Epsilon

Overview

Epsilon offers limit, stop-loss, DCA and trailing orders for memecoins and RWAs on Robinhood Chain, executed from the user's own wallet (https://www.epsilon.exchange). The developer platform documents a REST API at https://api.epsilon.exchange/v1, the SDKs @epsilon-exchange/sdk (npm) and epsilon-exchange (PyPI), a CLI, webhooks and an MCP package @epsilon-exchange/mcp with a hosted endpoint (https://developers.epsilon.exchange). Orders are EIP-712 messages signed locally. API keys (eps_…) were issued through a concierge during early access, with self-serve issuance described as planned. The MIT-licensed plugin repo bundles a 12-tool MCP server and two agent skills, with a per-order USD cap and a confirmation gate on by default (https://github.com/alienbase-xyz/epsilon-plugin).

Tool inventory — 22 tools, probed live 2026-11-07

• cancel_order — Ask the user to approve cancelling one of their open orders (hash from list_orders). Returns an approval link; the cancellation is signed by the user's wallet in the Epsilon app. Orders already filled
• check_order — Check whether a resting order (limit, stop, DCA, trailing) for this pair and size would be executable: oracle support, liquidity, minimum size. Run this before signing any resting order; it does not p
• get_approval — Status of an approval you created: pending (user hasn't decided), submitted (with orderHash or txHash — then use get_order to follow fills), rejected, failed, or expired (links live 30 minutes). Poll
• get_error_catalog — Machine-readable catalog of every error code the Epsilon API returns, with meanings and retry guidance. Consult it when any other tool returns an error code you need to interpret or decide whether to
• get_example — Full source code of one Epsilon integration example, by id from list_examples. No API key required.
• get_grant — The signed-in account's agent grant for this channel, if any: the embedded wallet it signs with, per-order and daily caps, what remains today, allowed order kinds, and whether the Epsilon signer is ac
• get_market_stats — Market-level numbers for Epsilon (Robinhood Chain DEX). scope=overview (default) is the best first call: top tokens by 30-day volume, 24h volume, and engine-wide order/fill stats in one response. scop
• get_me — The signed-in Epsilon account behind this session: account id, handle, linked wallets (embedded first), the scopes this client was granted, and which client is connected. Call it first after sign-in t
• get_order — One Epsilon order by hash: status (pending/active/filled/cancelled/expired), parameters, and its fills. Use list_orders to find orders by wallet first; use get_orderbook for the market's resting order
• get_orderbook — The market's open (pending/active) limit orders on both sides of a token pair, largest first — liquidity you can rest against. For one wallet's own orders use list_orders instead.
• get_quote — Best executable quote for swapping tokenIn → tokenOut on Epsilon (Robinhood Chain, id 4663): expected output and price. Use this for a quick price check; use get_route when you need the venue split, f
• get_route — Full routing breakdown for a swap: best venue split, expected and minimum output, price impact (ppm), and the feeLegs a signed order must embed (pass orderType for a resting order so the right fee cel
• list_examples — List runnable Epsilon integration examples (Python cron DCA, LangChain tools, Vercel AI SDK tools, Telegram bot). Fetch full source with get_example. No API key required.
• list_fills — Executed trades (swaps and order fills) on Epsilon, newest first, optionally for one wallet — the trade history. For resting/open orders use list_orders. Amounts are RAW token units.
• list_orders — A wallet's Epsilon orders filtered by status and/or type — the portfolio view, newest first. Use get_order for one order's fills; use list_fills for executed trades.
• place_dca_order — Ask the user to approve a DCA program: sell amount of tokenIn for tokenOut in `executions` equal slices, one every `every` (15m, 1h, 1d…). Optionally gated by triggerPrice (only sells at or below it).
• place_limit_order — Place a resting limit order: sell amount tokenIn for tokenOut once the market reaches limitPrice (tokenOut per tokenIn) or better. Keeper-executed — it keeps working with the chat closed. If the user
• place_market_order — Ask the user to approve a market swap of amount tokenIn → tokenOut at the best current route. Returns an approval link, not a fill: the user signs in the Epsilon app. Use get_quote first to tell the u
• place_stop_order — Place a stop-loss: sell amount tokenIn for tokenOut if the price falls to triggerPrice (tokenOut per tokenIn). Keeper-executed. Queued under an active agent grant that covers it, otherwise returns an
• place_trailing_order — Ask the user to approve a trailing stop: sell amount tokenIn for tokenOut when price drops trailPercent below its running high since placement. Keeper-executed after signing; always returns an approva
• search_docs — Search the Epsilon developer documentation (API, auth, order signing, webhooks, rev-share, SDKs, MCP). Returns the most relevant doc sections. No API key required.
• search_tokens — Resolve a token symbol or name to its address and decimals — call this FIRST when the user names a token; every other tool takes addresses. volume30dUsd disambiguates same-symbol tokens: the real one

Answers a call

yes — get_error_catalog returned in 188 ms

Live probe verifies the interface responds — not what the tools do, their safety, or their output quality. The call is one read-only tool named by this server's own list (list_/get_/search_, no mutating verb anywhere in the name, no required arguments and none that look like a key, an address or an amount), asked once a day with no arguments. Not asked is not a failure.
