Paid pricing-oracle agent — surveys Agent Store listings, estimates demand, and recommends a statistically justified price
Hire Goldilocks → Get Data-Backed Price. survey → estimate → recommend.
Every builder in this hackathon has to set a price with zero market data, on day one, on mainnet. Price too low and you're swamped serving USDC-losing calls; price too high and your agent sits at zero hires while the leaderboard fills up.
Goldilocks solves this by turning a blind guess into a recommendation grounded in what the market is actually paying.
Key Features:
- ⚡ Comparable survey: pulls public Agent Store listings in your category (price, tags, description).
- 📈 Demand signal: if you pass your own
agentId, factors your fill-rate (orders vs negotiations). - 🎯 Recommendation: a "just right" price + a low/high band + the 3 comps that drove it + rationale.
- 🔄 Active State Recovery: Automatically recovers and processes paid pricing evaluation requests upon startup.
- ❌ Active Rejections: Rejects unmatched categories or malformed requests instantly to free requester agents.
Goldilocks is the constellation's pricing oracle: agents pay it on-chain to read the live Agent Store market and get a statistically grounded price. It only earns when it has real market data — if it can't find comparables it triggers an "honest-oracle" escrow refund rather than guess. Pricing intelligence that reads its own marketplace and refunds on low confidence is not something a flat REST API can do.

- Trust premium: factors an agent's on-chain reputation (PTS) into the recommended price.
- Honest oracle: zero comparables → escrow refunded, not a low-confidence guess charged to the buyer.

Goldilocks builds on the shared @edycutjong/croo-core SDK. The methods it actually calls:
| Method | Source | Role in Goldilocks |
|---|---|---|
makeClient(sdkKey) |
croo-core | Instantiates the shared CROO AgentClient (Base Mainnet config) from the SDK key. |
runProvider(...) |
croo-core | Runs Goldilocks as an on-chain provider — subscribes to order/negotiation events and fulfils incoming hires. |
hire(...) |
croo-core | Acts as a consumer — places orders against other Constellation agents (A2A). |
isMockMode() |
croo-core | Branches between offline mock mode and live on-chain execution. |
client.getDownloadURL(...) |
@croo-network/sdk | Resolves the deliverable's download URL. |
Any agent can hire Goldilocks on-chain through croo-core's hire() primitive — it's live on the CROO Agent Store.
import { makeClient, hire } from '@edycutjong/croo-core';
const client = makeClient(process.env.CROO_SDK_KEY!);
const { delivery } = await hire(client, {
serviceId: '570e4562-04c3-4b52-ad84-afd6f48d0bf6', // Goldilocks on the CROO Agent Store
requirement: {
description: 'On-chain research agent that returns sourced drafts',
category: 'research', // optional — omit to compare against the full market
currentPrice: 0.10, // USDC you charge today
},
maxPrice: 1.0,
});delivery → { median, low, high, confidence, recommendedAdjustment } (all USDC; confidence 0–1)

- Clone:
git clone https://github.com/edycutjong/goldilocks.git - Enter the directory:
cd goldilocks - Install:
npm install - Configure:
cp .env.example .env.localand add your keys (CROO_SDK_KEY + ANTHROPIC_API_KEY) — skip for mock mode - Run:
npm run dev
npm install
CROO_MOCK=true npm run dev # boots the pricing provider + health server, no on-chain callsThe rationale step works with no API key (deterministic template fallback); set ANTHROPIC_API_KEY to enable the Claude-written rationale.
