{"openapi":"3.1.0","info":{"title":"agentcash.dev","version":"0.1.0","description":"Agent payments & wallet API. Every AI agent gets its own scoped wallet and a small set of HTTP endpoints to move money on behalf of its user.","x-guidance":"Use this API to manage an agent wallet on behalf of a user, AND to participate in the on-chain presale of $PEPECUM (pepecum), a Uniswap V4 token. The token has fixed 1B supply, 9 decimals, with 50% (500M) allocated to this presale and 50% (500M) locked single-sided in V4 LP at owner-triggered openTrading(). Wallet endpoints (/v1/wallet, /v1/charges, /v1/transfers, /v1/invoices, /v1/transactions) are zero-dollar identity — sign the AgentCash Challenge to authenticate. /v1/insights/spend is a paid analytics endpoint ($0.01 USD via x402 or MPP). The /v1/presale/* family is the Ethereum mainnet presale on slot sizes {1, 10, 100} PEPECUM with per-slot pricing — each slot has its own absolute price set on-chain via Presale.price1Wei/price10Wei/price100Wei (default {0.0001, 0.001, 0.01} ETH = linear 0.0001 ETH/token): 1) POST /v1/presale/quote with { count, recipient } returns a signed quote with the slot's exact ETH price; 2) POST /v1/presale/mint returns a ready-to-broadcast tx (to/data/value/gasEstimate) for Presale.buy() — the agent broadcasts it themselves with their own wallet (msg.sender = recipient), paying msg.value AND gas atomically. msg.value auto-forwards to the treasury wallet inside the same tx; funds never sit in the Presale contract. Note: x402 v1 does not yet support Ethereum mainnet so we use calldata-return rather than 402-dance; the price range is still declared under x-payment-info so MPPScan indexes it. 3) GET /v1/presale/status reads live contract state (paused, sold, max, prices); 4) GET /v1/presale/receipt/{txHash} verifies a tx against the presale contract and returns a signed receipt. After the presale, owner calls Token.openTrading() — Uniswap V4 mainnet trading goes live with single-sided LP (no ETH paired), token starts dirt-cheap, anti-bot caps for the first 6 blocks.","contact":{"name":"agentcash.dev","url":"https://agentcash.dev"},"license":{"name":"MIT"}},"servers":[{"url":"https://api.agentcash.dev","description":"Production"}],"x-discovery":{"ownershipProofs":["dns-txt:_agentcash-discovery.agentcash.dev=acme-ownership-proof-placeholder"]},"components":{"parameters":{"IdempotencyKey":{"name":"Idempotency-Key","in":"header","required":true,"description":"Unique key per write.
