Buy Aftermarket Domain

buy_aftermarket

Buy a taken domain that's listed for sale on an aftermarket (Afternic/Sedo) at its buy-now price, natively - no external site. Use when search shows a domain with for_sale.buyable = true. Always confirm the price with the user first. Pass max_price to cap it. If the listing is make-offer only (not buyable), use acquire_domain (broker) to negotiate instead. Crypto/USDC works like buy_domain (402 -> pay -> retry with payment_tx).

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
domainYesThe taken, for-sale domain to buy, e.g. kami.world
max_priceNoHard ceiling in USD. Defaults to the listing's buy-now price. The purchase is rejected if the live price is above this.
payment_txNoTx hash of a USDC payment already sent on-chain (step 2 of the USDC flow).
payment_chainNoChain the USDC payment was sent on. Required with payment_tx.
payment_methodNo'card' to charge the card on file, 'usdc' to pay with crypto.

A4.6/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the full burden and does well: it discloses the buy-now price cap via max_price, the USDC payment flow ('402 -> pay -> retry with payment_tx'), and the requirement to confirm price with the user. It doesn't fully detail error responses beyond 402, but the payment flow context is valuable.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is compact (four sentences) and front-loaded with the core purpose. Every sentence contributes: purpose, when to use, user confirmation, max_price, alternative tool, and crypto payment flow. No wasted words.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the lack of output schema and annotations, the description covers essential operational context: the buyable precondition, the cap mechanism, the alternative for non-buyable listings, and the payment flow. It omits specifics like success response or fees, but for the complexity of a buy action, it is largely complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the baseline is 3. The description adds meaning beyond the schema by explaining max_price as a hard cap, referencing the USDC flow with payment_tx/payment_chain, and noting payment_method options. This enriches understanding of how parameters interact.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's function: buying a taken domain listed on aftermarket at its buy-now price, natively. It distinguishes itself from siblings by specifying Afternic/Sedo, buy-now pricing, and the native (no external site) aspect, and contrasts with acquire_domain for make-offer listings.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Provides explicit when-to-use: 'Use when search shows a domain with for_sale.buyable = true' and when-not-to-use: 'If the listing is make-offer only (not buyable), use acquire_domain (broker) to negotiate instead.' Also includes a user confirmation step, giving clear operational guidance.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

A3.5/5.0
Disambiguation3/5

While most tools have distinct purposes, several clusters overlap significantly (e.g., check_email, check_email_deliverability, get_email_deliverability, get_domain_email_status; buy_domain, buy_aftermarket, acquire_domain). The descriptions are detailed and help differentiate, but the sheer number of tools makes it challenging for an agent to select the correct one without careful reading.

Naming Consistency3/5

The dominant pattern is verb_noun with underscores (e.g., create_mailbox, list_domains), but there are notable inconsistencies: destructive actions mix delete/remove/cancel/revoke/unsell, and a few names deviate entirely (search, dns_check, domain_status). The pattern is recognizable but not uniformly applied.

Tool Count1/5

With 122 tools, this vastly exceeds the 50+ threshold for extreme mismatch. Even for a comprehensive domain and email platform, the tool count is overwhelming and will likely hinder agent performance through excessive choice and context bloat.

Completeness4/5

The server covers a wide range of domains, DNS, email, marketplace, negotiations, transfers, webhooks, tokens, and billing. Minor gaps exist, such as no update operation for mail rules, no direct domain deletion, and limited mailbox configuration beyond forwarding and credentials, but most lifecycle workflows are supported.
