Updates

What's shipped, in order. See the API reference for full endpoint details.

v1.6Oct 29, 2026
  • Token risk now shows what the contract itself says — whether ownership is renounced, whether it's an upgradeable proxy, whether it has mint, pause or blacklist functions — and which published token lists include it. If a different address is listed under the same symbol on a curated list, it flags that lookalike. These are neutral facts, not a verdict.
  • New endpoint: GET /api/tokens/risk — token risk for up to 10 tokens in one call ($0.05). The MCP server and the AgentKit package have a matching tool.
v1.5Oct 28, 2026
  • New endpoint: GET /api/token/{address}/pre-trade-gate ($0.05) — token risk, top traders and an optional wallet check combined into one clear / caution / avoid verdict, cheaper than calling the three separately.
  • New: ulvane-agentkit, a Coinbase AgentKit action provider, alongside the MCP server (now with a pre_trade_gate tool). Both check a spend cap against what the server actually asks for, and verify each response's signature.
  • Free GET /api/pricing: a machine-readable price list so an agent can budget before it calls.
  • Wallet PnL, wallet risk, top traders and the pre-trade gate now read from The Graph across Aerodrome, Uniswap v3 and Uniswap v4 on Base, looking at up to 200 recent swaps instead of 50. Token risk reads names straight from the chain, so it works for any token. Every response states exactly which DEXes it covered.
  • New public pages: /status (live health of the data sources) and /verified-tokens (the hand-vetted token list).
v1.4Sep 25, 2026
  • New: an MCP server, so Claude, Cursor and any MCP client can call Ulvane's endpoints as tools. The agent's own wallet pays per call over x402 — the key stays local, with a built-in per-call spend cap. Setup is in the docs.
v1.3Sep 22, 2026
  • New: a public Leaderboard — top realized-PnL wallets on Aerodrome (Base's largest DEX) across 1h/8h/12h/1d windows, free, no wallet needed. Sourced from The Graph rather than Bitquery, so a chain-wide scan is actually feasible.
  • The wallet PnL demo now shows a realized-PnL chart over time, not just two numbers.
v1.2Sep 21, 2026
  • New endpoint: GET /api/wallet/{wallet}/risk — the wallet-level counterpart to the token risk check, flagging a wallet if it's recently traded a known impersonator token.
  • Docs page now has a live try-it demo and TypeScript/Python quickstarts for making a paid request.
v1.1Sep 20, 2026
  • Every paid response is now signed (EIP-191) — proof of what we said and when, verifiable offline without asking Ulvane again. Try it on the docs page.
  • Added a machine-readable OpenAPI spec (/openapi.json) for agent frameworks that ingest OpenAPI directly.
  • Expanded the verified-token allowlist (MORPHO, VIRTUAL, VVV, AERO, cbBTC, cbXRP added).
v1.0Sep 18, 2026
  • Launched: three x402-priced endpoints live on Base mainnet — wallet PnL, token risk/impersonator check, and whale/top-trader tracking.
  • Added a free, rate-limited demo on the homepage so anyone can try it without a funded wallet.
  • Published the full API reference and FAQ.
