Each needs a user API key with the matching permission turned on at [your settings](https://sentx.io/profile/settings?tab=api) (SentX API tab, API Permissions). Turning on Manage Collection Offers or Manage Allowance asks your wallet to approve the change. Send the key as the `apikey` query parameter: these endpoints do not read the x-api-key header.\n\n**Running a bot safely.** SentX only ever returns unsigned transaction bytes, and your wallet key never leaves your signer. The risk is the combination of a key and a bot: **a stolen API key plus a bot that refills its allowance automatically can reach your whole wallet balance.** Whoever holds a key with Manage Collection Offers can cancel your offers and place their own up to your current allowance; if your bot then approves every `requiredAllowance` it is asked for, each refill raises what they can spend. `requiredAllowance` covers every active collection offer on the wallet, including offers placed by someone else using your key, so checking `/v1/user/orders/list` does not tell you who placed them.\n\nBefore your signer signs bytes from `/v1/user/allowance/approve`, decode them and check:\n- the transaction is one AccountAllowanceApprove with no other operations;\n- the owner is your wallet;\n- the spender is on a spender list you keep yourself, not one read from the API response;\n- the amount is exactly what you asked for;\n- the max transaction fee is 10 HBAR or less.\n\nKeep your own policy in the signer, not in the bot: which collections and prices you accept, a maximum total exposure and a cumulative refill budget.

If the user\ndid not sign, or the transaction failed, do not call this endpoint — it will reject.\n\nBefore removing the listing the server checks two independent things:\n\n1. **Binding** — if you send a `transactionId`, it must equal the one returned by `unlistnft`\n   (its `transid` field, also embedded in `transBytes`). Any other id is rejected, even a\n   valid successful one. If you omit it, the server verifies the transaction it prepared\n   for you — so signing and submitting `transBytes` is still mandatory either way.\n2. **Receipt** — that transaction must have reached consensus with `SUCCESS` on the Hedera\n   network, be of the expected type, and have been paid for by the wallet in `user_address`.\n\nThis is what authorises the delist. There is no allowlist and no `userAuthToken` on this\nendpoint: because Hedera charges the payer, a transaction bearing that id cannot succeed\nunless the NFT's owner signed it, so a confirmed receipt IS the owner's authorisation.\n\nBoth transaction id formats are accepted — `0.0.123@1785062564.821914533` (SDK/wallet) and\n`0.0.123-1785062564-821914533` (mirror node / HashScan).\n\n**Timing.** Call this as soon as your submit returns. The server polls mirror node for up to\n~14 seconds waiting for the transaction to be indexed, so you do not need to sleep first. If\nit is still not visible you get `CODE=TXUNCONFIRMED` — wait a few seconds and call again with\nthe same `saleVerificationCode` and `transactionId`. Nothing has been changed at that point.\n\n**Single use.** A `saleVerificationCode` is consumed once the server reaches a verdict.\nRetrying after a rejection that is not `CODE=TXUNCONFIRMED` or `LISTING_BUYER_LOCKED` requires a fresh\n`unlistnft` call.\n\n**A buyer's checkout came first (`errorCode: \"LISTING_BUYER_LOCKED\"`, `retryable: true`).** The\nuser's transaction is confirmed on-chain, but a buyer started checking out on this NFT before it, so the\nlisting was not removed yet and nothing was changed. When `sellerClaim.active` is `true`, new checkouts\non the NFT are paused so the change can go through: call this endpoint again, unchanged (same\n`saleVerificationCode` and `transactionId`), after `retryAfterSeconds`, and keep calling before\n`sellerClaim.secondsLeft` runs out until it succeeds. The pause ends about 5 minutes after the last\nrefused call. The `saleVerificationCode` stays valid for up to 30 minutes after each such answer. Do not\nask the user to sign again. When the same answer carries `retryable: false` and\n`reprepareRequired: true`, this request could not be kept: calling again with the same\n`saleVerificationCode` cannot succeed, so call `unlistnft` again once the checkout ends.\n\n**EVM/ERC NFTs:** identical flow, same two checks, plus a third: the signed contract call must be\nexactly the one `unlistnft` prepared (the same contract, function and arguments, read on two mirror\nhosts). That is `setApprovalForAll(operator, false)` on the seller's last listing in the collection,\notherwise the read-only `balanceOf` call that keeps the seller's other listings buyable (see\n`unlistnft`). Any other call is refused with `TXWRONGTYPE`.

Use this to build an NFT detail page\nshowing the full lifecycle: when it was listed, any price adjustments, when it sold, etc.\n\n**Sale history for a specific NFT** — only completed purchases:\n```\nGET /v1/public/market/events?token=0.0.878200&serialId=877&eventType=sold\n```\nIncludes both direct marketplace sales (nftSaleTypeId 1) and accepted collection offers /\ninstant sells (nftSaleTypeId 35). Use `eventDateUnix` + `price` to render a price-over-time chart.\n\n**Price change history for a collection** — track when sellers adjust listing prices:\n```\nGET /v1/public/market/events?token=0.0.878200&eventType=price_changed\n```\nEach event includes `previousPrice` (the old price) and `price` (the new price), so you can\ncompute the direction and magnitude of each change. Useful for detecting price drops/increases.\n\n**New listings for a collection** — detect when NFTs are listed for sale:\n```\nGET /v1/public/market/events?token=0.0.878200&eventType=listed\n```\nReturns only new-listing events. Combine with `since` for a \"new listings since last check\" feed.\n\n**Delistings for a collection** — detect when NFTs are removed from sale:\n```\nGET /v1/public/market/events?token=0.0.878200&eventType=delisted\n```\nTrack when sellers cancel their listings. Not available in the activity feed (website only shows sales/listings).\n\n**Collection-wide activity feed** — all event types for one collection:\n```\nGET /v1/public/market/events?token=0.0.878200&limit=50\n```\nFull feed of everything happening in a collection: listings, price changes, sales, and delistings.\n\n**Global marketplace feed** — all collections, all event types:\n```\nGET /v1/public/market/events?limit=50\n```\nCross-collection event stream. Useful for marketplace-wide dashboards or analytics.\n\n## Incremental polling\n\nThis endpoint is designed for **incremental polling** — a lightweight alternative to webhooks.\nPass `since` with the timestamp of your last successful poll to receive only new events:\n```\nGET /v1/public/market/events?token=0.0.878200&since=2024-01-01T12:00:00Z\n```\nStore the `lastEventDate` from the response and pass it as `since` on your next poll.\nA 30–60 second polling interval is recommended.\n\n## Response fields\n\nEach event includes: `eventType`, `token`, `serialId`, `nftName`, `price`, `previousPrice`,\n`priceSymbol`, `sellerAddress`, `buyerAddress`, `eventDate`, `eventDateUnix` (UNIX timestamp),\n`transactionId` (formatted Hedera transaction ID), and `paymentToken` (address + symbol).\n","tags":["market"],"parameters":[{"in":"query","name":"token","schema":{"type":"string"},"required":false,"description":"(Optional) Filter events to a specific NFT collection token address in the form 0.0.N (e.g. \"0.0.878200\", ASCII digits, no leading zero).

If the collection has no active listings, the check is skipped.\n  - **With `requiredTraits`** → `orderPrice` must be ≤ the **safety ceiling** for the exact trait combo, computed as: `min(traitListingFloor, basis)` where `basis = 2.0× currentMaxOrder` for that trait combo (or `2.0× historicalMax` if no current collection offers exist). In plain English: pricing must be reasonable relative to other active collection offers, and may never exceed the cheapest listing for the trait. The error names which signal capped the ceiling.\n- If you intentionally want to exceed either ceiling, contact support.\n\n**Permission required.** Turn on \"Manage Collection Offers\" for your key at\nhttps://sentx.io/profile/settings?tab=api (SentX API tab, API Permissions). Your\nwallet asks you to approve the change. Without it every request answers 401.\n\n**Setup Steps:**\n1. Generate an API key from https://sentx.io/profile/settings?tab=api\n2. Turn on \"Manage Collection Offers\" for that key; your wallet asks you to approve the change\n3. Use the API key in the `apikey` query parameter for this endpoint\n\n**Safe retries with Idempotency-Key:**\nSend an `Idempotency-Key` header with a new unique value for every new request (a UUID works), and send the SAME value when you retry that request. SentX keeps each key for 24 hours, scoped to your API key and wallet.\n- Same key and same body after the first request finished: you get the first answer again, marked `idempotentReplay: true`, and nothing is placed twice.\n- Same key while the first request is still running: 409 with `idempotencyStatus: \"in_progress\"`. Wait `retryAfter` seconds and retry with the same key.\n- Same key with a different body: 422 with `idempotencyStatus: \"key_reused\"`. Use a new key for a new request.\n- First request refused before anything was placed (for example not enough balance): a retry with the same key runs again.\n- First request failed after it started placing collection offers: a retry gets 409 with `outcomeUnknown: true`. Check GET /v1/user/orders/list and use a new key only if you still want the offers.\n- No answer from the order service, or a 502, 504, 520 to 524 or 530 on the way (load balancer or Cloudflare): 503 with `outcomeUnknown: true` and the key to retry with in `idempotencyKey`.
