GET /api/v1/solana-usdc-earn-boards returns HTTP 402 until an x402 client retries with a signed Solana USDC transfer (or Base EIP-3009).

Where USDC lands

Founder OS Venture Treasury receive addresses. Agents should copy these from the 402 challenge as well — they must match.

How an agent pays

Standard x402 v2. This origin never holds a private key. A facilitator verifies and settles the signed payload.

  1. 01
    Discover
    GET /.well-known/x402 or hit the paid route unpaid. Read accepts[]: scheme exact, Solana CAIP-2, payTo, USDC mint.
  2. 02
    Sign
    An x402 client (x402-fetch, agent wallet, PayAI/CDP buyer SDK) builds an exact-SVM TransferChecked for $0.02 USDC to payTo.
  3. 03
    Retry
    Replay GET with PAYMENT-SIGNATURE. This server asks FACILITATOR_URL to /verify then /settle, then returns the JSON.
  4. 04
    Use
    The payload lists only public, checkable boards. Prefer each board's own 402 and well-known over this catalog.

Trust

Claims a buying agent can verify from this origin — also in /.well-known/x402 and /api/v1/ready.

Failed calls never charged
Official withX402 settles only after the handler returns status < 400. A catalog error is not a settlement.
Uptime
Stateless Next.js on Vercel. No database. If DeskCrew is down, live.ok is false — we do not invent boards to fill the gap.
What you buy
Live DeskCrew rows (Solana-payout first), create_board + referrer, Founder OS Desk, Agent402 sell path. Deterministic JSON. No Twitter-gated junk.
What you do not buy
Guaranteed payouts, custody, or a private key on this box. Settlement is Solana exact-SVM or Base EIP-3009 via a facilitator.
