# Solana Agent Payment Fee and Compute Budget Procedure

> Solana Agent Payment Fee and Compute Budget Procedure is a paid API for AI agents from k2so.wrong.systems, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-14).

Returns a machine-readable decision procedure for sizing Solana priority fees and compute unit limits for agent payment transactions, with a pass/fail verdict and fee+CU budget tuple.

## 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-payment-fee-and-compute-budget-procedure-925bb855
```

Example prompt: Give me the recommended priority fee and compute unit budget I should use for my Solana agent payment transaction right now, including how many slots to wait before retrying if it doesn't confirm.

## When to prefer this

Choose this endpoint when an AI agent needs a deterministic, machine-readable procedure for sizing Solana priority fees and compute unit limits before submitting a payment transaction — especially when avoiding congestion failures, late landings, or fee overpayment is critical. Prefer this over generic Solana RPC fee estimation when you need structured retry logic and a pass/fail verdict rather than raw fee data.

## Known failure modes

- Payment of 0.002 USDC not made — returns 402 payment required with no procedure
- Invalid query parameters return schema validation error
- Service unavailable or provider downtime returns 5xx with no procedure data
- Stale block fee data may produce outdated fee recommendations
- Topic override not recognized may yield generic rather than targeted procedure

## How this service works

Pay 0.002 USDC on Base for a machine-readable procedure that budgets Solana priority fees and compute unit limits for agent payment transactions, so a payment lands in the right slot instead of failing on congestion or overpaying. Covers priority fee sampling from recent blocks, CU limit sizing per instruction set, the failed-transaction vs landed-late failure modes, and the retry threshold when a payment does not confirm in N slots. Returns a pass/fail verdict with the fee and CU budget tuple.

## Output

A structured response containing a pass/fail verdict, a recommended priority fee value, a compute unit limit sized to the instruction set, decision procedure prose explaining the rationale, the generation source (llm/reasoning/deterministic), and an ISO-8601 timestamp. Optionally includes payment confirmation metadata.
