HTTPie

HTTPie is a user-friendly command-line and web-based HTTP client designed for testing, debugging, and interacting with APIs and HTTP services. It provides expressive syntax that mirrors actual HTTP requests, formatted and syntax-highlighted output, native JSON support, file uploads, form submissions, persistent sessions, multiple authentication schemes (basic, digest, bearer, .netrc, and an extensible plugin system covering OAuth, AWS, NTLM, and more), download mode similar to wget, HTTPS and proxy support, and cross-platform installation across Linux, macOS, Windows, and FreeBSD. The companion HTTPie web app and Desktop client layer a graphical interface over the same request and response model that the CLI exposes.

HTTPie publishes 2 APIs on the APIs.io network: App API and Hello API. Tagged areas include API Client, API Testing, CLI, Clients, and Command Line.

The HTTPie catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.

HTTPie’s developer surface includes documentation, signup flow, engineering blog, pricing, and 6 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.
Create-or-Update Ergonomics does not apply to this provider. The published contracts declare no write operations, and a read-only API cannot create-or-update. The facet is excluded from this provider's denominator entirely — not scored zero. A reference or data API is not deficient for being unable to upsert.
The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/httpie: open an issue to ask a question, or submit a pull request to add artifacts.

What adopting HTTPie moves on the Kin Score 1

HTTPie is an area vendor: providers adopt it to run part of their developer surface. This is the Kin Score checks its features can move for a provider that adopts it, what each one really earns, and what it earns nothing for.

api collectionscapability map3 features checked 2026-09-25 · rubric v0.22.0

HTTPie makes calling an API pleasant; it does not publish anything a provider’s score reads. Its collections export to HTTPie’s own JSON format (with a public schema), not to Postman or OpenAPI, so postman_present and contract_present are out of reach, and the HTTPie CLI is HTTPie’s, not the provider’s. The one conditional route is a published export used as an example corpus. A provider adopting HTTPie should expect no score movement.

Contract Quality4.0 of 211 pts
CheckEarnsThrough
Published example corpusconditional
Contract QualityOnly if the provider publishes an exported collection that covers real calls with real payloads and declares it as Examples. The export is a request set, not a Postman collection or a contract.		 4.0 of 4 Versioned JSON export
Across 8977 providers that publish a contract, adopting HTTPie would move 0. Median lift: composite +0.0 (90th percentile +0.0), agent readiness +0.0 (+0.0). Conditional rows excluded.
What HTTPie ships that earns nothing (2)
  • Versioned JSON export — HTTPie exports its own JSON format; the check reads Postman-typed pointers only.
  • HTTPie CLI — The HTTPie CLI is a general HTTP client, not a command-line interface the provider publishes for its API.

A model, not a score. Adopting this vendor changes a provider's Kin Score only when the provider publishes the resulting artifacts on its own surface; nothing here writes a score, and no sponsorship or partnership can. The rating is not for sale → · Full vendor facets artifact
