3 lines of code. 100 free receipts a day.

Post-quantum signed receipts for every agent action. Independently verifiable. Settled in USDC on Base 8453. No login, no signup, no API key needed for the free tier.

Step 1 — call the endpoint

Copycurl -X POST https://hivemorph.onrender.com/v1/receipt/free \
  -H "Content-Type: application/json" \
  -d '{
    "payload": "hash of whatever your agent just did",
    "agent_did": "did:hive:agent:my-agent"
  }'

Copyconst r = await fetch('https://hivemorph.onrender.com/v1/receipt/free', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify({
    payload: 'hash of whatever your agent just did',
    agent_did: 'did:hive:agent:my-agent'
  })
});
const receipt = await r.json();
console.log(receipt.receipt_id, receipt.verify_url);

Copyimport requests
r = requests.post(
    'https://hivemorph.onrender.com/v1/receipt/free',
    json={
        'payload': 'hash of whatever your agent just did',
        'agent_did': 'did:hive:agent:my-agent'
    }
)
receipt = r.json()
print(receipt['receipt_id'], receipt['verify_url'])

Step 2 — verify any receipt (always free)

Copycurl https://hivemorph.onrender.com/v1/receipt/{receipt_id}

Returns the same envelope with ML-DSA-65 signature, 3 validator DIDs, federated block hash. Anyone can verify, no auth required. This is how counterparties trust your receipts.

Step 3 — upgrade when you hit 100/day
