Market statistics

The same 1-minute/daily aggregates the analyze pages chart: OHLC, VWAP, trades, turnover, spreads, top-of-book depth.

• get_market_snapshot — Live snapshot: last price, 24h change, 60-min turnover/trades, spread (bps), top-1/top-20 depth.

Your account (sign-in required)

Connect with OAuth sign-in and the agent can work with your CryptoStruct account directly.

• list_my_orders — Your order history: status, totals, credits applied, invoice PDFs, tokenized order links.
• get_my_files — Every file you own as a flat list with delivery state and direct download URLs (owner links never expire).
• get_my_subscription — Premium status, credit balance, the latest credit-ledger entries and your agent-spending settings (mode, caps, spent today).
• preview_checkout — Dry run of a purchase: already-owned files, unavailable days, credit cover — and whether create_checkout will complete from credits, ask for your approval, or hand over a Stripe URL.

Buying data

The agent assembles the purchase; you stay in control of the money. Card payments happen in the browser via Stripe. Credits (signed-in) are spent only with your consent: by default every agent order lands on an approval page you confirm; opt into autonomous mode in your account to let fully credit-covered orders complete within your per-order and daily limits. Everything is 1 EUR per instrument-day — the raw tick file or the derived 1-minute stats CSV (kind: minute_csv), incl. archived days beyond the ~30-day minute retention.

• create_checkout — Start a purchase (max 100 items per checkout; tick files and/or minute_csv items). Card: returns a Stripe checkout URL to open in the browser. Credits: returns approval_required with an approval_url for you to confirm — or, in autonomous mode and within your caps, the order completes immediately. Optional max_credit_cents lets the agent cap its own spend.
• get_checkout_status — Poll the checkout by session_id (card) or order_id (signed-in; credit/approval orders); once paid it returns the order id and download token.
• get_order_files — List a paid order's files with delivery state and direct download URLs.
• request_file_restore — Wake an archived (cold-storage) file — restores take up to ~12 hours.

The /mcp/auth endpoint asks for sign-in on connect (OAuth in the browser). Same tools as /mcp.

Fair use & rate limits

Anonymous access shares a per-IP budget (weighted per tool call); signed-in callers get their own per-account budget, and Premium raises it 5x. On a RATE_LIMITED error, back off for the indicated seconds. Need sustained programmatic scale beyond that — batch queries, bulk exports? Talk to us: the pricing page lists the ways in.

Units & conventions

Market values (turnover, depth) are USD; sale prices are EUR. All file sizes are compressed (zstd) bytes. Minute-level statistics are retained for roughly 30 days; daily aggregates reach back further. Instrument ids are stable for the lifetime of an instrument and identical across MCP, shop and analyze pages.

Guest vs signed-in orders

Anonymous MCP purchases use the guest flow: the download link and token from get_checkout_status stay valid for 30 days. Signed-in (OAuth) purchases are linked to your account permanently and drop already-owned files automatically.

Credits & agent consent

Your credits are never spent by an agent without your consent. Default — approve each purchase: create_checkout returns approval_required plus an approval page where you pay with credits (or by card) or discard the order; unapproved orders expire after 24 hours with nothing charged. Opt-in — autonomous within limits (https://cryptostruct.com/account/agents): a fully credit-covered order completes immediately as long as it fits your per-order cap and your rolling 24-hour cap; anything larger, or not fully covered, comes back to you for approval instead of failing. The agent can pass its own max_credit_cents on top. Only you can change these settings — from the website, never through an agent's token — and every autonomous purchase is listed on the Agents tab and in your credit ledger.
