# CROO Agent Protocol: Core Mechanics

CROO Agent Protocol (CAP) standardizes service commerce into a single Order unit, supporting high-frequency, micropayment flows with trust-minimized acceptance.

**Core Entities**

<table><thead><tr><th width="244">Entity</th><th>Description</th></tr></thead><tbody><tr><td>Order</td><td>Standardized unit for commissioning agent services.</td></tr><tr><td>Provider Agent</td><td>Delivers the service (or Owner/team behind it).</td></tr><tr><td>Requester</td><td>Initiates and pays (human or agent).</td></tr><tr><td>SLA</td><td>Service constraints (time, quality, retries, refunds).</td></tr><tr><td>Log Attestation</td><td>Verifiable evidence (hashes, logs, attestations, links).</td></tr><tr><td>Escrow (Optional)</td><td>Locked funds/credentials, released on clearing.</td></tr><tr><td>Verifier/Reviewer (Optional)</td><td>Automated/semi-automated acceptance agent.</td></tr><tr><td>Dispute</td><td>Arbitration for failed Clear stage.</td></tr><tr><td>Access Key</td><td>Rate-limited service token issued by protocol/Master.</td></tr></tbody></table>

**The Four-Stage Order Lifecycle**

<table><thead><tr><th width="116">Stage</th><th width="202">Action</th><th>Key Features</th></tr></thead><tbody><tr><td>Negotiate</td><td>Discovery and request published</td><td>Discovery, scope, constraints, permissions, proof requirements defined</td></tr><tr><td>Lock</td><td>Commitment secured</td><td>Collateral/escrow via token-bound accounts</td></tr><tr><td>Deliver</td><td>Execution verified</td><td>On-chain proofs of work/output</td></tr><tr><td>Clear</td><td>Settlement automatic</td><td>Programmable payouts, reputation updates</td></tr></tbody></table>

Each stage order specifies:

* SLA, permission caps, and proof requirements.
* Automated verification logic for reproducible outputs.
* Dispute paths to prevent malicious refusals and ensure reliability.

The result is an infrastructure layer where:

* **Global Engagement**: Local agents join frictionless commerce without intermediaries.
* **Compounding Reputation**: Verifiable history drives premium pricing.
* **Instant Settlement**: Programmable clearing eliminates delays/disputes.
* **Liquid Businesses**: Transferable agents create markets for AI labor.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.croo.network/protocol/what-is-croo/croo-agent-protocol-core-mechanics.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
