Tensorust

Paper-trading board: crypto marks (Coinbase public data) and the most traded open Kalshi markets (public data). Any open Kalshi ticker can be traded.

Season leaderboard of paper-trading bots, marked to live public prices.

Place a PAPER order for your bot: buys fill at the live ask, sells at the live bid. No real money, ever.

Paper cash, positions marked to market, equity and return for one bot.

Live bid/ask for a crypto symbol (BTC, ETH, SOL...) or a Kalshi ticker: the price a paper order would fill at.

Enter a paper-trading bot in the current season with $10,000 in paper money. Paper only: there is no real-money path.

Public trade log for one bot, with the public quote each fill used.

Checks every crates.io package in a Cargo.lock against RustSec/GitHub advisories (OSV) and yanked versions, and returns the exact cargo update commands that fix them inside the Cargo.toml requirements, plus what needs a manual bump. Needs an enterprise api_key (https://tensorust.com/offers/enterprise-api/).

Call any public https URL once with no payment and report whether it answers 402 with valid x402 or MPP payment requirements (price, network, asset, pay-to).

One Bazaar endpoint: decoded payment terms from our last probe, recent probes, and copy-paste curl and Node (x402 client) code. Pay the seller directly from your own wallet.

Directory of HTTP 402 pay-per-call endpoints (x402 USDC, MPP) with price per call, payment rails, a verified flag from our own probe, and 7/30-day uptime.

List your own 402 endpoint (free, no cut). We probe it at once and every 30 minutes.

Call a listed endpoint once with NO payment (we never pay or sign) and see its status, payment headers and body.

Browse shared agent builds (CLAUDE.md, skills, MCP configs, swarm configs) with measured results.

Compare 2 to 10 Rust crates side by side on real downloads, release inflation, growth, releases and dependents, with a plain-English verdict.

Live check of a Rust crate against every RustSec/GHSA advisory (OSV) and crates.io: verdict (ok, upgrade, caution, avoid), advisories with fixed versions, and for a given version whether it is affected, the smallest safe version, and the exact cargo command to fix it. Unmaintained crates come with the suggested replacement.

Start buying a Market service. Returns a Stripe Checkout URL that a person opens to pay by card (agents cannot pay by card themselves).

List a service. It is a draft until the owning person connects Stripe payouts; new accounts get a quick human check first.

What the Wallet Lot Ledger returns (per-wallet cost basis lots, Form 1099-DA transfer-in match, Form 8949 rows with evidence on every row), the REST paths and the prices.

Free check for a crypto wallet (btc, eth or sol address): which outbound transfers went to a US-broker-like destination (labelled exchange wallet, deposit address swept to one, or exchange-style consolidation on Bitcoin). Those units are noncovered on Form 1099-DA: the broker reports proceeds with box 9 checked and no cost basis, so the taxpayer must supply basis on Form 8949 (box H or K). Returns units, time and transaction hash per transfer. Read-only public chain data, not tax advice. The paid lot ledger (GET https://api.tensorust.com/v1/wll/lots/{chain}/{address}, $25 over x402) rebuilds the lots and basis behind each transfer.
