From the repository

Add the server to your MCP client configuration with the URL https://402s.shop/api/mcp and an Authorization: Bearer ap_live_... header. Buy credits at https://402s.shop ($1 = 5 calls) or skip credits and use the x402 rail with any USDC‑funded wallet on Base. Each successful call deducts 1 credit; failed calls are not charged.

`qr_code`

Generate a QR code PNG from text or URL.

`og_image`

Generate a 1200x630 social media OG image with title + subtitle.

`screenshot`

Take a PNG screenshot of any URL using headless Chromium.

`pdf_from_url`

Render any URL to a print-ready PDF.

`word_count`

Count words and reading time on any webpage.

`extract_metadata`

Extract Open Graph, Twitter card, and standard meta tags from any URL.

`extract_emails`

Find email addresses on a webpage (mailto links + body text), deduplicated.

`website_tech`

Detect framework, CMS, analytics, and hosting/CDN of any website.

`whois`

WHOIS lookup with normalized fields (registrar, dates, nameservers, status).

`domain_check`

Check whether a domain appears available (heuristic via WHOIS, best-effort).

`youtube_transcript`

Fetch a YouTube video transcript with timestamps.

`summarize`

AI-powered summary (Claude Haiku 4.5) of supplied text or fetched URL.

`coin_price`

Crypto spot prices in USD via CoinGecko. Supports BTC, ETH, USDC, USDT, SOL, XMR, and 25+ tickers.

`ens_resolve`

Resolve ENS name to address (forward) or address to primary ENS name (reverse). Includes avatar where available.

`wallet_balance`

Native + USDC balance for an EVM address across multiple chains. Defaults to Base + Ethereum.

`gas_price`

Current gas price in gwei across EVM chains. Defaults to Base + Ethereum.

`hl_markets`

Hyperliquid perp + spot universe metadata: asset names, leverage caps, size decimals, spot tokens. Read-only proxy of /info type=meta + spotMeta. Phase 1 (read-only) — trading endpoints arrive in Phase 2.

`hl_market_orderbook`

Hyperliquid L2 orderbook snapshot (bids + asks) for a coin.

`hl_market_funding`

Hyperliquid predicted funding rates per coin per venue. Body { coin } filters to one asset; omit for full list.

`hl_market_candles`

Hyperliquid OHLCV candles. Default window: last 24h of given interval.

`hl_market_trades`

Hyperliquid recent public trades for a coin (up to ~10 most recent fills with price, size, side).

`hl_account_balance`

Hyperliquid account margin summary, withdrawable, total notional, maintenance margin used.

`hl_account_positions`

Hyperliquid open positions with size, entry price, unrealized PnL, leverage, liquidation price, cumulative funding.

`hl_account_orders`

Hyperliquid open orders for an address (oid, coin, side, limit price, size, timestamp).

`hl_account_fills`

Hyperliquid trade fills for an address (up to 2000 most recent: price, size, side, fee, closedPnl, hash).

`hl_builder_check`

Check whether a Hyperliquid main wallet has approved the 402s.shop builder code (5 bps). FREE — onboarding helper. Returns approved/maxFeeBps/sufficient flags. If not approved or insufficient, use hl_builder_approve_tx to construct an unsigned EIP-712 transaction.

`hl_builder_approve_tx`

Returns an UNSIGNED EIP-712 typed-data structure for approving the 402s.shop builder code on Hyperliquid. The agent's MAIN wallet signs locally, then POSTs { action, nonce, signature } to the returned submission_target. Server never sees main-wallet keys. FREE — onboarding helper. After approval, hl_builder_check returns sufficient=true and trading endpoints become available.

`hl_order_place`

Place an order on Hyperliquid. Phase 2: TESTNET only. Mode 1 stateless: agent signs the action client-side with @nktkas/hyperliquid SDK including the builder field {b: HL_BUILDER_ADDRESS, f: 50}, then POSTs the signed payload + agentAddress. Server validates schema, all 4 sanity guards (notional/asset/depth/post-margin), rate-limits, forwards unmodified to HL. Cloid required (16-byte hex), reused across retries for idempotency. 0.005 USDC on x402; 1 credit on Bearer.

`hl_order_cancel`

Cancel an existing Hyperliquid order by oid (numeric) or cloid (hex32). Phase 2: TESTNET only. No sanity guards (cancels reduce risk; HL handles already-canceled idempotency). 0.005 USDC on x402.

`hl_order_modify`

Modify an open Hyperliquid order — full sanity-guard suite on the new params (same rigor as place). Phase 2: TESTNET only. Action carries the replacement order entry alongside target oid/cloid. 0.005 USDC on x402.

`hl_position_close`

Close (or reduce) a Hyperliquid position via a reduceOnly=true signed order. Phase 2: TESTNET only. Server enforces reduceOnly invariant; otherwise rejects with reduce_only_required (use hl_order_place). No notional/depth/margin caps (close reduces risk). 0.01 USDC on x402.

`hl_leverage_set`

Set leverage on a Hyperliquid asset (1-50, cross or isolated). Phase 2: TESTNET only. Pragmatic margin sanity: rejects if account is currently underwater (margin ratio < 5%). HL is authoritative on per-position maintenance-margin specifics. 0.005 USDC on x402.

`hl_margin_update`

Adjust isolated-position margin on Hyperliquid. ntli > 0 adds margin (no checks); ntli < 0 withdraws margin (post-withdrawal margin ratio sanity check applies). Phase 2: TESTNET only. 0.005 USDC on x402.
