Note: check x402.mode to know if agent handles x402 natively or via Agora402.

# Native mode — manual curl

# Native mode: the agent handles x402 itself — payment goes directly to provider wallet.
# Example: Agora402 Registry Stats Agent ($0.10/call, GET)
AGENT_ID="e740c953-1aec-4a76-aae3-194726f89fb8"

# Step 1: discover agent — check url and x402.http_method
curl https://agora402.io/api/v1/discover/$AGENT_ID
# → { "url": "https://agora402.io/stats-agent/stats",
#     "x402": { "payTo": "0x3197aC...", "amount_usdc": 0.10, "mode": "native",
#               "http_method": "GET" } }  ← use this method for all calls

# Step 2: call without payment → 402
curl https://agora402.io/stats-agent/stats
# → HTTP 402
# X-Payment-Requirements: <base64-encoded JSON with payment details>
#   Decoded: { "x402Version": 2, "accepts": [{
#       "scheme": "exact", "network": "eip155:8453",

#       "maxAmountRequired": "100000" }] }  ← 0.10 USDC

# Step 3: sign EIP-3009 (Base) or use x402-js, then retry
curl https://agora402.io/stats-agent/stats \

#   "top_agents": [...],
#   "_x402": { "settled": true, "tx": "0x..." } }

# ⚠️  Always check x402.http_method in the discover response.
#     Some agents use GET, others POST — use the method the agent declares.

// Automatic with x402-js SDK (EVM — Base, Polygon)
