Receipts

Every completed tool execution generates a receipt — your proof of work and payment.

​
What’s in a Receipt?

Getting Receipts

​
In Tool Response

Every tool call includes receipt metadata: 
{
  "result": {
    "content": "...",
    "_meta": {
      "receipt_id": "rcpt_abc123",
      "debited_usdc_microusd": 85000
    }
  }
}

​
Query Receipt

Retrieve full receipt details: 
curl -X POST https://agent.asgcompute.com/mcp \
  -H "Content-Type: application/json" \
  -d '{
    "jsonrpc": "2.0",
    "id": 1,
    "method": "tools/call",
    "params": {
      "name": "billing_get_receipt",
      "arguments": {
        "receipt_id": "rcpt_abc123"
      }
    }
  }'

​
Receipt Retention

Receipts are stored for 30 days. Export receipts for accounting purposes before expiration.

​
Verify a Receipt

Every receipt is independently verifiable — both through the ASG API and directly on the Solana blockchain.

​
Step 1: Look Up the Receipt

Use the billing_get_receipt tool to retrieve full receipt details by ID: 
curl -X POST https://agent.asgcompute.com/mcp \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -d '{
    "jsonrpc": "2.0",
    "id": 1,
    "method": "tools/call",
    "params": {
      "name": "billing_get_receipt",
      "arguments": {
        "receipt_id": "rcpt_2026020812345"
      }
    }
  }'
Response: 
{
  "result": {
    "content": [
      {
        "type": "text",
        "text": "{\"receipt_id\":\"rcpt_2026020812345\",\"tool\":\"inference_chat\",\"quoted_usdc_microusd\":2400,\"debited_usdc_microusd\":2400,\"tx_signature\":\"5UxK...7nPq\",\"created_at\":\"2026-02-08T12:00:00Z\"}"
      }
    ]
  }
}

​
Step 2: Verify On-Chain

Every receipt includes a tx_signature field — the Solana transaction signature. Use it to verify the payment on-chain: Solana Explorer URL format: 
https://explorer.solana.com/tx/<TX_SIGNATURE>
For example, if tx_signature is 5UxK...7nPq: 
https://explorer.solana.com/tx/5UxK...7nPq
Bookmark the Solana Explorer link for quick access: explorer.solana.com

​
Step 3: Cross-Reference

Verify that the on-chain transaction matches your receipt:
Receipt FieldOn-Chain Check
debited_usdc_microusdAmount transferred matches
tx_signatureTransaction exists and is finalized
created_atTimestamp aligns with block time
All Solana transactions are on mainnet. Ensure you’re viewing the mainnet explorer, not devnet.

​
Programmatic Verification

For automated verification, you can query the Solana RPC directly: 
curl -X POST https://api.mainnet-beta.solana.com \
  -H "Content-Type: application/json" \
  -d '{
    "jsonrpc": "2.0",
    "id": 1,
    "method": "getTransaction",
    "params": [
      "YOUR_TX_SIGNATURE",
      { "encoding": "json", "maxSupportedTransactionVersion": 0 }
    ]
  }'
This returns the full transaction details including sender, recipient, amount, and confirmation status.
