Chart blockchain activity

portal_get_time_series

Read-only

Retrieve chart-ready time-series metric buckets for blockchain activity, enabling period-over-period comparisons and grouped EVM contract trends across supported networks.

Instructions

Build simple activity charts and other time-series views across supported VMs, including compare-previous windows and grouped EVM contract trends.

COMMON USER ASKS:

Base transactions per 15m bucket
Compare two periods

FIRST CHOICE FOR:

activity over time, compare-current-vs-previous, grouped trends, and simple activity charts

WHEN TO USE:

You want chart-ready metric buckets over time.
You want a simple activity chart for a network, defaulting to a 6h interactive window unless a longer window is explicitly requested.
You want to compare the current period to the previous period.

DON'T USE:

You need raw record lists instead of aggregated buckets.
You need DEX pool candles or OHLC output.

EXAMPLES:

Base transactions per 15m bucket: {"network":"base-mainnet","metric":"transaction_count","duration":"6h","interval":"15m"}
Compare two periods: {"network":"solana-mainnet","metric":"transaction_count","duration":"1h","interval":"5m","compare_previous":true}

First observedv0.7.9Jun 25, 2026

TDQS

A4.6/5.0

Behavior4/5

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

Annotations carry the safety profile (readOnlyHint=true, destructiveHint=false), lowering the bar. The description adds useful behavioral detail: defaulting to a 6h interactive window, compare-previous windows, and grouped contract trends. It does not cover output format, but an output schema is present, so that gap is acceptable.

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?

The description is well-organized with clear headers and a logical flow, but it is somewhat lengthy. Each section arguably earns its place, and the front-loaded purpose sentence gives immediate orientation. Slight redundancy between 'FIRST CHOICE FOR' and 'WHEN TO USE' prevents a perfect score.

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

Completeness5/5

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

For an 11-parameter tool with 3 required params, the description covers common use cases, exclusions, examples, and behavioral defaults. Since an output schema exists, return-value details are not required. The description, combined with the rich schema and annotations, gives an agent everything needed to select and invoke this tool correctly.

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 baseline is 3. The description goes beyond the schema by providing two concrete JSON examples that demonstrate realistic parameter combinations, including network shorthand, interval buckets, duration defaults, and compare_previous. This practical grounding helps agents assemble correct calls.

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 opens with a specific verb-resource combination—'Build simple activity charts and other time-series views'—making the core action and resource unmistakable. It also distinguishes itself from sibling tools by explicitly excluding DEX pool candles and OHLC output, which separates it from portal_evm_get_ohlc.

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?

It provides 'WHEN TO USE', 'DON'T USE', and 'FIRST CHOICE FOR' sections, giving clear selection guidance. The 'DON'T USE' clause explicitly excludes raw record lists and OHLC candles, effectively routing agents toward alternatives like portal_get_recent_activity or portal_evm_get_ohlc without naming them directly.

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