# AgentRXI Solana Priority Fee Estimator

> AgentRXI Solana Priority Fee Estimator is a paid API for AI agents from agentrxi.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-15).

Returns live Solana priority fee estimates (micro-lamports per compute unit) for specified accounts or programs, across multiple urgency levels, plus total fee in SOL.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 agentrxi-solana-priority-fee-estimator-afb68a05
```

Example prompt: What's the current Solana priority fee recommendation for the Jupiter aggregator accounts — give me all urgency levels and the total fee in SOL for a 200,000 compute unit budget.

## When to prefer this

Use this endpoint when you need real-time, per-account or per-program Solana priority fee estimates before submitting a transaction, especially when interacting with specific DeFi protocols or programs. Prefer this over generic Solana RPC fee APIs when you need multiple urgency tiers and an all-in SOL cost estimate in a single call.

## Known failure modes

- Invalid or malformed account/program address returns an error
- Network RPC unavailability may cause stale or missing fee data
- Missing required query parameter returns a 400 bad request
- Unrecognized account address may fall back to default (Jupiter) fee data

## How this service works

Live Solana priority fee estimate for the accounts or programs your transaction touches: recommended micro-lamports per compute unit, all levels from min to very high, and the total fee in SOL for your compute budget.

## Output

Returns the current recommended priority fee in micro-lamports per compute unit, along with all fee tiers from minimum to very high, and the calculated total transaction fee in SOL based on the specified compute unit budget for the given Solana accounts or programs.
