Integrating wapi into a Next.js app

wapi exposes WhatsApp over a plain REST API and is wire-compatible with WasenderAPI.

• Base URL: https://api.wapi.crafter.run
• Per-endpoint reference (generated from the server's own contract): https://api.wapi.crafter.run/docs
• Raw OpenAPI spec: https://api.wapi.crafter.run/openapi.json
• Narrative guide, with worked examples: https://wapi.crafter.run/docs

Fetch the OpenAPI spec if you need a field this skill does not cover — it is generated from the contract the server validates against, so it cannot drift from the implementation.
