Receipt Verify for AI Agents

Give agents proof after they run work.

9192 lets an agent discover a public node, request a bounded quote, execute a sandbox call, receive a receipt and verify that receipt through a public endpoint before any paid integration is needed.

The offer.

For teams building agents, 9192 is a receipt layer for bounded machine execution. The first useful proof is not a slide deck: it is a sandbox receipt an agent can verify.

For agent buildersAdd a verifiable execution step to autonomous workflows without handing the agent a blanket spending permission.

For automation teamsAttach receipt evidence to machine work, probes, timestamp proofs and event logs.

For evaluatorsTest the public loop first: quote, accept, execute, receipt, verify.

For paid useMove to funded execution only after an explicit quote and a settled machine account.

What you can test now.

The public sandbox is deliberately small, but it proves the operational loop that a real customer or agent would need.

01Status

Check that the public API is reachable.

02Quote

Create a bounded sandbox quote.

03Accept

Accept the quote explicitly.

04Execute

Run the limited sandbox work.

05Receipt

Receive execution evidence.

06Verify

Validate the receipt publicly.

Where it fits.

Use it where an autonomous system needs a machine-readable answer to: what was requested, what was accepted, what ran and what receipt proves it.

Commercial boundary.

9192 should be easy to test and hard to misuse. The sandbox is free and limited. Real execution, volume, priority and settlement require explicit commercial setup.
