• POST/block-receipts—No price listedEvery transaction receipt in one block, fetched as a single upstream read and summarised: tx count, succeeded vs failed, total gas used, total fees, log count, contract creations, tx-type mix - plus compact per-transaction rows (hash, from, to, status, gas used, effective gas price, fee, log count) capped at 300. Block analytics, failed-tx hunting, or 'who paid what in block N' without N separate receipt calls. On mppscan and x402 Bazaar
• POST/skill/yield-dashboard—No price listedCurrent yield curve snapshot: full Treasury curve, key spreads, and average rates in one call. Yield dashboard skill pack: one x402 payment runs 3 underlying tools (treasury-yield-curve, yield-curve-spread, treasury-avg-rates); partial-success per step. On mppscan and x402 Bazaar
• POST/skill/regulatory-watch—No price listedThe 'who just filed / who just bought / what just IPO'd / what does the full-text search say' monitoring loop. Five EDGAR tools composed: full-text search for a keyword, surface recent filings on the matched companies, pull insider Form 4 transactions, pull 13F institutional holdings changes, and check the IPO calendar. Different from sec-filings-deep-dive (which goes deep on one company's earnings) - this is the wide-and-recent radar. On mppscan and x402 Bazaar
• GET/edgar-recent-ipos—No price listedRecently-filed S-1 (initial registration) or 424B4 (final prospectus - actual priced IPO) filings across all US issuers. Default returns S-1 filings (companies preparing to IPO) in the last 30 days; pass form=424B4 for actual IPOs that priced. Source: EDGAR full-text search. On mppscan and x402 Bazaar
• POST/json-validate—No price listedValidate a JSON document against a JSON Schema (draft-07 subset) and get the list of violations. Supports type, required, properties, items, enum, const, min/max, length, pattern, format, anyOf/allOf/oneOf/not, additionalProperties. Deterministic - check an agent's structured output before you trust it. On mppscan and x402 Bazaar
• POST/decide—No price listedDescribe a job and get a call-ready plan: which tools, across this catalog and outside x402 sellers with a recently verified 402, solve it end to end, in what order, with fallbacks, input params that validate against each tool's schema, and cost/latency estimates. Priced by depth: quick (one best tool), plan (steps + fallbacks), full (plan + params + compiled prompt). The fee comes back as a credit toward running the plan with POST /api/decide/execute. On x402 Bazaar
• POST/skill/pdf-pipeline—No price listedFull PDF processing pipeline - metadata, markdown conversion, and first-page extraction in one call. PDF processing pipeline skill pack: one x402 payment runs 3 underlying tools (pdf-info, pdf-to-markdown, pdf-extract-pages); partial-success per step. On mppscan and x402 Bazaar
• POST/memory/grant—No price listedShare your namespace with another wallet so different agents can coordinate through it. Grant read or readwrite access to a grantee wallet, optionally with a TTL. This is the cross-agent sharing a single agent cannot provide for itself. On mppscan and x402 Bazaar
• POST/skill/schema-guard—No price listedContract-test a JSON payload in one call: validate it against your schema, infer the schema the payload actually implies, diff the two to expose drift, and return a normalized pretty-print. Schema guard skill pack: one x402 payment runs 4 underlying tools (json-validate, json-schema-infer, json-diff, json-format); partial-success per step. On mppscan and x402 Bazaar
• POST/attest—No price listedWrite an on-chain attestation (Ethereum Attestation Service on Base) that binds a call you paid for to the bytes you received: the tool slug, sha256 of the JSON response, the settlement chain and transaction, the payer, the time served and the price, signed by this server's wallet. Give it the settlement transaction from the PAYMENT-RESPONSE (or Payment-Receipt) header of any settled call; the attestation UID and its public page on base.easscan.org come back. On mppscan and x402 Bazaar
• POST/uuid-v5—No price listed On mppscan
• POST/options-ticker—No price listedOne options instrument live: mark, last, bid and ask with sizes, index price, open interest, mark, bid and ask implied volatility and the full greeks (delta, gamma, vega, theta, rho). Use it when an agent holds or is quoting a specific contract and needs its current risk numbers. On mppscan and x402 Bazaar
• GET/treasury-avg-rates—No price listedLatest average interest rates the US Treasury is paying by security type (Bills, Notes, Bonds, TIPS, FRNs, marketable vs non-marketable). Public domain, no key. No params - returns the most recent reporting month. On mppscan and x402 Bazaar
• POST/skill/text-hygiene—No price listedTurn a wall of dirty text - chat logs, scraped pages, user-generated content, log dumps - into something safe to store, search, and pipe into the next step. Measure first, redact PII before anything else touches the data, then dedupe, sort, extract entities, surface keywords, and grade the readability of what's left. Text hygiene skill pack: one x402 payment runs 7 underlying tools (text-stats, redact, dedupe-lines, sort-lines, extract-entities, keywords, readability); partial-success per step. On mppscan and x402 Bazaar
• POST/break-even—No price listedBreak-even point for a product: the units and revenue at which total revenue covers fixed plus variable costs. Also returns contribution margin and margin ratio. On mppscan and x402 Bazaar
• POST/seller-payability—No price listedBuy one call from an x402 seller endpoint right now and report exactly what happened: the unpaid call's status, the 402 decoded (accepts, chains, payTo, asset, price), whether the accept's EIP-712 domain name matches the token it names (the defect that silently makes a whole catalog unpayable), whether a stock client's signed payment was accepted, the settlement receipt and transaction, a slice of the response body, and the time each leg took. Ends in plain-English flags, never a score. On mppscan and x402 Bazaar
• POST/effective-annual-rate—No price listedConvert a nominal annual rate (APR) compounded m times per year into the effective annual rate (EAR / APY): (1 + apr/m)^m - 1. Set continuous:true for e^apr - 1. On mppscan and x402 Bazaar
• GET/rwa-markets—No price listedMarket data for tokenized real-world assets - tokenized stocks (Nvidia, Tesla, pre-IPO names), ETFs and commodities like gold - ranked by market cap or volume: price, market cap, 24h volume, 24h high/low and change, in your currency. Filter by type or a list of ids. Note these are the ONCHAIN wrappers' figures (what is tokenized and trading), not the underlying's exchange listing. Cached in-process for 60 seconds. Data provided by CoinGecko. On mppscan and x402 Bazaar
• POST/http-check—No price listedCheck any public URL: status code, latency, final URL after redirects, and response headers. The uptime primitive for agent monitors. On mppscan and x402 Bazaar
• POST/skill/gas-optimizer—No price listedFind the cheapest gas right now: Base gas, Ethereum gas, Base fee estimate, and ETH price for USD conversion.

• POST/forecast-naive—No price listedThree textbook baseline forecasts: mean (forecast = average of history), naive (forecast = last value), drift (linear extrapolation from first to last point). Use as a sanity floor - any sophisticated method (SES, Holt, Holt-Winters) should beat the best of these on a backtest, otherwise the extra complexity isn't earning its keep. Returns point forecasts + 95% prediction intervals per Hyndman §3.1. On mppscan and x402 Bazaar
• POST/options-summary—No price listedA one-call options market summary for a currency: index price, DVOL, call and put open interest with the put/call ratio, total open interest, 24h volume, a per-expiry breakdown, the most active instruments and the perp's mark, funding and open interest. Use it when an agent needs the state of BTC or ETH options before drilling into a chain. On mppscan and x402 Bazaar
• POST/json-pointer—No price listedResolve an RFC 6901 JSON Pointer (e.g. /items/0/name) against a JSON value. Returns the value or found:false. On mppscan and x402 Bazaar
