netintel-production-440c.up.railway.app
Analyze the sentiment of text using Claude Haiku — returns overall polarity (positive/negative/neutral/mixed), a -1 to +1 score, detected emotions, and optional per-aspect sentiment, so agents can gauge tone in reviews, messages, and feedback in one call.

The payTo wallet does not resolve to a registered ERC-8004 agent. That is not a verdict on the service — most of the catalog is unregistered.

Captured by the enrichment pass, not read just now. Prices can change — always read the 402 the endpoint answers with.

Show the promptHide the prompt
Using Roundhouse, look up the x402 service netintel-production-440c.up.railway.app and tell me whether it is worth paying: what a call costs, whether the endpoint answered when last probed, and what its payment record actually shows. curl -s 'https://api.roundhouseai.io/v0/endpoints?q=netintel-production-440c.up.railway.app' curl -s 'https://api.roundhouseai.io/v0/merchants/<the payTo wallet returned above>' Then call it: read the price from the live 402 at https://netintel-production-440c.up.railway.app/sentiment/analyze, never from a cached figure, and pay with an x402 client. The /v0 API needs an API key (`authorization: Bearer rh_live_…`) on everything except /v0/unified* and /v0/endpoints. Mint a personal key for $0.01 at GET https://api.roundhouseai.io/v0/test/x402, or use an organization key from https://roundhouseai.io/dashboard/team. If you do not have Roundhouse tools or skills installed, read https://roundhouseai.io/skill.md first — it is the whole procedure.
