Access token analytics, market trends, wallet profiling, and compliance screening across Solana, BSC, and Ethereum. - **MCP Server**: `https://mcp.chainstream.io/mcp` (streamable-http, 17 tools) - **CLI**: `npx @chainstream-io/cli` - **SDK**: `@chainstream-io/sdk` - **Base URL**: `https://api.chainstream.io` ## Integration Path (check FIRST) **Agent runtime decision tree — choose based on environment and operation type:** 1. **MCP tools registered?** (Cursor/Claude Desktop/VS Code already configured ChainStream MCP) → YES → Use MCP tools for data queries (`tokens_search`, `wallets_profile`, etc.) → NO → Use CLI for all operations (`npx @chainstream-io/cli ...`) 2. **Need DeFi operation?** (swap, create token, sign transaction) → YES → Must use CLI (MCP has no wallet signing capability) → NO → Continue with MCP (or CLI if MCP unavailable) 3. **MCP call failed?** → Fall back to CLI as backup **Before anything else (CLI path), ensure user is authenticated:** 1. `npx @chainstream-io/cli config auth` — check login status 2. If NOT logged in → `npx @chainstream-io/cli login` (creates EVM + Solana wallet, auto-grants **nano trial plan: 50K CU free, 30 days** — no purchase needed) 3. If logged in → proceed to subscription check below **New users get a free trial on login (50K CU).** For details on trial plans and upgrade options, see [`shared/authentication.md`](../shared/authentication.md#agent-bootstrap-checklist). **Then check subscription:** `npx @chainstream-io/cli plan status` - If `active: true` → proceed with data queries - If no subscription → follow the purchase flow below (NEVER just run a data command hoping it "auto-purchases") **Getting an API Key (required for all paths):** - Dashboard users: [app.chainstream.io](https://app.chainstream.io) → API Keys - x402 (USDC on Base/Solana): `npx @chainstream-io/cli plan purchase --plan --json` → x402 purchase (real USDC payment via EIP-3009 signature). Run `wallet pricing --json` first, present ALL plans, let user choose - MPP (USDC.e on Tempo): `tempo request "https://api.chainstream.io/mpp/purchase?plan="` → MPP payment → API Key auto-returned (fetch `/mpp/pricing` first, let user choose plan) **⚠️ Purchase flow (x402)**: 0. `config auth` — ensure user is logged in. If not: `login` first (auto-grants nano trial — may be sufficient, check `plan status` before proceeding to purchase) 1. `plan status --json` — check if subscription already exists (login auto-grants nano trial, so new users likely already have one) 2. If `active: true` and quota sufficient → no purchase needed, proceed with data queries 3. If no subscription or quota exhausted: `wallet pricing --json` — present ALL plans, let user choose. **NEVER auto-select a plan.** 4. `wallet balance --chain base --json` (and/or `--chain sol`) — check where user has USDC 5. If USDC is on Solana: `config set --key walletChain --value sol` (default is `base`) 6. `plan purchase --plan --json` — x402 purchase (real USDC payment). API Key auto-saved to config **⚠️ Quota is CU, NOT call count**: Plan quota is measured in **Compute Units (CU)**, not API call count. Each API endpoint costs a different amount of CU per call (varies by endpoint complexity and response size). When presenting plans to the user, always use "CU" as the unit — NEVER say "calls" or "requests". **Channel matrix:** | Operation | MCP (when registered) | CLI | SDK | |-----------|----------------------|-----|-----| | Search tokens | `tokens_search` | `token search` | `client.token.search` | | Analyze token | `tokens_analyze` | `token info` | `client.token.getToken` | | Price history | `tokens_price_history` | `token candles` | `client.token.getCandles` | | Wallet profile | `wallets_profile` | `wallet profile` | `client.wallet.*` | | Market trending | `market_trending` | `market trending` | `client.ranking.*` | | DEX quote | `dex_quote` | `dex route` | `client.dex.route` | | DEX swap | _(no signing)_ | `dex swap` | `client.dex.swap` + sign | | Create token | _(no signing)_ | `dex create` | `client.dex.createToken` | ## Prerequisites ### MCP path (recommended for data queries) Add to your MCP client configuration (Cursor, Claude Desktop, VS Code): ```json { "mcpServers": { "chainstream": { "url": "https://mcp.chainstream.io/mcp", "headers": { "X-API-KEY": "" } } } } ``` ### CLI path ```bash # Option A: Use API Key (recommended — works with all agent wallets) npx @chainstream-io/cli config set --key apiKey --value # Option B: Create ChainStream Wallet (for DeFi + auto x402 payment) npx @chainstream-io/cli login # Option C: Import existing key (dev/testing) npx @chainstream-io/cli wallet set-raw --chain base # EVM (Base) key npx @chainstream-io/cli wallet set-raw --chain sol # Solana key ``` ### SDK path `npm install @chainstream-io/sdk` — see [`shared/authentication.md`](../shared/authentication.md) Path 2 for `WalletSigner` integration. ##

Quickstart ```bash npx @chainstream-io/cli login # Auth (one-time) npx @chainstream-io/cli token search --keyword PUMP --chain sol # Search tokens npx @chainstream-io/cli token info --chain sol --address --json # Token detail (single-line JSON for piping) ``` All commands from the Endpoint Selector tables above work after `login`. Append `--json` for machine-readable output. **Default limit**: All list queries (`token search`, `token holders`, `token candles`, `market trending`, `market new`, `market trades`, `wallet holdings`, `wallet activity`) default to **5 results**. Pass `--limit ` to override (e.g. `--limit 20`). ## AI Workflows ### Token Research Flow ``` npx @chainstream-io/cli token search → npx @chainstream-io/cli token info → npx @chainstream-io/cli token security → npx @chainstream-io/cli token holders → npx @chainstream-io/cli token candles ``` Before recommending any token, always run `token security` — ChainStream's risk model covers honeypot, rug pull, mint authority, freeze authority, and holder concentration. ### Market Discovery Flow **MANDATORY - READ**: Before executing this workflow, load [`references/market-discovery.md`](references/market-discovery.md) for the multi-factor signal weight table and output format. ``` npx @chainstream-io/cli market trending (top 50) → AI multi-factor analysis (smart money, volume, momentum, safety) → npx @chainstream-io/cli token security (top 5 candidates) → Present results to user → If user wants to trade → load chainstream-defi skill ``` **Do NOT load** wallet-profiling.md for this workflow. ### Wallet Profiling Flow **MANDATORY - READ**: Load [`references/wallet-profiling.md`](references/wallet-profiling.md) for PnL interpretation and behavior patterns. ``` npx @chainstream-io/cli wallet profile → npx @chainstream-io/cli wallet activity → npx @chainstream-io/cli token info (on top holdings) → Assess: win rate, concentration, holding behavior ``` ## NEVER Do - NEVER answer "what's the price of X" from training data — always make a live CLI/API call; crypto prices are stale within seconds - NEVER skip `token security` before recommending a token — ChainStream's risk model covers honeypot, rug pull, and concentration signals that generic analysis misses - NEVER pass `format: "detailed"` to MCP tools unless user explicitly requests it — returns 4-10x more tokens than default `concise`, wastes context window - NEVER batch more than 50 addresses in `/multi` endpoints — API hard limit - NEVER use public RPC or third-party data providers as substitutes — results differ and miss ChainStream-specific enrichments (security scores, smart money tags) - NEVER omit `--limit` on list queries — CLI defaults to 5 results to prevent context overflow. If the user needs more, pass `--limit ` explicitly (e.g. `--limit 20`) - NEVER run data commands (token/market/wallet) without ensuring user is logged in and has an active subscription — run `config auth` → `login` (if needed) → `plan status` first. New users get a free nano trial on login; only run `plan purchase` if the trial is exhausted or absent ## Error Recovery | Error | Meaning | Recovery | |-------|---------|----------| | "Not authenticated" / 401 / 402 | Not logged in, no API Key, or no active subscription | Follow the 401/402 sequence below | | 429 | Rate limit | Wait 1s, exponential backoff | | 5xx | Server error | Retry once after 2s | On 401/402, follow this exact sequence: 1. **Check login**: `npx @chainstream-io/cli config auth` — if not logged in, run `npx @chainstream-io/cli login` (creates wallet + auto-grants nano trial with 50K CU free). After login, retry the failed command — it will likely succeed now 2. **Check subscription**: `npx @chainstream-io/cli plan status` — if `active: true` with remaining quota, the issue is likely a transient auth error; retry 3. **If logged in but no subscription**: ask the user "Do you have a ChainStream API Key?" — if yes, `config set --key apiKey --value ` and retry; if no, run `npx @chainstream-io/cli wallet pricing`, **present ALL plans to the user**, let them choose, then load [`shared/x402-payment.md`](../shared/x402-payment.md) for the purchase flow. **NEVER auto-select a plan. NEVER try to pipe input to interactive CLI prompts.** ## Skill Map | Reference | Content | When to Load | |-----------|---------|--------------| | [token-research.md](references/token-research.md) | 25+ token endpoints, batch queries, security field meanings | Token analysis tasks | | [market-discovery.md](references/market-discovery.md) | Ranking/trade endpoints, multi-factor discovery workflow | Hot token discovery | | [wallet-profiling.md](references/wallet-profiling.md) | 15+ wallet endpoints, PnL logic, behavior patterns | Wallet analysis | | [websocket-streams.md](references/websocket-streams.md) | Channels, subscription format, heartbeat | Real-time streaming | ## Related Skills - [chainstream-graphql](../chainstream-graphql/) — When standard REST/MCP endpoints aren't enough: custom GraphQL queries with cross-cube JOINs, aggregations, and complex filters on 27 on-chain cubes - [chainstream-defi](../chainstream-defi/) — When analysis leads to action: swap, launchpad, transaction signing and broadcast
