What it does

This x402-enabled endpoint at shiba.x420.dev allows callers to purchase a custom USDC amount worth of Shiba tokens (contract 0x0E8ef9f6355566E91B0F4903d11ae1bDE1F08b07) on Base. The token was created via Clanker and is listed on clanker.world. The site refers to the purchase action as a "Puff" — users specify a USDC amount and the endpoint executes a swap into Shiba tokens.

The endpoint is part of the x420.dev platform, which appears to host token-specific subdomains with x402 payment integration. No OpenAPI schema, formal documentation, or pricing page is available — the /docs, /api, /pricing, and /README paths all return placeholder pages. The probe did not receive a 402 challenge from the endpoint (HTTP 405 was returned instead), so the endpoint's current operational status is uncertain. Activity can be tracked via x402scan.com for the associated recipient address 0x93109d14f6665a9c9675290d3cd5a6c07bbafdbd.

Given the lack of documentation, schema, and a successful 402 challenge, this listing should be treated as a stub. Callers should verify the endpoint is live and review on-chain details before transacting.

No OpenAPI schema, no documentation, no successful 402 challenge (405 returned), and all doc/api/pricing paths are placeholder pages. The listing is effectively a stub inferred from the landing page UI and the existing title/description.

Warnings

  • —Endpoint returned HTTP 405 instead of a 402 challenge during probing — may not be operational or may require a different HTTP method.
  • —No API documentation, OpenAPI spec, or schema is available.
  • —All documentation paths (/docs, /api, /pricing, /README) return 'doesn't exist' placeholder pages.
  • —This involves purchasing a meme token — high financial risk; do your own research.
  • —Request/response examples are entirely inferred and unverified.
