Providers reference
Every Provider in boast’s default registry, which Category it serves, whether it’s
enabled by default, and what environment variable (if any) it needs a key in. This page
is generated from boast providers — the same command you can run yourself to check
what’s obtainable before running about.

altmetric Attention yes required: ALTMETRIC_KEY (not set)
An optional key raises a rate limit or unlocks extra Metrics but isn’t required; a required key means that Provider reports every Metric as not-applicable until it’s set (never as zero — see ADR-0002).
OpenAlex and Europe PMC also accept GitHub repository identities. For a repo they add an
independent mentions Metric under Attention, based on each service’s indexed full-text
search. These are coverage-limited estimates, not formal citation counts or verified
literal URL occurrences; the values are shown side by side and are never summed.
