This is not our API. This repository is an independent, third-party profile of a company's publicly available API surface, maintained by API Evangelist. API Evangelist does not operate, host, resell, or support this company's APIs, and is not affiliated with or endorsed by the company unless stated on the profile.
Where the information came from. Everything here is assembled from material a member of the public can reach with a browser and no credentials — the company's own website, developer portal and documentation, the specifications it publishes for public use (OpenAPI, AsyncAPI, JSON Schema,
apis.json,llms.txtand similar), its public repositories, and its public status, pricing and changelog pages. Nothing here is obtained by breaching a system, defeating an access control, or using credentials of any kind.The rating is an independent assessment. The Kin Score and Agent Readiness rating are independently calculated scores of a company's public API artifacts, produced by API Evangelist against a published rubric. They are not certifications, endorsements, security assessments, or audits, and they score published artifacts — not the quality, safety, or security of the software.
Corrections, re-scores, and removal are free. No partnership, contract, or purchase is required, and you do not need to justify the request.
- Something wrong? Open an issue on this repository, or email info@apievangelist.com.
- Published something new? Ask for a re-score and we will re-run the rating.
- Want the listing taken down? Say so and we will honor it. The profile is reduced to your company name, a factual description, and a link to your own site, and the company is recorded as unrated — never scored zero for having asked.
Response times. Acknowledgement within one business day; removal or restriction within two business days; corrections and re-scores within five business days.
Not from the company, and here with a question? You are welcome here — we would rather be the front line and point you the right way than have a good report go nowhere. What this repository can answer is narrow, though, so it is worth knowing who you are actually looking for:
- A question about how the API works, an account, billing, or a bug in the service — that is the company's own support, not us. We profile this API; we do not operate it and cannot see your account.
- A bug in an open-source project we only catalog — file it on that project's own repository. This has happened with a real and correct bug report that reached us instead of the people who could fix it, which helped nobody.
- Anything about this listing itself — the description, the tags, the rating, a missing or wrong artifact — is ours. Open an issue here.
- Not sure, or something general about API Evangelist or APIs.io — open an issue on the APIs.io Inbox and we will route it.
This repository contains no software, and we will never ask you to download anything. There is no build, release, installer, or binary here — only text and machine-readable API descriptions, so there is nothing here that can be "corrupt" or need "repairing". Any issue, comment, or email claiming otherwise and offering a download link is not from us and is hostile. Do not follow the link; it is a lure. Report it to GitHub and, if you like, tell us at info@apievangelist.com so we can take it down.
On a security or compliance team? Email info@apievangelist.com with security in the subject line and you will get a person, not a form. We will tell you exactly which public URLs this profile was built from so your team can see the same surface we did, and we will take the listing down on request while you work through it.
Full detail: Where this data comes from
Yes Energy is a Boulder, Colorado power market data company serving the North American wholesale electricity markets — the seven ISOs and RTOs (ERCOT, PJM, MISO, CAISO, SPP, ISO-NE, NYISO) plus Canadian and Western markets. It aggregates, cleans, and enriches nodal locational marginal prices, FTR auction results, transmission and generation outages, real-time generation and flow telemetry, constraints, load, weather, and fuels data, and sells it through DataSignals (a REST API), DataSignals Cloud (Snowflake Secure Data Sharing), DataSignals Lake (bulk load into a customer warehouse), the PowerSignals and QuickSignals analyst front ends, EnCompass modeling, Live Power telemetry, Infrastructure Insights, Position Management, and bid-to-bill Submission Services. It sits in the private, commercial layer of the energy value chain: it does not generate, distribute, or retail electricity and it holds no consumer relationship — it resells and enriches public ISO/RTO market data to traders, IPPs, utilities, and asset developers. Its API posture is honestly closed: the DataSignals REST API is real and confirmed live at https://services.yesenergy.com/PS/rest/, but it answers every anonymous request with HTTP 401 and WWW-Authenticate: Basic, and even the product documentation (help.yesenergy.com) redirects through services.yesenergy.com to a customer login. No public developer portal, no self-serve signup, no machine-readable specification, and no free tier are published. Home market is the United States. There is no consumer energy data mandate that applies to Yes Energy — it is not a utility, retailer, or metering agent, so Green Button, ESPI, and the Consumer Data Right are all out of scope — and while the underlying ISO/RTO market data is publicly available at the source, Yes Energy itself publishes none of it openly.

DataSignals is Yes Energy's REST API for automated access to its North American wholesale power market data — nodal prices, transmission, generation, outages, constraints, weather, and fuels — covering real-time and 15+ years of history, with time-series and object endpoints intended for Excel, Python, R, and system integration. The service host is live and confirmed at https://services.yesenergy.com/PS/rest/, which returns HTTP 401 with WWW-Authenticate: Basic realm="Realm" to anonymous callers; HTTP Basic credentials are issued only to paying subscribers. The endpoint reference and code examples live in the customer knowledge base at help.yesenergy.com, which 302-redirects to the services.yesenergy.com customer login, so no endpoint list, no scopes, and no machine-readable specification could be verified anonymously.

| Dimension | Finding |
|---|---|
| Home market | United States |
| Mandate regime | none |
| Mandate status | not-applicable |
| Data standard | no standard reference found (proprietary REST under /PS/rest/) |
| Consumer data API | No — holds no retail customer usage or billing data |
| Market data open | No — sells wholesale market data that is public at the ISO/RTO source |
| Access gate | customer-account-required (sales-led subscription, then HTTP Basic credentials) |
| Auth model | HTTP Basic (WWW-Authenticate: Basic realm="Realm"); no OIDC discovery document served |
Yes Energy is not a utility, retailer, distribution network operator, or metering agent, so Green Button / ESPI, the Australian Consumer Data Right, and the Ontario Green Button regulation do not apply to it. No compliance claim was made and none needed downgrading — this is a genuine none.
