Your gateway
to Base.

1. 1

   Discover a candidate

   Browse selected Base pools with liquidity and observation dates. A listing is a starting point for research, not a safety assessment.

   Explore discovery
2. 2

   Inspect the evidence

   Check a token’s trading restrictions, taxes, permissions and more. Missing data and risk warnings remain visible in the report.

   Open token inspector
3. 3

   Save and revisit

   Keep dated reports in this browser and compare observations later. Saving is free; each new inspection is a separate purchase.

   Open my research

Discovery and inspection are separate purchases. Automated checks can miss risks; a completed check does not guarantee safety.

Price previews are free. Reports may use cached data and keep their original observation time. Nothing runs or charges automatically in your browser.

Connect your agent to the same data.

Use HTTP or MCP to request onchain data. Start with a free price quote; enable payments only when you are ready. This demo quotes fresh-pool data, a separate API product.

Watch a full run that was already paid for → A pool eight seconds old, a verdict on its token, and both settlement transactions linked so you can check them.

console.log(await client.getPaymentQuote(

Twenty-one endpoints, priced per call

Base onchain data first — gas, any token by contract address, wallet portfolios, address analytics, DEX pools and a spam-filtered new-token radar — plus market and Turkish-lira feeds.

Selected responses are cached; lifetimes vary by source. Handler failures before settlement are not billed. If a signed request times out or its response is lost, inspect the receipt and wallet before retrying: settlement may already have happened.

Ask only for what changed

A snapshot is useful once. Agents that run on a schedule want the diff. Address and radar watches return a cursor; send it back as ?since=. Drain address pages while hasMore is true and deduplicate transaction hashes. Radar coverage is partial; the price watch checks a threshold and has no cursor.

# inspect the quote — no wallet or payment
curl -i "https://agenttoll.app/api/watch/radar"
HTTP/1.1 402 Payment Required

# after payment via the bounded client or MCP tool,
# pass the returned cursor unchanged to the next call:
# /api/watch/radar?since=<returned-cursor>
# Each paid poll costs $0.003, including an empty result.
# Results cover the current ranked listing, not every pool.

One request, one micropayment, one response

Plug it straight into Claude

AgentToll ships an MCP server. Add it to Claude Desktop or Claude Code and use 21 data tools plus two free quote and budget tools. Start without a wallet; add a dedicated wallet and a finite session budget when you want to pay.
