How this service works
EFUEL prepaid execution credit API — issue wallet-bound SML ECHO Fuel execution credits after exact canonical x402 Base/USDC settlement; $1-$100 per call, 1 USDC = 100 EFUEL, non-transferable.
Output
Returns a JSON object confirming the EFUEL credit issuance, including the number of EFUEL credits allocated (1 USDC = 100 EFUEL), wallet binding details, and settlement confirmation after the x402 Base/USDC payment is verified. Credits are non-transferable and wallet-bound.
Example use cases
Top up agent execution budget
“I need to top up my SqueezOS agent's execution budget — pay 5 USDC via x402 and get me 500 EFUEL credits issued to my wallet.”
Bootstrap new ECHO agent with credits
“I'm setting up a new SML ECHO agent and need to fund it with execution credits — settle 1 USDC through x402 and allocate the resulting EFUEL credits to my wallet.”
Verify credit issuance after payment
“I just sent a USDC payment via x402 for EFUEL credits — can you confirm the credit issuance and how many EFUEL were allocated to my wallet?”
Technical details
Endpoint
GEThttps://mcp-x402.onrender.com/gate/squeezeos/api/efuel/credits?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to programmatically purchase non-transferable EFUEL execution credits for SML ECHO or SqueezOS agent workflows using USDC via the x402 protocol. Ideal for agents that need to autonomously fund their own execution budget without manual intervention. Prefer this over generic payment APIs when the downstream system specifically requires EFUEL credits.
Side effects
- Payment amount outside $1–$100 range results in rejection
- Malformed or missing x402 payment header causes 402 Payment Required response
- USDC settlement not confirmed on-chain leads to credit issuance failure
- Wallet address missing or invalid prevents credit binding
- Service unavailable if Render.com hosting is down
