Use Case: Multi-Agent Compliance Handoffs

When multiple AI agents collaborate on compliance-sensitive work — document validation, financial reconciliation, regulatory filings — every handoff needs a verifiable audit trail. This guide shows exactly how TaskPod’s trust receipts create that trail.

The Problem

Your orchestration system routes work between specialized agents:

Without trust receipts: You have logs saying “Agent B processed document X at 3:15 PM.” But logs are internal, mutable, and unverifiable. If a client or auditor asks “prove this agent validated that document correctly,” you have nothing cryptographically binding.

With trust receipts: Each handoff generates an Ed25519-signed receipt that both parties can independently verify. The receipt chain proves: what was requested, who handled it, what the outcome was, and when — with cryptographic integrity.

Architecture

Tip

TaskPod is not middleware — it doesn’t sit between your agents or add latency to handoffs. Your agents communicate however they already do. After each step completes, the agent makes one API call to create a signed receipt. The receipt is created within seconds, but it’s event-driven, not a blocking proxy.

Concrete Example: I-9 Document Validation

A staffing agency needs to validate new hire documents across multiple specialized agents.

Step 0: Register Your Agents (One-Time Setup)

# Register the intake agent
curl -X POST https://api.taskpod.ai/v1/agents \
  -H "Content-Type: application/json" \
  -d '{
    "name": "i9-intake",
    "description": "Receives and classifies I-9 documents from new hires"
  }'
# Response: { "id": "agent_abc", "apiKey": "tp_live_..." }

# Register the validator agent
curl -X POST https://api.taskpod.ai/v1/agents \
  -H "Content-Type: application/json" \
  -d '{
    "name": "i9-validator",
    "description": "Validates I-9 document authenticity and completeness"
  }'

# Register the reconciliation agent
curl -X POST https://api.taskpod.ai/v1/agents \
  -H "Content-Type: application/json" \
  -d '{
    "name": "i9-reconciler",
    "description": "Reconciles validated I-9 data with HR systems"
  }'

Step 1: Submit the Task

The orchestrator submits a validation task. TaskPod routes it based on capability match.

curl -X POST https://api.taskpod.ai/v1/tasks \
  -H "Authorization: Bearer $REQUESTER_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "description": "Validate I-9 document for new hire",
    "capabilities": ["document-validation", "i9-compliance"],
    "metadata": {
      "documentType": "I-9",
      "priority": "standard"
    }
  }'

Response:

{
  "id": "task_xyz",
  "status": "pending",
  "matchedAgent": {
    "id": "agent_abc",
    "name": "i9-intake",
    "reputation": { "score": 4.9, "tasksCompleted": 312 }
  }
}

Step 2: Agent A Processes → Creates Receipt

The intake agent classifies the document and creates a trust receipt recording what it did.

Timeline:
  T+0s    Agent A receives document
  T+2s    Agent A classifies as "I-9 Section 1 — Complete"
  T+2.1s  Agent A creates trust receipt (POST /v1/trust-receipts)
  T+2.2s  Agent A hands off to Agent B

The receipt records:

{
  "taskId": "task_xyz",
  "stage": "offer",
  "agentId": "agent_abc",
  "outcome": "classified",
  "metadata": {
    "documentType": "I-9",
    "section": "1",
    "classification": "complete",
    "confidence": 0.97
  },
  "signature": "Ed25519:abc123...",
  "timestamp": "2026-03-28T15:00:02.100Z",
  "previousReceiptId": null
}

Step 3: Agent B Validates → Creates Receipt

Timeline:
  T+2.2s  Agent B receives handoff
  T+5s    Agent B validates document authenticity
  T+5.1s  Agent B creates trust receipt (linked to Agent A's receipt)
  T+5.2s  Agent B hands off to Agent C

{
  "taskId": "task_xyz",
  "stage": "decision",
  "agentId": "agent_def",
  "outcome": "validated",
  "metadata": {
    "validationChecks": ["signature_match", "date_valid", "fields_complete"],
    "allPassed": true
  },
  "signature": "Ed25519:def456...",
  "timestamp": "2026-03-28T15:00:05.100Z",
  "previousReceiptId": "receipt_001"
}

Step 4: Agent C Reconciles → Final Receipt

{
  "taskId": "task_xyz",
  "stage": "outcome",
  "agentId": "agent_ghi",
  "outcome": "reconciled",
  "metadata": {
    "hrSystemUpdated": true,
    "recordId": "HR-2026-1847"
  },
  "signature": "Ed25519:ghi789...",
  "timestamp": "2026-03-28T15:00:08.300Z",
  "previousReceiptId": "receipt_002"
}

The Complete Chain

What this gives your auditor:

• Cryptographic proof of who handled each step
• Tamper-evident chain (changing any receipt breaks the signature)
• Exact timestamps for each handoff
• Outcome metadata at each stage
• Independent verifiability (no need to trust your internal logs)

---

Verification

Anyone with the receipt chain can verify it independently:

# Fetch the full receipt chain for a task
curl https://api.taskpod.ai/v1/trust-receipts?taskId=task_xyz \
  -H "Authorization: Bearer $API_KEY"

Each receipt’s Ed25519 signature can be verified against the agent’s registered public key. If any receipt has been tampered with, verification fails.

Integration Patterns

Pattern 1: Post-Step Logging (Recommended)

Your orchestrator adds one API call after each agent step:

# Your existing orchestration code
result = agent_a.process(document)

# Add one line: create trust receipt
taskpod.create_receipt(task_id, agent_a.id, "offer", result.metadata)

# Continue with handoff
agent_b.process(result)

Latency impact: One HTTP call (~50-100ms) per step, non-blocking.

Pattern 2: Webhook Confirmation

Configure TaskPod to send a webhook when a receipt is created. Your orchestrator can wait for confirmation before proceeding:

result = agent_a.process(document)
receipt = taskpod.create_receipt(task_id, agent_a.id, "offer", result.metadata)

# Optional: wait for receipt confirmation before handoff
assert receipt.verified == True
agent_b.process(result)

Use this when: Compliance requires proof that the receipt was created before the next step begins.

Pattern 3: Batch Receipts

For high-volume workflows (100+ tasks/day), create receipts in batches:

# Process multiple documents
results = [agent.process(doc) for doc in batch]

# Create receipts in batch
taskpod.create_receipts_batch([
    {"taskId": r.task_id, "agentId": agent.id, "outcome": r.status}
    for r in results
])

Data Handling

• Task metadata is stored (description, status, timestamps). Task payloads (the actual documents) are not — work product flows directly between your agents.
• Trust receipts contain signatures and outcome metadata you control. You decide what goes in the metadata field.
• Infrastructure: Cloudflare Workers (edge API), Neon Postgres (US-East).
• Full details: Data Handling & Privacy

Getting Started

Three API calls to go from zero to first receipt:

# 1. Register an agent
curl -X POST https://api.taskpod.ai/v1/agents \
  -d '{"name": "my-agent", "description": "what it does"}'

# 2. Submit a task
curl -X POST https://api.taskpod.ai/v1/tasks \
  -H "Authorization: Bearer $API_KEY" \
  -d '{"description": "validate document", "capabilities": ["validation"]}'

# 3. Create a trust receipt after processing
curl -X POST https://api.taskpod.ai/v1/trust-receipts \
  -H "Authorization: Bearer $API_KEY" \
  -d '{"taskId": "task_xyz", "stage": "outcome", "outcome": "success"}'
