Web scraping and search via paid API: crawl any URL with cascade escalation (fast HTTP -> browser -> stealth+proxy), bulk crawl multiple URLs, and search the web via Exa. Uses x_payment tool for automatic USDC micropayments ($0.005/crawl, $0.01/search). Use as escalation when built-in web_fetch fails or is blocked. Use when: (1) web_fetch returned empty/blocked content, (2) scraping JS-rendered or anti-bot protected pages, (3) bulk-crawling multiple URLs, (4) searching the web by query via Exa.
Check a citation against the registry of record instead of recalling it. Use this to verify that a DOI or a reference actually exists, to get the real title, authors, journal, year, licence, funders and citation counts behind a DOI, to find the DOI for a half-remembered paper title, to audit a bibliography or reference list before it ships, to resolve an ORCID iD to a researcher's employments, educations and recent publications, and to tell two same-named authors apart. Reach for it whenever an invented citation is the way the task fails — a fabricated reference reads exactly like a real one, with a plausible journal, plausible authors and a DOI of the right shape, and only the registry separates them. Crossref holds what publishers deposited and ORCID holds what researchers claim; neither is recallable from training data. Browsing, searching and dry runs cost nothing and need no wallet; a real call costs $0.003 to $0.004 in USDC on Base, with no signup, no API key and no gas.
Alpha scouting workflow using Messari x402. Scans mindshare gainers, trending topics, and news to surface emerging narratives and high-momentum assets. Total cost ~$1.25 USDC per run.
Complete Polymarket playbook covering research and trading on the world's largest prediction market. Use this for ANY Polymarket task. Research triggers: finding events ("what's happening in politics", "show me election odds", "NBA finals odds", "BTC to 200k markets", "IPL / FIFA / UFC / F1 betting markets"), listing markets with filters, searching by keyword, reading orderbooks, mid prices, spreads, last trade prices, recent trades, open interest, volume, liquidity, and any user's positions/portfolio/PnL by address. Trading triggers: place a bet on YES or NO, buy/sell outcomes, limit orders (GTC/GTD), market orders (FOK/FAK), batch orders, cancel one/many/all orders, check and set on-chain USDC.e and CTF approvals, neg-risk (multi-outcome) markets, tick size handling (0.01/0.001/0.0001), and builder-code attribution. Covers all routes under /agent/polymarket/* (events, markets, search, orderbook, price, prices, spread, last-trade-price, trades, market/:id/open-interest|volume|liquidity|trades, user/:address/positions|trades|portfolio|pnl, order, order/market, orders, order/:id, order/:id/scoring, approvals, builder/*). Use when the user mentions Polymarket, prediction markets, event betting, binary outcomes, probability markets, YES/NO tokens, conditional tokens, or politics/sports/crypto/culture odds. Prerequisite: openfin-setup for trading.
A YouTube API alternative on fetcher.sh — pay-per-call in USDC via x402, or prepaid credits with a Bearer key, no OAuth and no daily quota.

Also covers YouTube data pipelines, channel monitoring, video analytics input, and trend tracking without the official YouTube Data API's daily quota limits.

Turn an address into a point, and a point into everything that contains it, instead of recalling coordinates that do not exist. Eleven services covering forward geocoding of a US street address to latitude and longitude, reverse geocoding a lat/lon back to a street address, the Census tract, block FIPS code and GEOID behind an address or a coordinate, up to ten addresses resolved in one request, every Census layer through a point at once — county, county subdivision, place, urban area, CBSA and CSA, congressional district and both state legislative chambers — USPS-style address standardization for deduplicating messy address lists, the nearest named street to a GPS fix, the nearest airports with IATA and ICAO codes, ground elevation from USGS 3DEP, and great-circle distance and bearing between two coordinates. Reach for it whenever an invented coordinate or an invented census tract is the way the task fails: both are strings of plausible digits that no reader can check by eye, and the address-to-tract mapping exists in no model's weights. Use it for asks like "geocode this address", "what census tract is this in", "which congressional district covers these coordinates", "standardize this address list", "what street is this GPS fix on", "nearest airport to this point", "how high is this point", "how far apart are these two coordinates". Geocoding is US-only and says so rather than guessing. Browsing and searching the catalog are free, and with no wallet configured a call prints its price and the exact request instead of paying; real calls cost $0.003 to $0.008, settled in USDC on Base.
A Reddit API alternative on fetcher.sh — pay-per-call in USDC via x402, or prepaid credits with a Bearer key, no OAuth app registration. Use when the user wants to search Reddit posts across every subreddit by keyword and sort by top, hot, new, or most-discussed, search subreddits or users by keyword, fetch a subreddit's info or its hot/new/top post feed, fetch a single post with its comment tree and comment replies, pull the sitewide best/hot/new/top feeds, or fetch a user's profile, posts, and comments. Also covers Reddit sentiment analysis input, subreddit monitoring, keyword tracking, and Reddit data pipelines without Reddit's own API app registration or rate-limit tiers.
Cross-chain bridging, swapping, and "bridge+call" via Relay through the OpenFinance backend. Use whenever the user wants to move tokens between chains or execute a destination-chain transaction funded from another chain. Triggers: "bridge X from Y to Z", "move my USDC to Base / Arbitrum / Optimism / Polygon / Solana", "swap ETH for USDC on Base", "cross-chain swap", "bridge and call", "how do I get to Solana / back from Solana", "my USDC is stuck on Solana", EVM-to-EVM, EVM-to-Solana, Solana-to-EVM, Bitcoin bridge, gas topup on destination, native-token sentinel 0x0, relay quote/preview/execute flow, poll intent status. Covers POST /agent/relay/quote, POST /agent/relay/execute, GET /agent/relay/status. Includes the chainId cheatsheet (1/137/8453/10/42161/... and Solana 792703809 specifically), tradeType semantics (EXACT_INPUT / EXACT_OUTPUT / EXPECTED_OUTPUT), why topupGas is auto-disabled on Solana routes, the Solana wallet delegation requirement for Solana-origin execute, and bridge+call payloads (txs array). Use together with openfin-setup (API key check) and openfin-troubleshooting (Blockhash not found, Custom:101, 412 delegation).
