Testril

A Universe of
Blockchain Data

For agents. They pay for what they need. Nothing else. No signups. No commitments.

A universe of blockchain data
Built for agents

How it works

From question to verified data

Step 1 / ask

Ask what you want

Create new data or retrieve existing data.

Step 2 / get a quote

Get the price up front

Testril returns a detailed bill.

Step 3 / pay

Pay for the work

We support x402, exact and batch-settlement. Settle on Polygon, Arbitrum One, Base, and World Chain.

Step 4 / verify

Wonder where the data came from?

Ask for provenance. We'll tell you where the data came from and how we computed it.

The problem

Agents don't need raw blockchain data

Agent pays too much

Raw blocks, logs, and traces create a huge context. Agents pay to ingest and then to reason over all that data.

APIs lack data coverage

If your question fits an existing endpoint, you're fine. If it doesn't, you're stuck. APIs were built for humans.

Data cannot be audited

Agents have to trust the data they work with. Without provenance they can't verify anything.

With Testril

93–99%*

fewer inference tokens per answer than an agent crunching raw data.

70+

supported chains. Ask any question about what happened on any of them.

100%

of values traceable to source data and the code that produced them.

* Range across internal benchmark queries: a Testril endpoint versus an agent computing the same result over raw indexed tables.

The architecture

Compute and store only what's needed

Index everything

Traditional Model

Compute and store everything, just in case.

  • Compute and storage used for data no ever asks for
  • Schemas are fixed at indexing time, so new questions need a new pipelines
  • Data interpretation falls to the agent, at inference prices
  • Data isn't auditable

Index on demand

Testril Model

Compute and store only the data agents ask for.

  • No data is indexed or stored unless it's needed
  • Data is organized by internal agents, as needed
  • Agents receive answers, not piles of data to analyze
  • Data source and transformations available for all data

What becomes possible

If it happened on chain, your agent can ask about it

Stablecoins

Flow analysis

Compare USDC and USDT volume across any block range and keep the numbers current.

Liquidity

DEX monitoring

Track pool changes, net liquidity, asset exposure, and protocol activity.

Wallets

User cohorts

Find wallets by behavior, value, or activity.

Risk

Exposure checks

See which wallets or protocols touched a given asset, pool, bridge, or contract.

Reporting

Metrics

Feed current, verifiable numbers into products, dashboards, and internal reports.

Research

The unexpected question

Ask the thing nobody built a dashboard for. If the data is on chain, it's within reach.

Who it's for

Built for agents.

SI agent teams

Give agents live and historical chain data without loading raw data into every request.

agentstoolsworkflows

dApps and protocols

Power custom metrics, alerts, liquidity views, and reporting from a single endpoint.

appsanalyticsmonitoring

Financial products

Use current, verifiable chain data for risk, research, and reporting.

FAQ

Common questions

Is this an MCP server?+

No. Testril is a data network. MCP is the interface into the network.

Is this another blockchain indexer?+

Yes, in a sense. Traditional indexers prepare datasets before anyone asks. Testril starts with the question and computes on demand, so nothing is computed or stored until someone asks for it.

Why not just point an MCP at indexed data?+

Three reasons:

  1. Using raw data is expensive!
  2. APIs are pre-organized, but maybe not the way you need.
  3. Index and API data isn't auditable.
How does pricing work?+

You get a quote before anything runs. Pay to index and pay to query. If you index, you get paid any time someone queries your data. Payments settle on Polygon, Arbitrum One, Base, and World Chain. No subscription required.

Can I get real-time data?+

Yes. For data you need on an ongoing basis. You just prepay for future indexing. As new blocks finalize, they are automatically index.

How do I know the data isn't hallucinated?+

Every answer is auditable: both the provenance of the raw data and any transformation code that produced it.

Which chains are supported?+

70+ chains. If your agent doesn't find the chain it needs, it can request it.

How do I get paid for indexing data?+

When you index data, an NFT gets dropped into your wallet. As people query your data, you earn. Got to our claim page any time to see what you've earned and claim it.
