Fetch JSON from a saved PulpMiner API

pulpminer_fetch_api_data
Idempotent

Retrieve JSON from a saved PulpMiner API by numeric ID; supply variables for dynamic endpoints via POST.

Instructions

Call a saved PulpMiner API and return its JSON (GET /external/{apiId}, or POST with variables for dynamic APIs). Uses the PulpMiner API key (PULPMINER_API_KEY locally, or Authorization: Bearer <key> on the hosted server). Costs 0.4 credits (+0.1 if the API renders JS); cached APIs return fast.

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

{
  "id": 1,
  "jsonrpc": "2.0",
  "method": "tools/call",
  "params": {
    "arguments": {
      "apiId": "<apiId>"
    },
    "name": "pulpminer_fetch_api_data"
  }
}

Input Schema

NameRequiredDescriptionDefault
apiIdYesNumeric API id, the value after /external/ in the API URL (e.g. 566).
variablesNoOnly for dynamic APIs: values for every {{ variable }} in its dynamic URL, e.g. {"query": "laptops"}.

A3.7/5.0
Behavior4/5

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

Annotations already declare openWorldHint, idempotentHint, non-read-only and non-destructive, but the description adds real behavioral context the annotations lack: cost (0.4 credits, +0.1 for JS-rendered APIs), caching speed, and the auth mechanism (PULPMINER_API_KEY locally or a Bearer token on the hosted server). It does not cover error behavior or rate limits, so not a 5.

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

Conciseness4/5

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

Three tightly packed sentences, front-loaded with purpose, then invocation/auth, then cost — no filler. The middle clause partly restates schema content (variables only for dynamic APIs), which is the only minor redundancy.

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?

With no output schema, the description correctly states the return (its JSON) and covers the notable complexities an agent must budget for: dual GET/POST modes, authentication, per-call credit cost, and caching. It omits failure/error behavior, which keeps it short of 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 description coverage is 100%, so apiId and variables are already fully documented with patterns and examples; the description's restatement ('POST with variables for dynamic APIs') adds little. Baseline 3 is appropriate when the schema does the heavy lifting.

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 opening sentence gives a specific verb (call/fetch) and resource (a saved PulpMiner API returning JSON), so the agent knows exactly what the tool produces. It is naturally distinct from list_saved_apis and save_as_api, but it never names or explicitly contrasts a sibling, so it falls short of the 5 bar.

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

Usage Guidelines3/5

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

The description distinguishes GET (plain call) from POST with variables (dynamic APIs), which is useful invocation context. However, it gives no tool-selection guidance against siblings such as list_saved_apis (to find an apiId) or generate_json, and states no prerequisites beyond implying the API must already be saved.

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