Memfault is a device observability and reliability platform for connected products built on MCUs, embedded Linux, and Android. The Memfault Cloud ingests device data (coredumps, logs, metrics, reboots) and provides issue grouping, alerting, charting, fleet analytics, and over-the-air firmware updates. The Memfault REST API exposes organizations, projects, devices, software, releases, deployments, issues, alerts, metrics, and chunk ingestion endpoints.
Memfault publishes 15 API contracts indexed on the APIs.io network, including Auth API, Chunks Ingestion API, Cohorts API, and 12 more. Tagged areas include Alerts, Android, Crash Reporting, Device Management, and Embedded.
The Memfault catalog on APIs.io includes 1 Spectral governance ruleset.
Memfault’s developer surface includes authentication, documentation, CLI, GitHub presence, engineering blog, pricing, support, and 15 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 applies to this provider. This API accepts writes, so it
carries 10 points of the composite. It is scored from the published contracts
themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already
holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in
front of it, and the first time that check is skipped a duplicate record is created.
Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet,
not penalised by it.
The six quality facets above are damped to 75 points between them,
because the conditional facet above carries the other
25. That is why each facet's contribution is shown against a damped
maximum: raising a quality facet moves the composite by 75% of its nominal
weight, not 100%. The full arithmetic is at apis.io/rating/.

Agent readiness — checks not met, largest first (exact, from this profile):
Idempotency+9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented) Ask about this →
Stable Error Semantics+8 pts — OpenAPI $refs a shared error schema across 4xx/5xx responses (verified), else common[].type includes ErrorCatalog / ErrorCodes / DeclineCodes Ask about this →
Delegated User Identity+6 pts — a served discovery document listing authorization_code in grant_types_supported (served), else an oauth2 authorizationCode flow or openIdConnect declared in an OpenAPI (documented) Ask about this →

Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
