# Solana Agent Treasury Reserve Sizing Procedure

> Solana Agent Treasury Reserve Sizing Procedure is a paid API for AI agents from k2so.wrong.systems, paid per call via x402, $0.002/call, status down (last checked 2026-10-31).

Returns a deterministic decision procedure for sizing an agent wallet's SOL/token reserve when paying via x402 on Solana, covering rent-exempt minimums, priority-fee budgets, sweep/top-up thresholds, and fee-on-transfer/freeze hazard checks.

## 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 solana-agent-treasury-reserve-sizing-procedure-d2f32a9c
```

Example prompt: What's the correct procedure for sizing my Solana agent wallet's treasury reserve for x402 payments — including rent-exempt minimums for token accounts, priority-fee budget per settlement, and how to check for fee-on-transfer or freeze hazards before committing funds?

## When to prefer this

Choose this endpoint when an AI agent needs Solana-specific treasury sizing guidance for x402 payments — particularly when EVM-generic treasury advice is insufficient, when rent-exempt account minimums and priority fees matter, or when the agent must perform fee-on-transfer/freeze hazard checks before committing funds. Prefer over generic treasury allocation endpoints when the settlement rail is Solana, not EVM.

## Known failure modes

- Missing or malformed 'input' object returns a 400-level validation error
- Payment not provided or declined results in a 402 Payment Required response with x402 payment details
- Invalid 'method' enum value (not GET/HEAD/DELETE) causes schema validation failure
- Service unavailable or provider error returns ok:false with no brief field
- Stale or cached procedure may not reflect latest Solana protocol changes

## How this service works

Paid agent-facing brief on Solana agent finance and treasury: deterministic procedure for an agent wallet paying via x402 on Solana rails to size its reserve correctly, rent-exempt minimums for token accounts, priority-fee budget per settlement, sweep and top-up thresholds, and fee-on-transfer / freeze hazard checks before committing funds. Distinct from asset-model verification (that checks what the token permits) and from generic treasury allocation (that assumes EVM).-0. Blunt decision

## Output

A JSON response containing a plain-prose decision procedure (120+ words) covering: rent-exempt SOL minimums for token accounts, priority-fee budget per x402 settlement, sweep and top-up threshold rules, and fee-on-transfer/freeze hazard checks. Also includes the topic, service slug, generation source (deterministic/llm/reasoning), and ISO-8601 timestamp of generation.
