One GB-hour of query compute is roughly the cost of scanning 1 GB with moderate complexity. Axiom Cloud, the paid plan, is USD 25/month plus usage and includes 1,000 GB of loading, 100 GB-hours of query and 100 GB of storage. - per-object cap: 1 MB per field, 200 bytes per field name, at most 10,000 events per ingest batch; 256 fields per dataset on Personal | source: [2] | note: The cap is per field, not per event, and applies on every plan. - retention: Maximum data retention 30 days on Personal | days: 30 | source: [2] - egress: All plans include unlimited bandwidth and API access, per the limits page; reading data back is paid in query compute, 10 GB-hours a month on Personal | metered: no | source: [2] - identity: email | detail: The sign-in page creates an account on the first sign-in and e-mails a login link; the pricing page states Personal needs no credit card, and Axiom's Terraform page states that all a free account needs is an e-mail address. A public endpoint also creates a temporary organization with no sign-in: it is deleted with its data after 24 hours unless a person claims it, and claiming it creates an account when none exists. - interface: rest - limits: - volume-quota (binding): 10 GB-hours of query compute a month [2] - volume-quota (binding): 500 GB / month data loading, also the maximum on Personal [2] - volume-quota (binding): 25 GB storage; 3 datasets; 1 user [2] - retention-clamped: 30 days maximum retention [2] - per-object-cap: 1 MB per field; 10,000 events per batch [2] - binding note: 10 GB-hours of query compute is roughly 10 GB scanned a month, against 500 GB that can be loaded, so querying runs out long before ingest. - interface detail: REST API with JSON bodies: ingest and query at the edge deployment's base domain (us-east-1.aws.edge.axiom.co for the US edge, the only edge Personal supports), every other endpoint at https://api.axiom.co, authorised with an API token or a personal access token. api.axiom.co answered 401 to /v2/datasets without a token. OpenTelemetry data is accepted as OTLP over HTTP at https://AXIOM_DOMAIN/v1/traces, /v1/logs and /v1/metrics, where AXIOM_DOMAIN is the base domain of the edge deployment; the metrics endpoint takes Protobuf or JSON. - endpoint: part of interface detail - tooling: curl or any HTTP client with a Bearer token, and OpenTelemetry exporters - composes with: A 30-day searchable store for the logs of free compute services, up to 500 GB loaded a month, with only about 10 GB of it scanned by queries a month. - reliability: An event that would exceed a dataset's field limit is rejected with an error; strings over the field size are replaced with a placeholder. - notes: 500 GB a month of free ingest, against 100 GB on New Relic's free tier and 3 GB on Better Stack's, held back by a 10 GB-hour query budget and 25 GB of storage. - evidence note: Every limit is quoted from a first-party page, and the API host answered 401 without a token. No account was opened; an authenticated ingest and query from a Personal account would move it to measured. - evidence: - [1] 2026-10-30: Personal is permanent and needs no credit card | capture: sha256:61291fd03870a9bbaf215ae35fe5b5a044a9174efe014aa14889ac1e8a48b75c | quote: Permanent.
