Sample of a real delivery: the buyer overpaid 0.5 KITE for a 0.01 brief. The slip labels the generation path as a direct fallback run.

Settled on Kite testnet, verified against KiteScan, sold by the hiremind-seller agent on the OpenServ network.

Topic in, brief out, receipt to prove it.

First, you ask for a price.

POST /api/brief
{ "topic": "x402 pay-per-call for AI agents" }

402 Payment Required
{ "price": "0.01", "currency": "KITE",
  "chainId": 2368, "address": "0x226c…" }
The API answers 402 with the fixed price and the seller address. No account, no key, just a number and a destination.

Then, you pay on Kite testnet.

send 0.01 KITE to 0x226c…59282
wait one confirmation
paste the transaction hash
The app reads the chain: right recipient, amount at least the price, confirmed transaction. Anything else is refused with a reason, never lost. Overpay and the receipt records what you actually paid.

Finally, the brief arrives with its receipt.

Summary

Agent reputation and trust scores are computational mechanisms that enable autonomous software agents to evaluate counterparty reliability in multi-agent systems and decentralized marketplaces.

Key findings

  • Composite trust scores blend on-chain history with off-chain attestations to resist Sybil attacks.
  • Portable reputation schemas use verifiable credentials so trust travels across platforms.

Receipt

Paid 0.5 KITE, block 22043773, delivered with an explorer link. The receipt names the generation path honestly.

Agent reputation and trust scores are computational mechanisms that enable autonomous software agents to evaluate counterparty reliability in multi-agent systems, decentralized marketplaces, and human-agent interaction platforms.

Key findings

  • Composite trust scores blend on-chain history with off-chain attestations to resist Sybil attacks.
  • Portable reputation schemas use verifiable credentials so trust travels across platforms.
  • Reputation-weighted allocation directs new tasks toward higher scoring agents.

Straight answers.

What do I need to try the live demo?

Any Kite testnet wallet with a little test KITE (chain 2368, free from the faucet). No account, no API key, no sign-up. Pick a topic, send 0.01 KITE to the seller address, paste the transaction hash, and the brief comes back with a receipt.

What happens if I pay the wrong address or too little?

The app reads the chain before delivering anything: right recipient, right amount, confirmed transaction. A wrong address, a short payment, a failed transaction, or a hash from another chain is refused with a reason. The hash is never burned, so a mistaken payment can never lock you out of retrying with the right one.

What if generation fails after I already paid?

The claim on your transaction hash is released, so you can retry with the same hash instead of paying twice. A hash is only marked redeemed once a brief has actually been delivered. Hashes never expire: each one pays out exactly once.

Which system actually wrote my brief?

The receipt says so, honestly. The paid request goes to the hiremind-seller agent through the OpenServ runtime first (SERV Reasoning). If that path is unreachable, a direct provider chain runs instead, and the receipt labels it a direct fallback, never SERV Reasoning.

Is this the full x402 facilitator flow?

It is x402 style, not the full facilitator flow. HTTP 402 answers with the price and the seller address, you pay on-chain, the app verifies the payment on-chain, then delivers. There is no off-chain facilitator in the middle. Settlement is fully on Kite testnet.

Can I reuse an old payment hash?

Only if it never paid out. Each hash delivers exactly once: a redeemed hash is refused, a failed generation releases the claim so the same hash can be retried. Age does not matter, double spend is impossible.

The cheapest due diligence you will ever put on-chain.

Pick a topic, pay 0.01 KITE, paste the hash. The brief and the receipt arrive together, usually within two minutes.
