Hive turns every AI inference, agent action, model call, and agent payment into an AI receipt: an independently signed, portable object that anyone can check offline. It's the proof layer under agent receipts, signed model calls, x402 AI payments, MCP and API agent receipts, and a full AI audit trail. Every receipt carries two signatures, Ed25519 and post-quantum ML-DSA-65 (NIST FIPS 204).
Each phrase below points to the same idea: independent, signed proof of AI behavior. Follow any thread to the live page or explainer behind it.
Signed, independently verifiable proof of what an AI system did. The base object: dual-signed, portable, offline-verifiable, and post-quantum under ML-DSA-65.
Cryptographic AI receipts → Thread 02Every route decision, tool call, model choice, and action an AI agent takes, captured as a signed receipt chain: verifiable proof of what an autonomous agent actually did.
Agent receipts, live → Thread 03Agents pay per action in USDC on Base through the HTTP 402 payment_required flow. Settlement is live today, and every payment emits a signed receipt.
x402 checkout → Thread 04A signed receipt for each agent payment: what was paid, for which action, on which rail. It's settlement proof that outlives the transaction.
Emit a payment receipt → Thread 05Independently check the signature on a model call: provider, model, prompt hash, response hash, timing. Hive checks it in your browser and offline.
Verify a model receipt → Thread 06Which agent, which tool, which model, which human: each one bound as a signed field, so proof of origin survives after an artifact leaves your systems.
Verify surface → Thread 07The chain of signed receipts an AI system leaves behind, assembled into an exportable, independently re-verifiable record for an auditor, partner, or regulator.
Assurance postures → Thread 08Post-quantum ML-DSA-65 (NIST FIPS 204) signatures over AI inference, agent actions, and human-origin data, checkable offline by anyone.
The cryptography → Thread 09Agents whose every action is receipted by default. Choose the agent, the receipt level, the fleet size, and run: from one agent to a hundred.
Agent fleet → Thread 10Prompt through Hive to a model and get the response plus a signed receipt for the call path. Mistral Leanstral is live today; the adapter layer targets more providers.
Signed model calls → Thread 11Each action an AI takes, a route, a tool call, a decision, gets minted as a real ML-DSA-65 receipt and checked right in your browser.
Watch actions receipt → Thread 12On-rail proof that an agent paid for what it used: x402 settlement in USDC on Base, with each task receipted. Usage you can prove, not just a bill you have to trust.
Agent payment proof → Thread 13When an MCP-compatible agent operates a platform through its tools, each operation becomes a signed receipt: which agent, which tool, against which workspace.
Receipt every agent operation → Thread 14Every API operation an agent performs, each model, tool, and approval stop on the route graph, gets captured as a signed route receipt.
SmartAgent route graph →Every page below is real and running, not a mock. Start with a free model receipt, pay and prove with x402, or run an agent trip.
Here's the receipted money-movement loop: Receipt Relay signs the event, Hive Ledger searches, exports, and checks it, and Payment Healing sorts out rail-specific recovery. Hive proves what happened early enough to act on it where the rail allows, and proves what happened after the fact when it doesn't. The Circle/USDC-compatible receipt schema is live today. Direct Circle integration comes next.
This hits Hive’s public, no-login x402 quote endpoint and returns a live settlement envelope with an ML-DSA-65 (FIPS 204) signed quote receipt. No key, no secret, nothing to install.
