crewai-a2a-settlement

Bridge CrewAI multi-agent orchestration with the A2A Settlement Exchange — enabling AI agents to automatically pay each other in tokens for completed tasks using escrow-based settlement.

How It Works

When one agent (e.g., an orchestrator) assigns a task to another (e.g., a scraper), tokens are held in escrow, then released on success or refunded on failure — all transparently wrapped around CrewAI's existing task execution flow.

Orchestrator ──► Escrow (lock tokens) ──► Worker executes task
                                              │
                                    ┌─────────┴─────────┐
                                 Success              Failure
                                    │                    │
                              Release funds        Cancel / refund
                              to Worker            to Orchestrator

Installation

pip install crewai-a2a-settlement

With CrewAI integration (for SettledAgent, SettledTask, SettledCrew — coming in v0.2):

pip install "crewai-a2a-settlement[crewai]"

Quick Start

from crewai_a2a_settlement import A2AConfig, A2ASettlementClient

# 1. Configure (reads A2ASE_API_KEY from env by default)
config = A2AConfig(api_key="your-sandbox-key")

# 2. Initialize the client
client = A2ASettlementClient.initialize(config)

# 3. Register agents
payer = client.register_agent("Orchestrator", ["orchestrate"])
payee = client.register_agent("Scraper", ["web_scraping"])

# 4. Escrow → execute → release/cancel
receipt = client.escrow(
    payer_address=payer,
    payee_address=payee,
    amount=5.0,
    task_id="scrape-task-001",
    description="Scrape product data from example.com",
)

# On success:
result = client.release(receipt.escrow_id)
print(f"Released! tx_hash={result.tx_hash}")

# Or on failure (cancel = refund):
# result = client.cancel(receipt.escrow_id, reason="Scraper timed out")

# 5. Session summary
summary = client.get_session_receipts()
print(summary)

Configuration

| Env Variable | Default | Description | |---|---|---| | A2ASE_API_KEY | (required) | API key from sandbox.a2a-settlement.org | | A2ASE_EXCHANGE_URL | https://sandbox.a2a-settlement.org | Exchange base URL (no /v1) | | A2ASE_NETWORK | sandbox | sandbox, devnet, or mainnet | | A2ASE_TIMEOUT | 30 | HTTP timeout in seconds | | A2ASE_AUTO_REGISTER | true | Auto-register agents at crew kickoff |

Or pass values directly:

config = A2AConfig(
    api_key="sk-...",
    exchange_url="https://sandbox.a2a-settlement.org",
    network="sandbox",
    timeout_seconds=30,
)

Development

git clone https://github.com/a2a-settlement/crewai-a2a-settlement.git
cd crewai-a2a-settlement
pip install -e ".[dev]"
pytest

Test Coverage

The v0.1.0 test suite covers 64 tests across:

Singleton client lifecycle
Agent registration (success, auth failure, retries)
Escrow creation (success, insufficient balance, idempotency, retries)
Release and cancel (success, not-found, already-settled, retries)
Full lifecycle scenarios (register → escrow → release/cancel)
Session summary aggregation
Balance and history queries
HTTP error code mapping to typed exceptions
Retry logic with exponential backoff
Context manager support
Configuration validation

Roadmap

| Version | Scope | |---|---| | v0.1.0 | SDK client layer — A2ASettlementClient, config, models, typed errors, retry logic, session summary | | v0.2.0 | CrewAI integration — SettledAgent, SettledTask, SettledCrew, EscrowStatus enum, context manager escrow, sandbox utilities, thread safety, agent directory | | v0.3.0 | PyPI publish, CI/CD, ecosystem templates (LangGraph, AutoGen) |

Note: client.cancel() refunds escrowed funds (same as refund_escrow in other integrations).
