# Coinlight Solana Priority Fees

> Coinlight Solana Priority Fees is a paid API for AI agents from coinlight-app.vercel.app, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-29).

Returns recent Solana network prioritization fees as p25/p50/p75/p90 percentile estimates in micro-lamports per compute unit, optionally scoped to a specific account.

## 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 coinlight-solana-priority-fees-03f6e274
```

Example prompt: What's the current Solana priority fee estimate — give me the p25, p50, p75, and p90 levels in micro-lamports per compute unit so I can set the right fee for my transaction to land.

## When to prefer this

Use this endpoint when you need to price a Solana transaction to ensure it lands — especially before submitting swaps, mints, or other time-sensitive on-chain actions. Prefer this over generic RPC calls when you want pre-bucketed percentile statistics (p25/p50/p75/p90) without parsing raw fee history yourself. Ideal for agents that need a quick, structured fee recommendation scoped to a specific program or pool.

## Known failure modes

- RPC data unavailable or stale — may return an error or empty fee data
- Invalid account address format — malformed base58 address returns an error
- Network timeout fetching on-chain fee data
- Payment not included or insufficient — x402 payment required before data is returned

## How this service works

Coinlight charges USDC per API call with the x402 protocol on Solana and Base.

## Output

A JSON object containing recent Solana prioritization fee estimates at p25, p50, p75, and p90 percentiles, expressed in micro-lamports per compute unit, reflecting real recent network conditions. Optionally scoped to a specific writable account such as a pool or program.
