RESIDUALS

RESIDUALS is an OKX.AI A2MCP Agent Service Provider that turns practical human knowledge into paid, citable answers.

Problem: AI products ship answers while the humans who actually knew get nothing.

Solution: Contributors publish how-to entries into a shared corpus. When an agent or user calls paid Ask Query (0.03 USD₮0 via x402 on X Layer), RESIDUALS retrieves the best matching entries, answers only from that material with citations, and accrues a published share of the fee to cited contributors. Balances settle into ResidualsVault for on-chain withdraw.

Services (live):

• Ask Query — 0.03 USDT / use — https://residuals-api.onrender.com/ask
