Solana AI Gateway is a Zero-Trust API layer that authenticates callers with Solana wallet signatures instead of shared secrets, then meters access to a suite of “pain-killer” endpoints designed for AI agents. Instead of raw RPC data, you get processed intelligence: resolved token accounts, security-graded token profiles, congestion-aware fee tiers, and human-readable transaction summaries.

​
Why it exists

LLM agents fail on Solana for predictable reasons: they hallucinate addresses, miscalculate decimals, misread program logs, and pay the wrong priority fee. This gateway handles the plumbing server-side so the agent can focus on intent.

Wallet-based auth

Sign a challenge with your Solana wallet to claim a credit-backed API key. No passwords, no shared secrets.

Agent-ready endpoints

Processed intelligence instead of raw RPC. Address resolution, fee tiers, transaction decoding, and more.

MCP native

Ships with an MCP manifest and SSE endpoint so Claude Desktop, Cursor, and other agents discover tools automatically.

Pay per call

Pre-paid credits managed on-chain. Keys unlock only after a wallet signature proves ownership.

​
What you get

  • Cryptographic auth. Ed25519 signature verification with tweetnacl. The server never sees a password.
  • Credit-metered keys. Balances live in Postgres; the requirePayment middleware debits on each paid call.
  • Processed intelligence. ATA resolution, honeypot risk scoring, prioritization-fee tiers, transaction categorization.
  • MCP discovery. /.well-known/mcp.json and /mcp/sse let agents self-configure.
