AgentData — crypto market data with a checkable record

OverviewDiscussionsAdmin

get_new_memecoins

New memecoin pools on Solana or Base, screened every 15 minutes ($0.010 USDC): each with its risk verdict, the market at screening time and whether its 7-day claim has resolved. The same population the public track record is computed from.

Tool call template

This tool declares no required parameters. Add optional parameters from the input schema as needed.

{
  "id": 1,
  "jsonrpc": "2.0",
  "method": "tools/call",
  "params": {
    "arguments": {},
    "name": "get_new_memecoins"
  }
}

Input Schema

NameRequiredDescriptionDefault
chainNosolana
hoursNolook-back window, 1-72
paymentNoOptional. Base64 x402 payment payload you signed yourself (ERC-3009 TransferWithAuthorization, USDC on Base). Call without it once to receive the payment requirements, sign those, then call again with this argument. This server forwards the payload and never holds a key.

A3.6/5.0
Behavior4/5

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

With no annotations, the description carries the burden and does a good job: it reveals the 15-minute screening cadence, the $0.010 USDC cost, the output fields, and the relationship to the public track record. It does not explicitly state that the operation is read-only or describe side effects, but that is less critical for a 'get' tool and the payment behavior is covered in the schema.

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?

Two tight sentences with no filler. Key facts—scope, frequency, cost, and returned fields—are front-loaded, and the provenance sentence about the public track record adds useful context without bloating the description.

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?

Despite having no output schema and no annotations, the description mentions the main returned data points and operational constraints. It does not explain pagination, response format, or error cases, but for a straightforward read tool with three optional parameters, it is reasonably complete. Slightly more explicit when-to-use guidance would make it fully complete.

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

Parameters3/5

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

Schema coverage is 67%, with chain and hours already described and payment given a detailed explanation. The top-level description adds contextual meaning around the chain ('Solana or Base') and implies the payment cost, but it does not materially improve parameter understanding beyond what the schema already provides. This is adequate but not exceptional.

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

Purpose4/5

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

The description clearly states the resource: new memecoin pools on Solana or Base, and specifies the returned contents (risk verdict, market at screening, 7-day claim status). It does not use an explicit verb like 'returns' or 'lists', and it does not directly contrast itself with sibling tools such as get_memecoin_risk, so it is clear but not fully differentiated.

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

Usage Guidelines2/5

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

There is no guidance on when to use this tool versus alternatives, no exclusions, and no mention of what get_memecoin_risk or other siblings should be used for instead. The notes about screening frequency and payment cost provide context, but not selection criteria.

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