Live Demo: This Val Called Itself as an API

\n Right now, while rendering this page, the server called its own JSON endpoint (?format=json),\n fetched structured data, and embedded it below. This is val composability in action.\n

Live API Response (fetched server-side, just now)

${apiError ? \"Error: \" + apiError : JSON.stringify(apiData, null, 2)}

\n\n

The Pattern: Val-to-Val Composition

Build microservices that compose naturally. Each val is an independent endpoint that other vals can call.

What This Unlocks for Portfolio Companies

Instant APIs

Deploy a data endpoint in seconds. Your mobile app calls it immediately.

Scheduled Jobs

Run a val on a cron schedule — daily digests, weekly reports, nightly syncs.

Webhook Processors

Receive Stripe, Twilio, or GitHub webhooks without standing up a server.

AI Pipelines

Chain vals together: ingest data → call OpenAI → store result → notify Slack.
