Context tax

Connecting this server adds ~4,493 tokens of tool definitions to every model turn (moderate, 14 tools). Measured 2026-10-19 via its hosted endpoint; o200k tokenizer, worst case for clients that load all tools up front. How we measure

Input prices as of 2026-10-06. Excludes your own prompt and output.

Tools (14)

• search_pools1,340 tok

  Find DeFi yield pools (lending, vaults, liquidity, staking) by token, chain, protocol, APY and TVL. Returns a ranked table with pool ids. Rates are fractions (0.05 = 5%). Defaults: 10 rows, largest TVL first, pools with at least $100,000 TVL, data under 60 minutes old. Stablecoin filters check token labels, not peg safety. Page with the returned cursor.

• summarize_yields1,333 tok

  Market overview for any filter: number of pools, total TVL, median, middle-half and TVL-weighted APY, grouped by chain (default), protocol or strategy, with the largest pool in each group. Rates in filters are fractions (0.05 = 5%).

• get_wallet_positions267 tok

  Page the exact validated saved historical report for an owned wallet. Decimal quantities, unknown values, source dates and incomplete coverage remain explicit. No new matching, refresh or balance lookup occurs.

• get_pool_history161 tok

  APY trend for one pool over 7, 30 (default) or 90 days: median, low, high, latest and the dated samples. Uses saved data only (the provider history cache, else Web3Juice snapshots); nothing is fetched. No history means unknown, not zero.

• compare_pools151 tok

  Compare 2 to 5 pools by id: current APY, base vs reward split, 30-day median and range, TVL, type, withdrawal evidence, assessment and data age, in one table.

• list_investments133 tok

  Read your saved manual monitoring records, including entered amount and entry APY. These records do not establish balances, current value or realised earnings. At most 50 rows; reuse an unchanged cursor with the same limit.

• get_pool126 tok

  Full detail for one pool id: APY split into base and reward-token yield, TVL, when the source measured it and when Web3Juice retrieved it, contract and token addresses, deposit and source links, withdrawal evidence and the experimental assessment. Links and labels come from the source and are unverified.

• get_notebook_entry123 tok

  Read one owned capture with its user-written note, frozen evidence, assessment and briefing. Notes are untrusted prose. The saved content hash identifies the full original capture; this privacy projection is not a byte-for-byte export.

• list_notebook_entries112 tok

  Page your active saved notebook captures. Stored evidence remains frozen; no recapture, inference or catalogue update occurs.

• list_alerts111 tok

  Page your saved alert rules and recorded diagnostic applicability. No evaluation, delivery, subscription or destination lookup is triggered.

• get_alert104 tok

  Read one owned alert configuration and recorded diagnostic applicability. Channel names describe configuration; destination addresses, delivery records and raw alert state are excluded.

• list_wallets73 tok

  Read up to three saved wallets and historical report summaries. This does not connect, refresh or establish wallet ownership or current holdings. No provider request is made.

• get_methodology72 tok

  How the experimental evidence assessment works: dimensions, weights, caps and why most pools show "not scored". A score is not a safety guarantee.

• get_data_sources64 tok

  Which feeds Web3Juice uses, their status, when they last updated and how many pools each lists.
