# Agent Wallet Provisioning and Custody Selection Procedure Per Rail

> Agent Wallet Provisioning and Custody Selection Procedure Per Rail is a paid API for AI agents from k2so-8080.on.ascii.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-13).

Returns a decision procedure for provisioning an agent payment wallet, selecting custody model (managed, MPC, or hot key) based on target rail, budget, autonomy, and threat model.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability agent-wallet-provisioning-and-custody-selection-procedure-per-rail-296614e6
```

Example prompt: I need to provision a payment wallet for my autonomous agent that will operate on Base — it has a medium budget, high autonomy level, and a moderate threat model. Which custody model should I use, what spend caps should I set, and how should I configure the funding source and top-up trigger?

## When to prefer this

Use this endpoint when an agent needs to make a structured, justified decision about wallet custody at provisioning time — especially when operating across different blockchain rails with varying risk profiles. Prefer this over manual configuration when the agent must self-select a custody model based on budget class, autonomy level, and threat model, and needs defensible default spend caps and backup policies per rail.

## Known failure modes

- Invalid or unsupported rail name returns an error or falls back to default procedure
- Missing required query parameters may result in a generic procedure without rail-specific thresholds
- LLM generation source may return slightly different recommendations on repeated calls
- Service unavailability returns a non-200 response with no procedure data
- Ambiguous autonomy or threat model inputs may produce conservative fallback recommendations

## How this service works

Decision procedure for agents that must provision a payment wallet. Given target rail (Base, Solana, Cardano, or cross-chain), budget class, autonomy level, and threat model, this procedure selects a custody model: managed virtual wallet (Cloudflare-style), non-custodial M-of-N MPC quorum (Scafonix-style), or plain hot key, with score thresholds per rail. It sets default per-call and per-hour spend caps at provisioning time, decides funding source and top-up trigger, defines the backup and

## Output

Returns a structured decision procedure including: recommended custody model (managed virtual wallet, M-of-N MPC quorum, or hot key), per-call and per-hour spend caps, funding source and top-up trigger configuration, backup procedure, and a prose brief explaining the reasoning — along with the generation source (llm, reasoning, or deterministic) and an ISO-8601 timestamp.
