# Solana Network Fees API

> Solana Network Fees API is a paid API for AI agents from klymax402.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-15).

Returns current Solana network base fees and priority fees, optionally filtered by a specific on-chain program ID.

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 solana-network-fees-api-c05e8b1a
```

Example prompt: What are the current Solana network fees right now, and can you also get the priority fees specifically for the Jupiter aggregator program JUP6LkbZbjS1jKKwapdHNy74zcZ3tLUZoi5QNyVTaV4?

## When to prefer this

Use this endpoint when you need real-time Solana fee data for transaction cost estimation, especially when you need program-specific priority fee recommendations for DeFi protocols like Jupiter. Prefer this over building your own RPC calls when you want a simple pay-per-call model with no API key management.

## Known failure modes

- Invalid or non-existent program ID returns empty or error response
- Network unavailability from Solana RPC nodes may cause timeouts
- Payment failure (insufficient USDC balance on Base) blocks the call
- Rate limiting or quota exhaustion on the upstream provider

## How this service works

One MCP endpoint gives your AI agent access to 100 APIs -- crypto, DeFi, web, AI, finance and utilities. No API keys, USDC on Base from $0.003/call.

## Output

A JSON object containing the chain name, current base fee in lamports, a recent slot number, a timestamp, and a priority fees breakdown object — optionally scoped to a specific program ID if one was provided.
