v0.9.4

Fixed

• All example URLs migrated from legacy individual service subdomains (twitter.surf.cascade.fyi, web.surf.cascade.fyi, inference.surf.cascade.fyi) to unified surf.cascade.fyi/api/v1/ endpoints across CLI help text, README, SKILL.md, and OpenClaw plugin docs

v0.9.3

Fixed

• Solana RPC 429 rate-limit failures on concurrent payments - replaced upstream ExactSvmScheme (creates new RPC client per call) with OptimizedSvmScheme that shares a single RPC client with @solana/kit request coalescing (identical calls in the same microtask merge into one network request)
• Hardcoded USDC mint metadata (Token Program address, 6 decimals) to skip fetchMint RPC call entirely for USDC payments
• Added RPC failover transport: on 429 from one endpoint, immediately tries the next instead of failing. Two public mainnet RPCs: api.mainnet.solana.com (Solana Labs, 100 req/10s) and public.rpc.solanavibestation.com (community, 5 RPS)
• Custom RPC URL (via config or OpenClaw plugin) is tried first, with public RPCs as fallback

Changed

• Added @solana-program/compute-budget, @solana-program/token, @solana-program/token-2022, @x402/core as direct dependencies (previously transitive via @x402/svm)

v0.9.2

Changed

• Upgraded all dependencies to latest: @x402/* 2.6.0 -> 2.8.0, @solana/kit 6.3.0 -> 6.5.0, viem 2.47.6, @modelcontextprotocol/sdk 1.28.0, vitest 4.1.1, tsdown 0.21.5, @biomejs/biome 2.4.9, turbo 2.8.20, openclaw 2026.3.24
• pnpm check now runs tests alongside build, type-check, and biome
• Biome config scoped to supported file types only (*.ts, *.json, *.jsonc)

v0.9.1

Added

• setup --non-interactive flag - auto-generates wallet and outputs addresses as JSON to stdout ({"base":"0x...","tempo":"0x...","solana":"..."})
• setup --import-mnemonic flag - import existing BIP-39 mnemonic non-interactively
• MCP proxy auto-generates wallet on first run when no wallet exists (no more "No wallet configured" error)
• OpenClaw integration example in README and SKILL.md: openclaw mcp set surf '{"command":"npx","args":["-y","x402-proxy","mcp","https://surf.cascade.fyi/mcp"]}'

Fixed

• npx -y flag added to all generated MCP configs (mcp add command and docs) - prevents npx install prompt from corrupting MCP stdio protocol
• MCP config examples no longer show X402_PROXY_WALLET_MNEMONIC env var as default - wallet file is the primary path, env vars are documented as fallback only
• All example MCP URLs updated to https://surf.cascade.fyi/mcp
• Non-interactive JSON output uses network names (base, tempo, solana) instead of generic evm

v0.9.0

Added

• mcp add command - onboarding wizard to install MCP servers into Claude Code, Cursor, VS Code, and 16+ other AI clients via @getmcp/generators
• Auto-detects installed AI clients and highlights them in the selection list
• Shows config diff preview with green markers before writing
• Prompts to overwrite if server name already exists (shows current config)
• Wallet setup runs automatically if not yet configured
• Balance check and funding hints shown after successful install
• -c / --config-dir global flag to override config directory for all commands
• Custom config directory injected as XDG_CONFIG_HOME env var into generated MCP server configs
• Tempo address shown alongside Base address in setup wizard

Fixed

• Solana USDC balance shows 0 instead of ? for fresh wallets (non-existent ATA means zero balance, not unknown)
• MPP payment protocol description corrected from "streaming micropayments" to "machine payments over HTTP 402"

v0.8.6

Fixed

• Example URLs in help output and setup wizard: /user/ corrected to /users/ (was returning 404)

v0.8.5

Fixed

• OpenClaw plugin: models now appear in openclaw models list - replaced invalid models field on registerProvider() with a catalog hook returning ProviderCatalogResult, which is required by OpenClaw's provider discovery filter

v0.8.4

Fixed

• Servers returning Solana payment options with EVM-format payTo addresses (e.g. 0x...) no longer crash with a base58 decode error - malformed options are filtered out and valid options are used instead
• When all payment options from a server have mismatched address formats, a clear error is shown instead of a cryptic codec failure

v0.8.3

Added

• JSON response pretty-printing: non-streaming application/json responses auto-formatted with 2-space indent on TTY
• --json flag now works: forces JSON pretty-printing even when piped (non-TTY)
• Color-coded HTTP status lines: green for 2xx, yellow for 3xx, red for 4xx/5xx

Fixed

• MPP streaming payment label unified from MPP session: to Payment: ... MPP to match non-streaming format
• MPP streaming status line now starts on a new line instead of appending to last JSON chunk

v0.8.2

Fixed

• JSON request bodies sent without explicit Content-Type header now auto-detect as application/json instead of defaulting to text/plain - fixes servers rejecting JSON bodies on payment retry
