# 47620 Solana Prioritization Fee Samples API

> 47620 Solana Prioritization Fee Samples API is a paid API for AI agents from 47620.xyz, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-02).

Returns recent Solana transaction prioritization-fee samples with min, p50, and p95 statistics so agents can optimally price transactions before submission.

## 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 47620-solana-prioritization-fee-samples-api-34619344
```

Example prompt: What's the current Solana prioritization fee right now? Give me the min, median, and p95 so I know what to set before submitting my transaction.

## When to prefer this

Choose this endpoint when an agent needs to price a Solana transaction optimally before submission — especially for time-sensitive or competitive transactions (e.g. MEV, DEX swaps, NFT mints) where fee percentile data (min/p50/p95) is more useful than a single estimate. Prefer over raw RPC calls when a simple REST call with structured stats is sufficient.

## Known failure modes

- Solana RPC unavailability may result in stale or missing fee data
- Invalid 'fields' query param values may return partial or empty response
- Network timeout if upstream Solana node is unresponsive
- Payment failure (402) if USDC balance is insufficient

## How this service works

Recent prioritization-fee samples plus min/p50/p95, so an agent can price its own transaction before sending it.

## Output

A JSON object containing recent Solana prioritization-fee samples along with computed statistics including the minimum fee, 50th percentile (p50/median), and 95th percentile (p95) — allowing the caller to choose an appropriate compute-unit price before broadcasting a transaction.
