## Tools (18)

- `base_gas_price`: Current Base mainnet gas price read live from JSON-RPC, in both wei and gwei. Use this to estimate the cost of a Base transaction before submitting it. Costs $0.005 USDC per call via x402 on Base; an unpaid call returns the payment challenge instead of data, and a call that returns no data is never settled so it costs nothing. Equivalent HTTP route: GET /gas.
- `crypto_spot_prices`: Coinbase spot price in USD for up to ten crypto assets. Use this for a current crypto price. Returns an explicit per-symbol error rather than a guessed number when an asset is unavailable. Costs $0.005 USDC per call via x402 on Base; an unpaid call returns the payment challenge instead of data, and a call that returns no data is never settled so it costs nothing. Equivalent HTTP route: GET /crypto.
- `defi_chains`: Total value locked per blockchain from DefiLlama, ranked high to low, with each chain's native token symbol and EVM chain id plus the summed cross-chain total. Use it to compare chains by capital deployed or to check where a chain sits. A chain with no published TVL keeps a null figure and is excluded from the total rather than counted as zero. Costs $0.005 USDC per call via x402 on Base; an unpaid call returns the payment challenge instead of data, and a call that returns no data is never settled so it costs nothing. Equivalent HTTP route: GET /defi/chains.
- `defi_protocol`: Full DefiLlama detail for one protocol by slug: current TVL in USD with its observation time, per-chain TVL breakdown, category, token symbol, chain list, description and links. Use it after finding a slug with the protocols list. An unknown slug returns an honest not_found and is not billed. Costs $0.005 USDC per call via x402 on Base; an unpaid call returns the payment challenge instead of data, and a call that returns no data is never settled so it costs nothing. Equivalent HTTP route: GET /defi/protocol.
- `defi_protocols`: Rank DeFi protocols by total value locked from DefiLlama, filtered by chain, category or name substring, with each protocol's slug, category, chain list, TVL in USD, 1d/7d TVL change and market cap. Use it to size a protocol, find the biggest venues on a chain, or resolve the slug the protocol-detail tool needs. A protocol DefiLlama publishes no TVL for keeps a null figure, never a zero. Read live at request time and held for 5 minutes. Costs $0.008 USDC per call via x402 on Base; an unpaid call returns the payment challenge instead of data, and a call that returns no data is never settled so it costs nothing. Equivalent HTTP route: GET /defi/protocols.
- `defi_token_prices`: Price arbitrary on-chain tokens with DefiLlama's coins API, addressed as chain:address (or coingecko:id), returning price in USD, symbol, decimals, a confidence score and the pricing timestamp for each. Use it to value a DeFi position holding tokens no exchange lists. This is NOT the exchange spot-price tool: use the crypto spot tool for a plain price of a major asset. A token DefiLlama cannot price inside search_width returns null, never a substituted price. Costs $0.005 USDC per call via x402 on Base; an unpaid call returns the payment challenge instead of data, and a call that returns no data is never settled so it costs nothing. Equivalent HTTP route: GET /defi/token-prices.
- `defi_yields`: Screen DefiLlama's yield-pool universe by chain, project, token symbol, minimum TVL and stablecoin-only, ranked by APY, returning each pool's stable pool_id, chain, project, symbol, TVL in USD, total/base/reward APY, 30-day mean APY, impermanent-loss risk and exposure. Use it to find where a given asset earns yield. An unpublished APY stays null, never zero. Costs $0.008 USDC per call via x402 on Base; an unpaid call returns the payment challenge instead of data, and a call that returns no data is never settled so it costs nothing. Equivalent HTTP route: GET /defi/yields.
- `fx_reference_rates`: European Central Bank reference foreign-exchange rates for a chosen base currency, with the ECB observation date. Refreshed automatically by a Worker cron from Frankfurter. These are daily reference rates, not live tradable quotes, and every response carries `snapshot.captured_at` and `snapshot.age_hours`. Costs $0.005 USDC per call via x402 on Base; an unpaid call returns the payment challenge instead of data, and a call that returns no data is never settled so it costs nothing. Equivalent HTTP route: GET /fx.
- `manifold_markets`: Search or browse Manifold Markets questions, returning each one's probability, outcome type, volume, liquidity, unique bettor count, close time, creator and resolution state. Manifold is a PLAY-money venue denominated in MANA, so treat a probability as a crowd forecast rather than a real-money price; every response says so and reports the token. Costs $0.005 USDC per call via x402 on Base; an unpaid call returns the payment challenge instead of data, and a call that returns no data is never settled so it costs nothing. Equivalent HTTP route: GET /manifold/markets.
- `polymarket_events`: List Polymarket events — the grouped questions such as an election or a rate decision — ordered by volume, each with title, slug, end date, volume, 24h volume, liquidity, open interest, its full market count and the priced member markets themselves. Use it when a question has many candidate outcomes and you want them together rather than one at a time. Costs $0.005 USDC per call via x402 on Base; an unpaid call returns the payment challenge instead of data, and a call that returns no data is never settled so it costs nothing. Equivalent HTTP route: GET /polymarket/events.
- `polymarket_leaderboard`: Polymarket's public trader leaderboard by traded volume or realised profit over a 1d, 7d, 30d or all-time window, returning each trader's rank, published pseudonym and display name, wallet address and USDC amount. Use it to find who is moving size on the venue. A trader who publishes no name stays null; no name is inferred. Costs $0.005 USDC per call via x402 on Base; an unpaid call returns the payment challenge instead of data, and a call that returns no data is never settled so it costs nothing. Equivalent HTTP route: GET /polymarket/leaderboard.
- `polymarket_market`: One Polymarket market by Gamma id, slug or condition id, with its full outcome pricing and the LIVE CLOB order book for each outcome token: best bid, best ask, midpoint, spread and the top price levels with sizes. Use it before taking a position, to see real depth rather than only a last price. An outcome with no order book returns a null book rather than a fabricated price; an unknown identifier returns not_found and is not billed. Costs $0.008 USDC per call via x402 on Base; an unpaid call returns the payment challenge instead of data, and a call that returns no data is never settled so it costs nothing. Equivalent HTTP route: GET /polymarket/market.
- `polymarket_markets`: List live Polymarket markets ordered by volume or liquidity, each with its question, Gamma id, condition id, every outcome with its USDC price and CLOB token id, best bid/ask, last trade price, volume, liquidity and end date. Use it to see what the largest real-money prediction markets are pricing right now. Prices are probabilities between 0 and 1. Costs $0.005 USDC per call via x402 on Base; an unpaid call returns the payment challenge instead of data, and a call that returns no data is never settled so it costs nothing. Equivalent HTTP route: GET /polymarket/markets.
- `polymarket_trades`: Recent public trade prints for one Polymarket market, addressed by its condition id: timestamp, side, outcome, price, size, notional in USD, the trader's published pseudonym and wallet, and the transaction hash. Use it to see whether a quoted price is actually trading and who is behind the flow. Costs $0.005 USDC per call via x402 on Base; an unpaid call returns the payment challenge instead of data, and a call that returns no data is never settled so it costs nothing. Equivalent HTTP route: GET /polymarket/trades.
- `prediction_market_search`: Find a prediction market by question text across two venues at once — Polymarket (USDC, real money) and Manifold (MANA, play money) — returning a single normalised list with the venue, its currency, the question, the YES probability, volume, end date and a direct URL, plus a per-venue status so a venue that failed is visible rather than silently dropped. Use it when you know the question but not the venue or the id. Kalshi is deliberately not included: its API answers Cloudflare Workers with HTTP 429 on every attempt. Costs $0.008 USDC per call via x402 on Base; an unpaid call returns the payment challenge instead of data, and a call that returns no data is never settled so it costs nothing. Equivalent HTTP route: GET /prediction-markets/search.
- `stablecoin_peg_deviation`: USDC, USDT and DAI spot price against USD plus each one's peg deviation in basis points. Use this to check whether a stablecoin is holding its dollar peg before settling or holding value in it. Costs $0.005 USDC per call via x402 on Base; an unpaid call returns the payment challenge instead of data, and a call that returns no data is never settled so it costs nothing. Equivalent HTTP route: GET /stablecoin.
- `us_macro_indicators`: US macroeconomic indicators from the St. Louis Fed (FRED): effective federal funds rate in percent, CPI and core PCE index levels, unemployment rate in percent, and M2 money stock, each with its own observation date. IMPORTANT: this is a STORED SNAPSHOT, not a live read of FRED at request time — fred.stlouisfed.org blocks Cloudflare Workers (HTTP 520), so the snapshot is refreshed out of band. Every response carries `snapshot.captured_at` and `snapshot.age_hours`; check them before relying on the figures, and read `as_of` for the underlying observation date. CPI/PCE/M2 are index levels, not year-over-year rates. Costs $0.01 USDC per call via x402 on Base; an unpaid call returns the payment challenge instead of data, and a call that returns no data is never settled so it costs nothing. Equivalent HTTP route: GET /macro.
- `us_treasury_yields`: US Treasury constant-maturity yields for the 2, 10 and 30 year tenors in percent, the computed 10s2s curve spread with an explicit inverted flag, and the 30-year fixed mortgage rate. IMPORTANT: this is a STORED SNAPSHOT, not a live read — the FRED host blocks Cloudflare Workers (HTTP 520), so it is refreshed out of band. Every response carries `snapshot.captured_at` and `snapshot.age_hours`; check them before trading or quoting off these numbers. Costs $0.01 USDC per call via x402 on Base; an unpaid call returns the payment challenge instead of data, and a call that returns no data is never settled so it costs nothing. Equivalent HTTP route: GET /rates.
