radius-sdk@0.4.0

Minor Changes

• bdd6d76: Accept payments from any HTTP stack, not just Hono. New radius-sdk/server entry point:

  • radiusPayments() is a web-standard handler (Request in, Response out) for Cloudflare Workers without a framework, Bun, Deno, Node 18+, and Next.js / SvelteKit / Remix route handlers. Paid handlers receive the settled receipt as a second argument.
  • createRadiusServer() exposes the Radius x402 resource server and a routes() builder that plug straight into the upstream adapters: paymentMiddleware(radius.routes({ … }), radius.server) with @x402/express, @x402/next or @x402/hono.
  • onSettled is registered on the resource server, so it fires whichever adapter served the request (it receives the x402 request context; requestOf(context) returns the Request for the SDK's own adapters). Errors thrown by onSettled are logged by x402 core instead of failing the request.
  • Paid responses stream through in the default settle: 'before' flow instead of being buffered (the previous Hono middleware buffered every paid response, stalling SSE and token streams).
  • Breaking: radius-sdk/hono is now a thin wrapper over the web-standard handler with the same options. RadiusHonoAdapter is removed; RequestAdapter from radius-sdk/server (an x402 HTTPAdapter over a web-standard Request) replaces it.
  • @x402/core / @x402/evm bumped to 2.27.0 (the version line the upstream adapters require).
  • New examples: examples/worker-plain (no framework), examples/express-seller (@x402/express) and examples/astro-seller (validate before charging in an Astro API route).

Patch Changes

• 23f73d6: radiusPayments accepts facilitators that list the eip3009 transfer method for exact. Previously every paid route answered 500 once the facilitator's /supported named eip3009 before permit2.
• 5a915b2: radiusPayments answers 502 (facilitator_error) when a facilitator call fails without the facilitator's own answer, such as a dropped connection or an error page from a gateway. These were reported as 402, which a buyer reads as "rejected, nothing moved", although a settle may have reached the chain. The facilitator's own rejections are still 402.
