Add an "API Keys" page to the buyer SPA (marketplace.vector.apexfusion.org)
that mints a custodial gateway API key by POSTing directly to the gateway's
public /signup, then shows the key once + deposit address + a base_url/curl
usage snippet. Page lives behind the SPA's existing operator login; per-user
registration is a later feature.
Gateway:
- GATEWAY_CORS_ORIGINS env -> corsOrigins allowlist; corsMiddleware echoes
Access-Control-* only for allowlisted Origins, answers OPTIONS preflight
204, no credentials. Empty allowlist = CORS off (default safe).
Buyer:
- GATEWAY_PUBLIC_URL env -> injected into __BUYER_BOOT__.gatewayUrl (only in
the authenticated boot block). SPA resolveGatewayUrl() falls back to
deriving "api." + location.host so the post-login-no-reload case (boot
block absent) still works.
- New ApiKeys page + /api-keys route + nav link.
Deploy (mainnet compose): gateway GATEWAY_CORS_ORIGINS and buyer
GATEWAY_PUBLIC_URL set to the marketplace/api hosts. NOTE: both images must be
REBUILT (gateway runs tsx from copied source; buyer SPA is vite-built at image
build) — an env-only recreate would silently ship the old code.
Typecheck + vite build clean; 205 tests pass. Adversarial multi-agent review
(4 dimensions, per-finding verification) surfaced only the rebuild-required
deploy note above; no code/security defects.

Without VECTOR_ZERO_TIME_MS the live tx builder defaults to the testnet genesis,
placing PostEscrow validity bounds ~51 days in the future (Ogmios 3118). Escrow
spends (Accept/Reclaim) also need ESCROW_REF_UTXO. Mirror buyer/supplier mainnet env.

New multi-tenant gateway package: external developers point any OpenAI SDK at
the marketplace. Each API key is its own custodial buyer wallet (AES-256-GCM
sealed under GATEWAY_MASTER_KEY); every request posts an on-chain escrow from
that user's wallet.
- POST /openai/v1/chat/completions (one escrow/call, llm.text.generate.v1,
buffered + pseudo-stream), chat sessions (one escrow/session, llm.chat.v1,
real SSE), GET /openai/v1/models, /signup, /account, /account/withdraw.
- Settles by resolving the Submitted ref via the indexer + awaited Accept;
state-aware reclaim sweeper + per-wallet auto-consolidation for collateral.
- Reuses the buyer Marketplace SDK via new buyer exports ./sdk; new shared
buildWithdrawTx (custodial exit). Runs via tsx; Dockerfile + mainnet compose.
Design in docs/gateway.md. Typecheck passes for all packages; 20 vitest tests
pass. Not yet exercised against a live chain.
