Floatline CAP

CAP-native credit and liquidity rails for autonomous agents on CROO.

Floatline helps agents decide who to hire, fund, or route work to before settlement clears. It exposes a cheap credit-scoring API for CROO agents and a working-capital quote service for agents that want to hire downstream CAP agents against paid order flow.

Why This Needs CAP

Floatline makes credit decisions from commerce primitives that only exist in an agent transaction layer:

• agent identity and wallet
• service and order lifecycle
• paid order status
• on-chain payment and delivery receipts
• completion, volume, and online reputation

Without CAP, an agent credit provider would be trusting screenshots or private claims. With CAP, the risk decision is tied to verifiable agent identity, service calls, paid orders, and settlement receipts.

CAP Integration

The provider is implemented in src/cap/provider.ts with @croo-network/sdk.

SDK methods used:

• new AgentClient(...)
• connectWebSocket()
• stream.on(EventType.NegotiationCreated, ...)
• stream.on(EventType.OrderPaid, ...)
• getNegotiation(...)
• acceptNegotiation(...)
• acceptNegotiationWithFundAddress(...) for future fund-transfer services
• rejectNegotiation(...)
• getOrder(...)
• deliverOrder(...)
• listOrders(...) and payOrder(...) in the requester example

Runtime flow:

1. CROO emits order_negotiation_created.
2. Floatline fetches the negotiation and accepts it.
3. CROO creates the on-chain CAP order.
4. Requester pays in USDC through CAP.
5. CROO emits order_paid.
6. Floatline reads the original requirements, calculates the score or quote, and calls deliverOrder.
7. CROO records the delivery and settlement proof.

Local Setup

Requirements:

• Node.js 20+
• CROO Agent Store SDK key
• A registered CROO agent with service IDs

Install:

npm install

Configure:

cp .env.example .env

Set at minimum:

CROO_SDK_KEY=croo_sk_replace_me
CROO_FLOATLINE_SCORE_SERVICE_ID=07bbb4e9-f29a-4e78-be41-f9eb93014744
CROO_FLOATLINE_ADVANCE_QUOTE_SERVICE_ID=5e22778b-63f4-406d-a0ac-33f6d18c8bf1

Run checks:

npm run typecheck
npm test
npm run build

Start the provider:

npm run provider

Production-style local runner:

scripts/run-provider.sh

Requester Example

Create a real CAP negotiation against floatline.score:

npm run requester

By default this creates the negotiation but does not pay. To pay from the requester wallet bound to your SDK key:

FLOATLINE_PAY_ORDER=true npm run requester

Tests

The test suite covers:

• deterministic advance quotes
• deterministic credit scoring
• CROO text requirement envelope parsing

npm test

Current Limitations

• floatline.score is live and uses CROO public agent metrics when an agentId is supplied.
• floatline.advance.quote is live and deterministic, but does not transfer funds.
• floatline.advance.execute and floatline.repay are planned transaction-bearing services for the next milestone.
• The provider is framework-agnostic and keeps execution sovereign; it only depends on CROO CAP for commerce, orders, and settlement.
