  payment_gate: x402 (HTTP 402) on 10 REST doors and 4 MCP tools — an economic gate, not an authentication scheme
  note: >-
    The public surface needs no credential of any kind. api-docs: "Public · keyless · CORS-open … No account, no
    API key, no tiers … Auth: none." 92 of 141 operations declare security [] and a further 44 declare no
    security block; every read of the board, the signed cards, the root and the proofs is anonymous, as are MCP
    initialize/tools/list and the A2A JSON-RPC endpoint. The three declared securitySchemes guard
    provider-internal action-job and canary doors only (5 operations): there is no public sign-up that yields one of them. Paid
    artefacts are unlocked by an x402 payment (X-PAYMENT header on REST, x_payment argument on MCP), settled by
    the caller's own wallet in USDC on Base; the provider "holds no key for you and never settles on your
    behalf" (quickstart.json step 4).
