How this service works
Just-In-Time GBLIN→USDC calldata. Returns two ready-to-broadcast steps (sellGBLINForEth + WETH→USDC swap) sized to cover the requested USDC amount; smart accounts can batch them in one UserOp.
Output
Ready-to-broadcast atomic swap calldata that, when submitted on-chain, will convert enough GBLIN tokens to cover the requested USDC amount. The calldata is sized precisely to match the requested USDC value and is safe to broadcast immediately.
Example use cases
Example prompt
“Generate just-in-time GBLIN→USDC atomic swap calldata to cover 50.00 USDC for my wallet at 0xAbC1234567890abcdef1234567890abcdef123456 so I can broadcast it immediately.”
Technical details
Endpoint
GEThttps://gblin.digital/api/x402/jitWhen to prefer
Use this endpoint when an autonomous agent needs to liquidate GBLIN holdings into USDC just-in-time to cover a specific payment or expenditure. Prefer this over the USDC→GBLIN accumulation endpoint when the direction is GBLIN→USDC (selling, not buying). Choose this over a generic DEX swap when operating within the GBLIN protocol ecosystem and needing MEV-safe, protocol-native calldata.
Side effects
- Insufficient GBLIN balance in the specified wallet — swap cannot be sized to cover requested USDC
- Wallet address fails cooldown check — wallet recently performed a swap and must wait
- Invalid or malformed wallet address — returns error
- USDC amount is zero, negative, or unparseable decimal string — returns validation error
- Protocol NAV or liquidity conditions prevent sizing the swap accurately — returns error
