# Four surfaces. One verifiable data layer.

> PubFi product surfaces share public context, but only the installed Registry generation can establish an executable route.

Canonical HTML: https://pubfi.ai/products

## Use the surface that owns the current job

### Discovery

Compare public crypto data sources, documentation, coverage, commercial posture, and claim-safe status.

[Explore Discovery](https://pubfi.ai/discovery)

### Registry-backed API access

Inspect the live catalog and execute a selected exact route through the typed Rust gateway.

[Inspect the catalog](https://api.pubfi.ai/v1/capabilities)

### Hosted MCP

Use public capability tools, account-authenticated execution, or the separate accountless x402 endpoint.

[Open MCP discovery](https://pubfi.ai/.well-known/mcp.json)

### Custom delivery

Scope source integration, packaging, service levels, and support for a specific production program.

[Discuss custom delivery](mailto:hello@pubfi.ai?subject=PubFi%20custom%20delivery)

## Product context is not runtime availability

### Editorial pages explain fit

Product and provider pages describe public use cases and source context. They do not promise a live PubFi route.

### Registry detail proves the route contract

Current execution requires a ready capability in the installed signed generation and matching Runtime OpenAPI.

### Access stays route-specific

Free, Credit, x402, unavailable, request, and response facts belong to the exact selected capability.

## Provider product guides

These curated guides explain source fit; they are not the full API catalog. Discovery is the searchable view of every live Registry capability.

### Subscan API

Subscan API gives your app or agent a reliable way to read chain activity and account state across 70+ chains, including Polkadot, Kusama, Moonbeam, Midnight, and more, so you can ship user-facing crypto features without building core indexing first.

### DeGov API

DeGov API helps your product explain what is happening in a DAO and who is driving outcomes, making governance easier to monitor, analyze, and automate.

### Insight API

Insight API helps your users and agents catch important changes earlier by packaging live crypto narratives into streams they can monitor and act on.

### DeFi API

DeFi API gives your users clearer market visibility faster, so you can build observability features without first designing the entire data model yourself.
