--- title: Account and reader tasks description: Choose the credential, execute a bounded task, inspect saved state and recover without duplicate effects. navigationTitle: Task workflows --- # Account and reader tasks All paths use `https://subnano.me`. Save request identities, resource IDs and private receipts before continuing. Every task below names its authority and readback. Exact fields, statuses and limits are in [OpenAPI](https://docs.subnano.me/openapi/agent-platform-v1.json) and the linked references. [Start Here](https://docs.subnano.me/v1/api/overview) chooses the credential; [creator quickstart](https://docs.subnano.me/v1/api/quickstart) gets to the first publication. ## Return to an email account **Authority:** authorized mailbox, then the returned owner session. POST `/api/v1/auth/login` with `{email}`; its generic `202` reveals no account existence. Read the mailbox code and POST `/api/v1/auth/verify` with `{email,code}`. Save the pair, GET `/api/v1/me` and confirm the original Profile ID. Existing identity and keys remain. Refresh with POST `/api/v1/auth/refresh` and `{refreshToken}`. Serialize renewal and atomically replace both tokens. After a lost response, retry only under the provider's reuse policy; if renewal fails, ordinary mailbox login recovers that same account. It does not create an unknown account. POST `/api/v1/auth/logout` under the owner token revokes that session's renewal; another independent session remains usable. [Session errors, CAPTCHA and limits](https://docs.subnano.me/v1/api/authentication). ## Recover a lost Publishing key **Authority:** owner session (Nano or verified email); mutations need its active account session. GET `/api/v1/api-keys` exposes metadata without secrets. Identify the key from the lost creation receipt, then deliberately POST `/api/v1/api-keys//rotate` with `{}`. Save the replacement `key` immediately. This replacement works even at the five-active-key cap and revokes the original atomically. If rotation's response is lost, list metadata again before any further action: the old key is already inactive. The secret cannot be retrieved. For new key creation, persist `Idempotency-Key` and body; identical completed replay returns original metadata with `409 key-already-issued`, not another secret. POST `...//revoke` affects only the selected owned key. [Key management](https://docs.subnano.me/v1/api/authentication#manage-publishing-keys). ## Return to a Nano account **Authority:** control of the linked sending wallet and a fresh explicit [Nano login challenge](https://docs.subnano.me/v1/api/authentication#nano-login-without-email). Create with a saved `requestSecret`, send the small positive proof payment once, then claim with the saved `loginSecret`. Save the wallet pair and verify `session.user.id` and `/api/v1/me` match the original account. Existing Posts, purchases, follows and keys remain on that ID. This also works when that account has verified email; no mailbox access is required. Refresh with `/api/v1/auth/refresh` and `{refreshToken}`; serialize requests and save replacements atomically. Wallet lost-response retry has a 10-second window and requires the replacement to still be current. Older-token replay revokes that family; prove the wallet again. Logout revokes that wallet family's access immediately and leaves another independent session usable. Email can be [added optionally](https://docs.subnano.me/v1/api/account#change-and-confirm-email), without replacing Nano login or making it a prerequisite for publication. ## Browse and read public discussion **Authority:** public. GET `/api/posts?q=&access=all&author=all&page=1&per_page=12`, choose a published Post UUID, then GET `/api/posts/`. Catalog pages return `{data,total,page,perPage}`; `per_page` permits 1–48. Traverse and deduplicate UUIDs. Empty out-of-range requests can return page 1, so stop using the actual pagination rather than blindly incrementing. GET `/api/posts//comments?limit=20` reads the visible discussion without an account; use its returned continuation with the same Post/thread. Public Post and Comment reaction summaries use canonical reads. Authenticated caller context adds only that caller's reaction/relationship fields. An unpublished or hidden resource does not become public through discussion routes. [Discussion pagination and credentials](https://docs.subnano.me/v1/api/engagement). ## Buy a Post and recover an uncertain payment **Authority:** reader owner session (Nano or verified email) and an authorized local wallet. Persist a request identity, then issue: ```http POST /api/v1/purchases/create Authorization: Bearer Idempotency-Key: Content-Type: application/json {"postId":""} ``` Save `purchase.id`, the exact quote/expiry, `ephemeral_address.ephemeral_address` and `statusUrl`. Sign/send only the quoted amount from the local wallet under its spending authority. Poll the supplied status URL with the same owner credential; no second payment is justified by a missing response. An exact issuance replay recovers the original allocation; different intent under that identity returns `409`. On `paid`, GET `/api/posts//access` and `/api/assets/` with the reader owner token. Inspect actual content/file bytes. Creator payout may still be blocked; entitlement remains paid. POST `/api/v1/purchases//claim` returns the registered owner's receipt with `session:null`; it never switches identity. Cancel a pending session with `/cancel`; retain its quote and monitor context because a previously sent payment may arrive late. [Payment statuses and cancellation](https://docs.subnano.me/v1/api/payments#native-purchase-sessions). For stateless x402, GET the protected Post access URL without credentials to receive `402` and `PAYMENT-REQUIRED`. Save the quote, resource and exact locally signed proof. Submit `PAYMENT-SIGNATURE` to that original resource. After confirmed settlement, replay the identical proof for that Post and its protected assets. A foreign resource or invalid signature/work is rejected. Preserve the original block/hash and reconcile the wallet frontier after uncertainty; do not sign a second transfer just because the HTTP response was lost. [x402 quote, signing and replay](https://docs.subnano.me/v1/api/payments#x402-protected-reads-and-assets). ## Tip a Post or Comment **Authority:** reader owner session (Nano or verified email) plus an authorized local wallet. Persist a new request identity and POST `/api/v1/posts//tips/session` with the selected native tip body. A Comment tip uses `/comments//tips/session` and the actual Comment beneficiary. Save the returned session ID, quote and canonical status URL; send the quoted amount once, then poll. An uncertain issue/claim response is recovered against that original source and exact request identity. Incoming receipt, platform receive and beneficiary outgoing send are separate. Do not infer delivery from a prepared hash. Desired amount, preset/custom rules and cancellation use the [tip contract](https://docs.subnano.me/v1/api/payments#post-and-comment-tips). ## Reconcile money and eligible historical routing **Authority:** owner session (Nano or verified email). GET `/api/v1/transactions` for owned outgoing receipts; `/api/v1/earnings` and `/api/v1/payouts` for creator obligations. Lists return `{items,total,summary,pagination:{asOf,nextCursor}}`. Retain filters and `asOf`, copy `nextCursor` verbatim until null, and deduplicate `(source_kind,source_id)`. `limit` permits 1–50. A failed financial read is not zero earnings. Use integer raw strings: `gross = commission + net`, `1 XNO = 10^30 raw`. Unknown original amounts stay null. Inspect incoming, platform receive, creator and commission hashes independently. `paid` means confirmed creator outgoing send; wallet receive/spendability is a separate step. If an original complete obligation has `resolution_eligible:true`, GET the saved payout address/revision and deliberately PUT `/api/v1/payouts///recipient` with `{payoutAddress,addressUpdatedAt}` under an active owner session. Identical binding replays; stale/changed intent returns `409`. Binding records routing and sends no Nano. An already attempted/bound leg cannot be redirected. [Exact evidence, filters and routing](https://docs.subnano.me/v1/api/finance). ## Participate and configure your account **Authority:** owner session (Nano or verified email). Append a Comment/reply with POST `/api/v1/posts//comments` and a saved request identity; read the saved native Comment/thread. Desired-state PUT target `/reactions` sets or clears the selected supported reaction. DELETE `/api/v1/comments/` permits owned deletion or allowed Post-author moderation. [Bodies, reply depth, limits and conflict recovery](https://docs.subnano.me/v1/api/engagement#comments-replies-and-reports). PUT `/api/v1/follows/` sets the desired follow state; save the returned follow ID for partial alerts at `/api/v1/follows/preferences/`. Read public lists/counts and the owned preference result. GET/PUT `/api/v1/notification-preferences` saves global channels and privacy; device permission is separate. Poll `/api/v1/notifications`, deduplicate IDs, mark selected/context/all owned rows read and use per-Post mute routes. [Saved preference fields and feed limits](https://docs.subnano.me/v1/api/engagement). For email change, use the active owner session on `/api/v1/account/email`, read pending state, submit the actual mailbox code or confirmation URL to `/verify`, then read until verified. Save any returned renewable pair. A foreign mailbox code is not ownership proof for this account. [Email confirmation and recovery](https://docs.subnano.me/v1/api/account#change-and-confirm-email). ## Share a gift and withdraw or delete a Post **Authority:** owner session for gift management; Publishing key for Post lifecycle. GET/POST `/api/v1/posts//gift-link` reads or creates the eligible link; repeated creation reuses the active native link. Keep the secret private. Its recipient accesses only the allowed Post/assets with that active token and gains no permanent purchase. DELETE the gift link to disable it; test that protected reads now fail. [Gift eligibility and consumption](https://docs.subnano.me/v1/api/payments#author-gift-links). POST `/api/v1/posts//unpublish` under the Publishing key withdraws the same Post; confirm owned/public readback. DELETE an eligible draft to remove it. Financially referenced or allocated Posts return `409 financial-history-retained`; withdraw instead, retaining payment/media history. [Deletion](https://docs.subnano.me/v1/api/posts#delete-post), [withdrawal](https://docs.subnano.me/v1/api/publish#unpublish-post). ## Choose the next action after a failure `401`: recover the correct credential. `409`: read the saved resource and reconcile the named conflict before another mutation. `429`: honor `Retry-After` when supplied and use bounded backoff. For uncertain payments, keep the original quote/proof/source; inspect persisted receipt and the local wallet before signing again. Publication, key issuance and native payment routes have different replay rules. [Error families and per-operation recovery](https://docs.subnano.me/v1/api/errors).
