What it does

This endpoint wraps the Exa "Find Similar" API through StableEnrich, a pay-per-request research gateway. Given a URL, it returns a list of semantically similar web pages ranked by relevance. The endpoint accepts a required `url` parameter and an optional `numResults` (1–100, default 5). Additional filtering is available via `includeDomains`, `excludeDomains`, date range filters (`startCrawlDate`, `endCrawlDate`, `startPublishedDate`, `endPublishedDate`), and text inclusion/exclusion arrays. A `contents` object lets you request full text, highlights, summaries, subpages, and extras like outbound links.

Pricing is $0.01 per request (fixed, in USD). Payment is handled via the MPP protocol using the Tempo method (pathUSD on Tempo L2) or x402 on Base mainnet. No API keys or subscriptions are required — payment itself serves as authentication. The endpoint is a POST at `https://stableenrich.dev/api/exa/find-similar`.

The response includes an array of result objects, each containing `title`, `url`, `publishedDate`, `author`, `score`, and optionally `text`, `highlights`, `summary`, `subpages`, and `extras`. A `costDollars` field reports the Exa-side cost. The full OpenAPI 3.1 schema is published with complete request and response definitions. StableEnrich is operated by Merit Systems and supports Base, Solana, and Tempo settlement networks.

Quality

0.88/ 1.00

Full OpenAPI 3.1 schema with complete request/response definitions and clear pricing ($0.01/request). The probe returned 405 on HEAD/GET which is expected since this is a POST-only endpoint. Comprehensive documentation is available in the guidance field. No live 402 challenge was captured for this specific endpoint, but the OpenAPI x-payment-info confirms pricing and protocols.

Warnings

  • —Probe returned 405 because HEAD/GET were tried on a POST-only endpoint; this does not indicate the endpoint is down
  • —No direct 402 challenge was captured for this endpoint during probing
