Three moves to first token.

01
Connect & sign
Your wallet is your account. A single SIWE signature opens the console — no gas, no forms.
02
Top up in USDC
Send native USDC on Base, Arbitrum, or any supported chain. The deposit is confirmed on-chain and credited to your balance.
03
Point & ship
Mint a relay key, set the base URL, and call any model. Usage is metered per token.
surface

Built for the people who ship.

⊹
OpenAI & Anthropic native
Keep your SDK or agent. Claude Code, Codex, OpenClaw, Cursor — all point at one base URL and a key.
◈
Wallet login (SIWE)
No email, no password. Your wallet signs in. Sign a message, get a session — zero gas.
₮
Multichain USDC settlement
Top up in native USDC on Base, Arbitrum, OP, Avalanche or Ethereum. Deposits are confirmed on-chain and credited to your balance.
≣
Cache-aware metering
Metered per token in integer USDC units — and cached tokens bill at the cheaper cache-read rate.
⟂
Streaming, untouched
SSE passes straight through with backpressure. Tokens arrive the instant the model emits them.
◇
Text, image & video
Chat and embeddings, plus image generation (incl. image-to-image) and video — every modality, one key.

Keep your stack.

If it speaks OpenAI or Anthropic, it speaks DeFAI Relay. Point an OpenAI client at https://defai.gtio.work/v1 — or Claude Code at https://defai.gtio.work — and use your relay key. Streaming, tools, and usage all work the way you expect.

curl https://defai.gtio.work/v1/chat/completions \
  -H "Authorization: Bearer sk-relay-…" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "anthropic/claude-opus-4.8",
    "messages": [{"role":"user","content":"Settle this."}],
    "stream": true
  }'

Point your stack at one endpoint.

Wallet-native. OpenAI + Anthropic. Settled in USDC.
