compare query types, check availability, and understand pricing before committing USDC. Prefer it over pool-specific endpoints (e.g. Slipstream range evidence) when you don't yet know which pool or metric you need, or when building a discovery/routing layer for Aero data queries.

## Known failure modes

- Payment not provided or insufficient USDC via x402 — returns 402 Payment Required
- Invalid or malformed query parameters — returns 400 Bad Request
- Pool universe data temporarily unavailable — grain may return non-ANSWERED state
- Rate limiting or quota exceeded — returns 429
- Answer integrity mismatch — SHA-256 hash does not match recomputed hash on client side

## How this service works

Historical on-chain evidence for Aero pools on Base. Compare query purposes, prices and availability before paying with x402 USDC.

## Output

Returns a JSON payload containing a grain answer with state (e.g. ANSWERED), a metrics object with pool-level facts, a grain_id (grain_universe_facts), schema version, delivery product info, and an integrity block including a SHA-256 hash of the answer canonicalized via JCS RFC 8785 v2 for verification.
