What it does

This x402 endpoint allows callers to purchase x105 tokens (contract 0x51793E001bc1f58E5da3680bD1102EEE0b713B07) by spending a custom amount of USDC on the Base network. The endpoint accepts a POST request with an optional `amount` field specifying the USDC value to spend (e.g., '10', '0.5'); if omitted, it defaults to 5 USDC. The maximum payment accepted per call is 5 USDC (maxAmountRequired: 5000000 in 6-decimal USDC units). Payment is made via the x402 protocol using USDC (0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) on Base.

On success, the endpoint returns a JSON object containing a message, the swap transaction hash, the send transaction hash, the number of tokens received, and the USDC amount paid. The token was created via Clanker and is viewable on clanker.world. According to the landing page, the endpoint has a 100% success rate with an average latency of 1.28 seconds, though total transaction volume is very low (2 total transactions from 1 unique user at time of crawl).

The x420.dev platform hosts this as a subdomain-based token interaction service. Documentation pages (/docs, /api, /pricing) do not resolve, so details beyond the x402 challenge and landing page are unavailable.

The x402 challenge is live and includes a well-defined outputSchema with input/output fields. However, there is no OpenAPI spec, no documentation pages resolve, transaction volume is extremely low (2 total), and the response example had to be inferred from the schema. The endpoint is functional but sparsely documented.

Warnings

  • —Documentation pages (/docs, /api, /pricing, /README) all return 'doesn't exist' pages
  • —Very low usage: only 2 total transactions from 1 unique user at time of crawl
  • —Maximum payment per call is 5 USDC — the 'custom amount' is capped
  • —Response example is inferred from outputSchema, not from an actual observed response
  • —This involves purchasing a speculative token created via Clanker — exercise caution
