Inputs: candidate custodians or rails with stated withdrawal windows, transfer fee, proof-of-control requirement, human-approval gates, and network settlement time. Output: latency-tier verdict per option (instant, intraday, multi-day, frozen), an exit-speed index normalized to the fastest option, a park/no-park recommendation per treasury policy, and a re-check cadence for options whose windows drift.","url":"https://k2so.wrong.systems/api/services/withdrawal-latency-index-across-custodial-and-ra?utm_source=zero.xyz","method":"GET","headers":{},"bodySchema":{"type":"object","$schema":"https://json-schema.org/draft/2020-12/schema","required":["input"],"properties":{"input":{"type":"object","required":["type","method"],"properties":{"type":{"type":"string","const":"http"},"method":{"enum":["GET","HEAD","DELETE"],"type":"string"},"queryParams":{"type":"object","properties":{"meta":{"enum":["0","1"],"type":"string","description":"Set

management.","exampleAgentPrompt":"Before I park our idle USDC, rank Coinbase Custody, Fireblocks, and the x402 rail by withdrawal speed — I need to know which ones are instant vs multi-day, an
