Sprime – weather, crypto, news, forex all normalized to one JSON schema

In plain words

Sprime is a unified API gateway that normalizes data from 15+ providers—weather, crypto, news, forex, air quality, geocoding, and more—into a single JSON schema. Developers use one API key to access consistent responses across all endpoints, with automatic failover if a provider fails. It targets developers tired of writing custom adapters for each API's different field names and formats. The free tier offers 500 requests per day.

Build with PROOFGATE on sprime.us. API keys, dashboard, docs, and sandbox access for privacy-preserving age and eligibility verification.

Use Sprime's existing keys, dashboard, docs, and sandbox to test privacy-preserving age and eligibility checks. sprime.io stays the buyer-facing PROOFGATE front. Use this host for API contracts, key management, traffic inspection, and sandbox runs. The buyer story stays on sprime.io. GET /v1/credentials/request?profile=age_over_18 Returns: - nonce - requestId - client_id for this host - response_uri for this host Verify Wallet presentation POST /v1/credentials/verify Checks: - nonce is single-use - aud matches the stored origin - trusted issuer is pinned - only the requested predicate passes A successful response returns pass/fail plus a non-reversible audit token.

In the maker’s words, at launch

I kept rewriting the same JSON normalization glue for every side project. Weather APIs return different field names, crypto APIs have inconsistent structures, news APIs format dates differently — and you end up writing adapters for all of it before you can even start building. Sprime is a unified API gateway that…

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  Hello my name is Ben Ward for the past 3 years I have been remastering the financial game Wall Street Raider created by Michael Jenkins originally on DOS in 1986. It has been a rough journey but I finally see the light at the end of the tunnel. I just recently redid the website and thought maybe the full story of how this project came to be would interest you all. Thank you for reading.
