Changelog - May 25-31, 2026

​

2026-05-27 - More reliable sports discovery

• GET /v2/sports/leagues/{code}/games resolves each public league code to its sports series, then applies status, sort, direction, limit, and offset consistently.
• Responses include series_id, source, fallback, and stale, so clients can tell which source produced the result and whether a recent last-known-good response was used.
• Known event variants such as exact-score, halftime-result, and more-markets pages are deduplicated in favor of the canonical game.
• GET /v2/sports/search can fall back to alternate Polymarket event discovery instead of returning an upstream 502 immediately.
• GET /v2/sports/games/{slug}/history now defaults to the full available history when no interval or timestamp range is supplied.
• GET /v2/sports/live can supplement a partial sports summary with league-level event data instead of returning mostly empty arrays.

​

2026-05-27 - One-month USDC checkout

• Starter, Growth, and Enterprise pricing cards offer a Pay 1 month with USDC option alongside normal card subscriptions.
• USDC purchases are one-time 30-day access grants, not recurring subscriptions.
• A later USDC purchase extends access from the end of the customer’s current USDC period rather than shortening or replacing it.
• Customers with an active card subscription are protected from accidental double payment. Trialing or past-due card users can switch to one-month USDC access.
• Existing card checkout, account login, API keys, and plan entitlements continue to work as before.

​

2026-05-27 - V3 wallet P&L alignment, fees, rebates, rewards, and PolyUSD flows

• Default/all-time GET /v3/wallets/{address}/pnl/events now returns a single all-time bucket so it agrees with GET /v3/wallets/{address}/pnl.
• Explicit time-windowed P&L events (period, after, or before) return realized P&L buckets and ignore timestamp-0 artifacts.
• Added GET /v3/wallets/{address}/fees-paid for fee-bearing wallet fills.
• Added GET /v3/wallets/{address}/polyusd-flows for wallet PolyUSD deposits and withdrawals.
• Added GET /v3/wallets/{address}/rebates for maker rebates.
• Added public reward-market configuration at GET /v3/rewards/markets and GET /v3/rewards/markets/{condition_id}.

• Fees paid and maker rebates are intentionally separate surfaces. LP reward market configuration is public; per-wallet earned LP rewards require authenticated Polymarket data and are not exposed as an arbitrary-wallet lookup in the public docs.
• GET /v3/wallets/{address}/activity remains the conditional-token activity feed; PolyUSD deposits and withdrawals now live in the separate wallet PolyUSD flows endpoint.

​

2026-05-26 - Webhooks beta: first observed position opens

• position_status_change now detects first observed none to open transitions for watched wallets.
• Existing positions are established as the wallet’s baseline when it is first watched, so future transitions are emitted without replaying historical opens.
• Adding another watched wallet does not replay source activity from before that wallet’s own baseline.
• Payloads include previous_amount, new_amount, delta_amount, transfer_amount, source, source_event_id, block and transaction fields, and market enrichment.
• Filters include wallet_addresses, token_ids, condition_ids, event_slugs, tags, status_from, and status_to.

​

2026-05-26 - Polymarket Profiles API

• GET /v3/polymarket/profiles/username-available checks a requested username. Local format is 3-32 letters, numbers, or underscores; Polymarket remains the final authority.
• POST /v3/polymarket/profiles/username/challenge returns the Polymarket sign-in message and polynode consent typed data for the user’s wallet. Challenges expire after 10 minutes.
• POST /v3/polymarket/profiles/username/complete verifies both signatures and completes the profile or username action.
• GET /v3/polymarket/profiles/{address} returns normalized public profile information.

​

2026-05-26 - TypeScript SDK v0.10.13: V3 parity, resolver, and profile helpers

• pn.v3 namespace for the V3 historical data API while preserving existing top-level SDK behavior.
• Typed V3 methods for wallet summaries, wallet P&L, P&L events, wallet trades, wallet positions, global trades, global positions, market search, market price, market trades, market positions, leaderboard, tags, builders, builder trades, fees, resolutions, conditions, and token info.
• Builder trade filters in the SDK: tokenId, conditionId, marketSlug, eventSlug, side, category, tagSlug, minAmount, after, before, limit, and offset.
• pn.resolve(query) for wallet, EOA, or username resolution, returning { safe, eoa, username, type }.
• Fully typed pn.walletOnchainPositions() responses, including market metadata, status, price, P&L, and lifecycle timestamps.
• V3 Polymarket profile helpers: polymarketUsernameAvailable, createPolymarketUsernameChallenge, completePolymarketUsername, and polymarketProfile.

npm install polynode-sdk@0.10.13

​

2026-05-25 - Rust SDK v0.13.5 deposit-wallet onboarding fix

• ensure_ready() recognizes an already-deployed deposit wallet from its onchain contract state instead of re-entering a failed deployment loop.
• Deposit-wallet approval batches contain only the supported V2 pUSD and Conditional Tokens approvals.
• Nested approval batches use the correct EIP-712 encoding and normalized wallet signature format.
• After setup, the SDK refreshes the V2 CLOB balance and allowance state for both new and already-deployed deposit wallets.
• Orders continue to use the deposit wallet as maker, the owner EOA as signer, and signature type 3 (POLY_1271).

polynode = { version = "0.13.5", features = ["trading"] }

2026-05-25 - Public plan-limit conventions clarified

• REST limits were 60 requests/minute on Free, 600 on Starter, 3,000 on Growth, and custom on Enterprise.
• Event WebSocket and Orderbook WebSocket connection limits were each 1 on Free, 10 on Starter, 50 on Growth, and unlimited on Enterprise.
• A subscription could contain up to 10,000 filter items; paid plans had unlimited session time and unlimited orderbook market subscriptions.
• API-key allowances were 1 on Free, 3 on Starter, 10 on Growth, and 25 on Enterprise.
• Expensive endpoints could still carry endpoint-specific caps or plan requirements in addition to the plan’s main REST allowance.
