Common questions
Is X402 Solana safe?
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed –, and the latest version (0.1.0) reached the registry 4 months ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.
What can I use instead?

x402-solana
Paid x402 API tools for AI agents, settled in USDC on Solana (mainnet). A Solana-rail replica of x402-endpoints (Base): same FastAPI quality, same CDP facilitator — payments routed on Solana instead of Base.
- No API key — payment is authentication.
- Gasless for the buyer — the CDP facilitator is the transaction fee payer.
- USDC mint

Deploy (Render)
One-click via render.yaml (Blueprint). Set the sync:false secrets (CDP_API_KEY_ID, CDP_API_KEY_SECRET, RECEIPT_SIGNING_SEED, optional ANTHROPIC_API_KEY) in the dashboard.
Architecture
Payment layer is 100% in app/main.py (register_exact_svm_server + PaymentOption(network=solana…)); endpoint handlers in app/routers/ are payment-agnostic. Description ≤ 500 chars is enforced at startup (hard CDP /verify constraint). See DIFFERENCES-BASE-SOLANA.md for the full Base→Solana map.
Tooling (tools/)
check_facilitator.py— verify the CDP facilitator advertises Solana support.lint_descriptions.py— English-only + ≤500-char lint.gen_discovery.py— regenerate the discovery files from the routes.create_seller_ata.py— create the seller USDC ATA (settlement prerequisite).settle.py— buyer→endpoint settlement (dry by default,--executeto pay).
