What it does

The dir.x420.dev /api/puff endpoint is an x402-enabled service that accepts a 1 USDC payment (on Base network) and automatically swaps it for DIR tokens (contract 0x78e2bABb02BAECeA3449fA3Bea7b190B2e49DB07), returning the purchased tokens to the caller. DIR is a token created via Clanker and traded on Base.

The endpoint uses the x402 payment protocol (version 1, "exact" scheme). When called without payment, it returns a 402 challenge specifying the USDC asset address (0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) and a payTo address. Once the X-PAYMENT header is provided with a valid payment proof, the service executes a swap and sends the resulting DIR tokens. The response includes the swap transaction hash, send transaction hash, the amount of tokens received, and the USDC amount paid.

The landing page at dir.x420.dev shows x402 stats including a 100% success rate, average latency of 2.69s, a trust score of 85%, and 5 total transactions from 5 unique users. No formal API documentation, OpenAPI spec, or pricing page exists beyond the x402 challenge itself and the landing page.

The endpoint is live with a valid 402 challenge and includes an outputSchema describing the response. However, there is no OpenAPI spec, no formal documentation (docs/api/pricing pages all return 'doesn't exist'), and the service is very niche with only 5 total transactions. The response example is inferred from the outputSchema rather than directly observed.

Warnings

  • —No API documentation exists — /docs, /api, /pricing, and /README all return placeholder pages
  • —Very low transaction volume (5 total transactions) suggests early-stage or experimental service
  • —Fixed 1 USDC payment amount — no variable amount support documented
  • —DIR token is a Clanker-created token with unknown liquidity and risk profile
  • —Response example is inferred from outputSchema, not from an actual observed response
