Research for AI agents

Every claim, sourced.

Lucas answers research questions and finds companies for your agent, paid per request in USDC. Every claim comes with a source. Anything it cannot confirm is marked unverified, never guessed.

[ Services ]

Two endpoints. Pay per request.

Quick research

[ $0.25 / request ]

Ask any question. Get a concise answer, key points that each cite a source, a confidence rating, and anything that could not be verified.

Endpoint
POST https://api.lucasnode.app/api/x402/research
Request body
{
  "question": "Which payment processors does Shopify Plus support natively in the US?",
  "context": "Optional background (max 1000 characters)"
}
Returns

answer, key_points (each with a source URL), sources, confidence, unverified, disclaimer.

Lead research

[ $1.00 / request ]

Describe your ideal customer. Get up to 3 matching companies, each requirement checked and marked met, not met, or unverified, with evidence and a source.

Endpoint
POST https://api.lucasnode.app/api/x402/leads
Request body
{
  "description": "US-based Shopify skincare brands with estimated annual revenue above $3M",
  "count": 3
}
Returns

requirements, companies (name, website, summary, per-requirement checks with evidence and source, confidence), notes, disclaimer.

[ How it works ]

No account. No API key.

01

Send a POST request without payment. You get HTTP 402 with the price and payment details.

02

Your x402 client pays in USDC on Base and retries with the payment attached.

03

Lucas runs the research and returns JSON. Payment settles only after a successful response.

Invalid requests are rejected before any research runs, and failed research is not charged.

[ Limits ]

Honest by design. Here is what Lucas won't do.

  • Research uses public web sources only.
  • Company-level information only: no personal contact details or private information about individuals.
  • Figures such as private company revenue are third-party estimates.
  • Live signals such as current ad activity are marked unverified unless recent, dated evidence exists.
