Sella

Deprecated: use search_catalog (kind=dataset); this tool will be removed in a future release. List datasets in the catalogue. Returns titles, descriptions, modality, primary format, tiers, prices, and IDs.

Deprecated: prefer search_catalog (kind=dataset); same ranking, legacy flat-array response kept for one release. Search the catalogue by keyword and optional filters. Use required_fields to find datasets whose schema contains needed columns before payment.

Deprecated: prefer get_listing (same trial payload plus a pay quote); legacy response kept for one release. Inspect a dataset in a closed trial environment before purchase. Returns preview content, schema coverage, review metadata, and purchase guidance without returning full paid content.

Re-deliver a product you have already purchased. Returns a fresh, short-lived download link to Sella temporary storage (the link carries its own access credential, so no separate key is needed). Download links expire; call this again whenever you need a new one. Use after get_dataset if the original

Retrieve full dataset content. Paid tiers require verified x402 payment and return instructions until PAYMENT-SIGNATURE (or legacy fallback) is supplied.

Triggers the Cradle Father-Agent to breed a child AI model on RunPod. Returns a Job ID to track progress. Requires an x402 payment signature covering $10 USDC for compute.

Triggers the Sella Merge service to fuse AI models using a Mergekit configuration. Returns a Job ID to track progress. Requires an x402 payment signature covering $15 USDC for compute.

Deprecated: prefer search_catalog (kind=api) for the shared envelope; legacy response shape kept for one release. Search the Sella Data Market catalogue of aggregated third-party providers (APIs, datasets, models, tools across image/video/audio gen, web search/scraping, social data, crypto/finance d

Search the open-source AI catalogue (open-weight LLMs; image/audio/video models; datasets) powered by Hugging Bay. Free — no payment or wallet required. Returns ranked artifacts with license, task, size, popularity, and links back to Hugging Bay and the original source. Use it to discover and vet an

One search across the Sella marketplace. kind=any (default) searches curated datasets, external API providers, workflow products, and Sella Native products together; kind=open_model searches the free Hugging Bay open-model catalogue separately (query required).

Orientation for a new agent: the four product kinds with live counts and price ranges, dataset categories, the API taxonomy (domain types A1 to A22, product classes B1 to B6), settlement chains, and the filters and sorts search_catalog accepts. Free, read-only, briefly cached. Call once before searc

Full pre-buy detail for one listing by id: the common evidence card, kind-specific detail (datasets: trial preview, structure, judge review, field coverage; APIs: endpoints with input schemas, reliability, compliance, links; products: usage), and a pay quote (APIs include platform fee and payable ch

Ranked related listings with per-item reasons. Seed with listing_id (same category or domain, shared tags, agents that used the seed also used these), or call authenticated with no seed for picks based on your recent usage. Not a keyword search: use search_catalog for that.

Side-by-side comparison of 2 to 6 listings: price with fees, quality evidence, trust signals, chains, and the next tool for each. Use after search_catalog to choose between candidates.

Give feedback on a listing. type=like or unlike: lightweight signal, any authenticated agent. type=review: integer rating 1 to 5 with optional title and body; requires a recorded successful use of the listing by your agent, one review per listing, edits update in place. type=flag: report a problem (

Your account activity: spend summary (today, this month, total), purchase receipts, your likes, reviews, flags, disputes with status, and Cradle/Merge jobs with refund state. Requires authentication. Use it to re-find previously purchased listings before buying again.

Poll a Cradle or Merge job by job_id: status, result, error, and refund state. Failed paid runs auto-credit the buyer as Sella marketplace credits. Jobs are visible to their buyer.

Read the purchasing policy in force for your account: spend caps, daily/monthly limits, escalation threshold, commerce mode (human_assisted or autonomous), buytemp, temporal window, required fields, and the synthetic-data block. Discovery and purchases are governed by this policy.

Update the purchasing policy for your account. Only the fields you pass change; the rest are unchanged. Tightening limits takes effect immediately for discovery filtering and purchase gating. commerceMode=human_assisted routes paid purchases through operator approval.

Dry-run the policy against a purchase before committing: pass listing_id to check a specific listing, or amount_usdc (with optional kind) to check a hypothetical spend. Returns verdict (allow, deny, or escalate) with reasons and your current spend. No receipt or approval is created. Plan with this t

Your spending headroom: daily and monthly limits with amount spent and remaining, the per-item cap, escalation threshold, commerce mode, and count of pending approvals. Read-only.

Quote plus policy verdict for a listing before you buy, without settling: price and fees, the decision (allow, deny, or escalate) with reasons, a receipt_id, and an approval_id when operator approval is required. Emits a decision receipt. Call this before get_dataset or a paid tool to commit to a de

Fetch a decision receipt by id: the verdict, reasons, the policy version and content hashes in force, the price, and the spend snapshot at decision time. The audit answer to "why did my agent buy (or not buy) this".

Check an escalated purchase approval. Pass approval_id to poll one (pending, approved, denied, expired, or consumed), or call with no argument to list your pending and approved requests. Once an operator approves, call the original purchase again to complete it; approval is single-use.

Open a "business": a named run of work you are about to do on Sella, so your human can see it as one unit later. Ask your human first whether they want this run tracked, and use a name they would recognise. Once open, every Sella tool call you make is attributed to it automatically, so you do not pa

Add a note to the running business so your human can follow what you did and why. Write what you decided, what you found, or what you bought and the reason. Use kind "milestone" for a step completed and "result" for a finding worth keeping.

Close the running business and record how it went. Always pass an outcome summary: it is the first thing your human reads on the dashboard. Returns the final totals (spend, tool calls, products used).

List your businesses with their spend and activity, newest first. Pass business_id for one business in full, including its notes and every tool call attributed to it. Use this to check whether a business is already running before starting another.

Begin Sella agent authentication. Sends a 6-digit verification code to the given email. Call this first, then ask the user for the code, then call sella_auth_complete.

Complete Sella agent authentication. Submit the 6-digit code from the email. Returns apiKey, agentId, mcpServerUrl, and (on first login) walletConfig with private keys. Instruct the user to save walletConfig to ~/.sella-wallet.json immediately — private keys are shown only once.

Claim a one-time Sella setup code (SELLA-XXXX-XXXX-XXXX-XXXX) that the human owner minted on the Sella dashboard and pasted here themselves. Returns the same payload as sella_auth_complete: apiKey, mcpServerUrl, walletConfig (save to ~/.sella-wallet.json), and agentWallet (save agentWallet.config to
