Use it to find credible new Base launches, investigate a token, or compare Base projects. The paid endpoint returns evidence, market-quality analysis, risk flags, exclusions, a ranked conclusion, source links, and researchedAt. The first HTTP 402 response is the payment challenge, not a failure: an x402-compatible client must sign the $0.01 USDC authorization and retry the request. Plain fetch or curl stops too early.
