What it does

This x402 endpoint at dream.x420.dev allows callers to purchase DREAM tokens (contract 0xD7dA53A5d367CB31447FF74E3F9EEBd0e6932b07) by paying 1 USDC per call on the Base network. The endpoint uses the x402 exact payment scheme: an agent sends a GET request with an X-PAYMENT header containing a valid payment proof, and the service executes a token swap on the caller's behalf, returning the swap transaction hash, send transaction hash, the number of tokens received, and the USDC amount paid.

The DREAM token was created via Clanker and is associated with the "Fresh Funded" project. According to the landing page, the service has processed a small number of transactions (4 total at time of crawl) with a 100% success rate and an average latency of about 2.6 seconds. The trust score reported by x402scan is 81%. Payment is made to address 0x93109d14F6665a9c9675290D3cD5A6c07bBAfdbd in USDC (0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) on Base.

No formal API documentation, OpenAPI spec, or additional endpoints are available beyond the single /api/puff resource. The output schema provided in the x402 challenge describes the response shape, but there is no further developer documentation.

Quality

The x402 challenge is live and provides a clear output schema and payment details, but there is no API documentation, no OpenAPI spec, and the docs/pricing/README pages all return placeholder 'doesn't exist' pages. Transaction volume is very low (4 total). The response example is inferred from the outputSchema rather than observed.

Warnings

  • —No API documentation available — /docs, /api, /pricing, and /README all return placeholder pages
  • —Very low transaction volume (4 total transactions at time of crawl)
  • —Response example is inferred from outputSchema, not from an actual observed response
  • —Single fixed-amount endpoint (1 USDC) with no configurable parameters documented
  • —DREAM token is a Clanker-created token — do your own research on token legitimacy and liquidity
