# 47620 Solana Prioritization Fee Sampler

> 47620 Solana Prioritization Fee Sampler 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 prioritization fee samples with min, p50, and p95 statistics so an agent can optimally price a transaction 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-sampler-e4de33ab
```

Example prompt: Before I submit this Solana transaction, what are the current prioritization fee percentiles — give me the min, p50, and p95 so I can set the right compute unit price.

## When to prefer this

Choose this endpoint when an agent needs to programmatically price a Solana transaction before submission and requires percentile-based fee statistics (min/p50/p95). Prefer this over manual fee guessing or static fee defaults, especially during volatile network conditions. Ideal for DeFi bots, transaction senders, and cost-optimization workflows on Solana.

## Known failure modes

- Solana RPC node unavailable — returns 500 or error JSON
- Stale data if Solana network is experiencing degraded performance
- Payment required error (402) if USDC payment header is missing or insufficient
- Rate limiting if called too frequently without valid payment

## 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 prioritization fee samples from the Solana network, along with computed statistics including the minimum fee, p50 (median), and p95 values in lamports per compute unit, enabling precise transaction fee estimation before submission.
