BlockVectra: multi-chain RPC & Data API

by com.blockvectra
OverviewDiscussionsAdmin

Get Method Information

get_method_info
Read-only

Inspect a single method's chain-by-chain availability, Compute Unit (CU) weight, price per million calls, and documentation link. Check JSON-RPC method policy and Data API dataset coverage separately. JSON-RPC follows methods.allow and methods.deny from /v1/chains. Data API coverage follows data_features in GET /v1/status, with data enabled in /v1/chains. Pricing comes from /v1/plans. For the full system-wide pricing schedule and rate card, use get_pricing instead. For calculating projected bills for expected call volumes across methods, use estimate_usage instead.

Input Schema

NameRequiredDescriptionDefault
chainNoOptional chain slug (e.g. 'robinhood_mainnet'). If specified, only availability for this chain is returned.
methodYesMethod name (e.g. 'eth_call', 'eth_getBalance', 'debug_traceBlockByNumber', 'data.address_balances').

  3. Added

TDQS

A4.1/5.0
Behavior3/5

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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is clear. The description adds context about where policy/coverage/pricing data originates, which is useful. However, it does not describe return format or pagination/limits; with an output schema present this is less critical, but the description could disclose more about response shape.

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?

Front-loads the core purpose in the first sentence. The subsequent sentences provide useful routing and sourcing context, though the middle sentence about policy sources is somewhat dense. Overall efficient, but could be slightly tighter.

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 output schema exists, the description needn't explain return values. It covers what data is included, where it comes from, and when to choose siblings. One gap: it doesn't mention any authentication or permission requirements, though annotations suggest a safe read. Sufficient for correct invocation.

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 100%, so both parameters are fully documented in the schema. The description mentions that availability is chain-by-chain and that specifying a chain narrows results, but this largely repeats the schema's description of the optional chain parameter. Baseline 3 is appropriate.

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?

States a specific verb (Inspect) and resource (a single method), and enumerates the exact data returned: chain-by-chain availability, CU weight, price per million calls, and documentation link. This clearly distinguishes it from get_pricing (full schedule) and estimate_usage (projected bills).

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?

Explicitly names two alternatives and the conditions that select them: get_pricing for system-wide pricing, estimate_usage for projected bills. Also clarifies the separate policy/coverage sources for JSON-RPC and Data API, which helps the agent know when this tool's data applies.

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