{"service":"spiralstake","display_name":"SpiralStake","version":"0.1.0","description":"SpiralStake is an x402 micropayment gateway to Spiral Stake's non-custodial leverage execution layer on Morpho. It exposes the same seven tools as the Spiral Stake MCP server as plain HTTP endpoints, payable in USDC or EURC through the x402 two-round HTTP 402 handshake via the central facilitator. An agent reads live strategies, prices, and on-chain positions; runs a deterministic simulation of a leveraged position with no wallet; then builds an unsigned transaction bundle that a human reviews and signs locally. It serves two profiles: Leveraged Yield on correlated pairs, where leverage multiplies the spread between collateral yield and the borrow rate, and Leveraged Long on non-correlated pairs for directional exposure without selling the base asset. Positions are non-custodial and isolated per user, each in its own UserProxy clone; the gateway never holds or touches a private key. Contracts were audited by three independent firms.","archetype":"function-toolkit","maturity":"beta","tags":["leveraged-yield","morpho","non-custodial-leverage","defi","flash-loans","x402","micropayments"],"networks":[{"name":"Base","chain_id":"eip155:8453","asset":"USDC/EURC"},{"name":"Arbitrum","chain_id":"eip155:42161","asset":"USDC"},{"name":"Polygon","chain_id":"eip155:137","asset":"USDC"},{"name":"Avalanche","chain_id":"eip155:43114","asset":"USDC"},{"name":"Ethereum","chain_id":"eip155:1","asset":"USDC"}],"accepted_assets":["USDC","EURC"],"facilitators":["https://facilitator.x402.press"],"payment_scheme":"exact","persona":"/persona","operations":2,"pricing":{"/v1/build/leverage-tx":{"Base USDC/EURC":"$0.006125","Arbitrum USDC":"$0.00525","Polygon USDC":"$0.004375","Avalanche USDC":"$0.00175","Ethereum USDC":"$2.625"},"/v1/build/manage-tx":{"Base USDC/EURC":"$0.006125","Arbitrum USDC":"$0.00525","Polygon USDC":"$0.004375","Avalanche USDC":"$0.00175","Ethereum USDC":"$2.625"}}}
