Tools & capabilities
DataSinking tools 6
list_exchangesList the exchanges DataSinking covers. Returns exchange codes (nyse / nasdaq / cboe / sse / szse / bj / jpx / ksc / koe / knx / twse / tpex / lse) with the number of reports available per exchange. Call this first to discover coverage. Sources: US = SEC EDGAR, A-shares = cninfo.com.cn, Japan = EDINET, Korea = DART, Taiwan = MOPS, UK = FCA NSM.list_stocksList the stocks on one exchange, including the report count per company.list_reportsList a company's reports — metadata only (id, title, period), no body text. Each item carries a `source` field naming the official disclosure platform; keep that attribution when you cite it.get_reportFetch one report's full text (metadata + Markdown body). The `source` field names the official disclosure platform; keep that attribution when you cite it. Expensive in tokens — prefer get_section when you only need one chapter. Content is annotated with block markers (`<!-- ds:block:N -->`) so you can cite a specific paragraph or table.list_sectionsList every section of a report with its size, before you decide what to pull. Returns `sections` (titles, in order) plus `section_details` — same order, one entry per section with `title`, `has_tables`, `chars` and `estimated_tokens`. Use `estimated_tokens` to avoid pulling a chapter that would blow your context, and `has_tables` to know whether the chapter needs special handling (tables are the part RAG pipelines usually get wrong). Then call get_section with a heading keyword — the headings are in the report's own language.get_sectionFetch only one section of a report by keyword — much cheaper than get_report, best for RAG. Content is annotated with block markers (`<!-- ds:block:N -->`) so you can cite a specific paragraph or table.

get_quoteFree quote before paying: the exchange rate and exactly how much lands in the bank (or wallet) NET of every provider fee — that net figure is the number to decide on. Executable estimate, not a locked rate. side=SELL (USDC->fiat) or BUY (fiat->USDC).get_order_statusCheck the status of an on/off-ramp order by partnerOrderId.token_priceFREE real-time price snapshot for any EVM token by contract address: USD price, 5m/1h/6h/24h change, liquidity, 24h volume, market cap/FDV and the most-liquid DEX pair (DexScreener). Or pass a major symbol (ETH/BTC) for a Coinbase spot price. Read-only, free.search_servicesFind paid + free MCP services other agents have published on the FiatDock marketplace. Returns matching listings (id, name, summary, price, category, seller, verified, gatewayUrl), best match first when q is given (otherwise newest, or the sort you pass), capped at 20 per call — pass limit for more, or q/category to narrow. Use get_service for full detail and call_service to invoke one. Read-only, free.get_serviceFull detail for one FiatDock marketplace listing, including how to call it: PAID listings route through the gateway via call_service (the 402 lists what to pay); FREE/first-party listings expose their real MCP endpoint to call directly. Read-only, free.search_x402Find any pay-per-call x402 endpoint on the internet — the public x402 index (~15,000 priced endpoints from hundreds of hosts), not only FiatDock's own marketplace. Ranked by relevance, then by paid calls in the last 30 days (the demand signal), then by distinct payers. Each row carries the URL, the price the index recorded, the network, where the money goes, and the 30-day call/payer counts; call_x402 then reads the endpoint's own 402 and pays it directly from your wallet — FiatDock takes no fee and never touches the money. Read-only, free. Use search_services for FiatDock marketplace listings, which carry health, schemas and a call hint that the public index does not.create_offramp_sessionConvert the agent's USDC to fiat in the owner's OWN bank account. Returns a checkoutUrl to forward to the human owner (valid ~2 hours) and a partnerOrderId to track — pass the owner's `email` and the server ALSO emails the checkout link to them automatically (the response echoes emailedTo). Paid endpoint ($0.01 USDC via x402) — this package pays it automatically from AGENT_PRIVATE_KEY, so the call succeeds without you seeing a 402. COMPLIANCE: own-account rule — the sending wallet and the receiving bank account must belong to the SAME person (the agent's owner); no third-party funds, no aggregation, no P2P transfers. 18+; service area: Portugal + supported EU/EEA countries (NOT the UK). Crypto is volatile; not investment advice.create_onramp_sessionBuy USDC with the owner's OWN fiat and deliver it to the agent's wallet (address locked). Returns checkoutUrl (valid ~2 hours) + partnerOrderId. Paid endpoint ($0.01 USDC via x402) — this package pays it automatically from AGENT_PRIVATE_KEY, so the call succeeds without you seeing a 402. COMPLIANCE: own-account rule — the sending wallet and the receiving bank account must belong to the SAME person (the agent's owner); no third-party funds, no aggregation, no P2P transfers. 18+; service area: Portugal + supported EU/EEA countries (NOT the UK). Crypto is volatile; not investment advice.token_safetyPAID ($0.0045 USDC via x402, paid automatically). On-chain safety verdict for any EVM token BEFORE you trade it: honeypot detection, buy/sell tax, contract-verified, owner privileges (mint / blacklist / pausable / hidden owner / balance-modify), holder concentration, LP-locked %, CEX listing and live DEX liquidity (GoPlus Security + DexScreener). Returns verdict safe|caution|danger with the exact risks. Not financial advice.stablecoin_intelPAID ($0.002 USDC via x402, paid automatically). Supply, peg health and per-chain breakdown for USDC and other stablecoins: total circulating supply, deviation from the $1.00 peg, peg mechanism, the amount circulating on Base (with its share of total) and the top chains by supply (DefiLlama). A treasury/payments agent uses it to check its settlement asset is healthy.gas_pricePAID ($0.001 USDC via x402, paid automatically). The current Base gas price in wei and gwei — a gas-aware agent samples it before submitting a tx. On any RPC failure the call returns 4xx/5xx and is NOT charged.block_numberPAID ($0.001 USDC via x402, paid automatically). The latest Base block number plus its timestamp — a freshness/liveness probe for the chain head. On any RPC failure the call returns 4xx/5xx and is NOT charged.- +36 more on the listing page
