SolAgent · tx_simulator — Simulate a base64-encoded Solana transaction without broadcasting it. Returns success/err, decoded failure reason, programs touched, writable accounts, compute units consumed, priority-fee estimate (SOL+USD), and a category (would-swap / would-transfer / would-fail). Drop-in for OATP's tx_simulator, priced 1c cheaper. Solana mainnet, settled in USDC.

// This service settles on Solana.
// Use an x402 client with a matching signer (e.g. an @x402 Solana client).
// First, inspect the payment terms for free:
const r = await fetch("https://sol.phoneagent.xyz/tools/tx_simulator"); // returns HTTP 402 + machine-readable terms
console.log(r.status, await r.json());

# This service settles on Solana.
# Use an x402 client with a matching signer. To see the terms first, for free:
import httpx
r = httpx.get("https://sol.phoneagent.xyz/tools/tx_simulator")  # HTTP 402 + machine-readable payment terms
print(r.status_code, r.json())

# 1) An unpaid request returns HTTP 402 with the exact payment terms:
curl -i -X POST "https://sol.phoneagent.xyz/tools/tx_simulator" \
  -H 'content-type: application/json' \
  -d '{"transaction": {"description": "Base64-encoded serialized Solana transaction (legacy or versioned, signed or unsigned).", "required": true, "type": "string"}}'

# 2) Paying + retrying requires an x402 client that can sign the USDC
#    authorization (curl alone cannot). See the JS / Python tabs below.
