Proof-of-outcome infrastructure

One goal. Many APIs.
One verified outcome.

APIVouch calls independent providers, rejects broken or disagreeing results, honors cost and latency limits, and returns proof an autonomous agent can verify.

Consensus routingConstraint-boundTamper-evident receipts
Live independent proof

Three APIs. One usable truth.

Resolve the current USD→EUR reference rate across three independently operated public data origins. APIVouch requires agreement, enforces runtime constraints, and binds the result to a content-addressed receipt.

Build a trusted provider

Inspect any public OpenAPI 3.x or Swagger 2.0 contract, collect runtime evidence, and generate callable MCP tools. No API credentials are stored.

Server-owned Exhaustiveness Gate

APIVouch starts at page one and collects the evidence itself. The caller cannot submit record counts, cursors, snapshots, or page evidence.

Proof result

Run a proof to see the verdict, certificate, and bounded evidence trail.

Generated tools

Generate the agent contract to create tools.

MCP endpoint

Stateless Streamable HTTP / JSON-RPC. Read-only tools can be called immediately.

Capability boundary

Automatic live probes and generated calls are restricted to GET, HEAD, and OPTIONS. State-changing operations remain visible in the contract but return CONFIRMATION_REQUIRED; APIVouch never silently converts them to GET.
