The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

No output schema declared.

No examples provided.

accredible_get_design ~50

One badge or certificate design with its settings. GET /v1/designs/{design_id}.

One group in full: name, course name and description, learning outcomes, design ids, language, skills and dates. GET /v1/issuer/groups/{group_id}.

NameTypeReqDescription
group_idintegeryesGroup id (accredible_search_groups lists them).

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

accredible_get_team_member ~69

NameTypeReqDescription

No output schema declared.

No examples provided.

accredible_issue_credential ~490

WRITE: creates ONE credential (badge or certificate) for ONE recipient in an existing group. By default it is created UNPUBLISHED (a draft: no e-mail is sent and no credit is used); publish it later in the Accredible Dashboard. With publish=true the credential is published immediately: Accredible then SENDS AN E-MAIL to the recipient (as configured in the group's e-mail settings) and uses one credential credit of the account; an account without credits keeps it unpublished. A sandbox-mode setting in the Dashboard overrides publish. Not idempotent: calling twice creates two credentials (set credential_id to your own unique id to be able to find it again). No evidence, references, bulk issuing, edits or deletes. POST /v1/credentials.

NameTypeReqDescription
completeboolean–Whether the achievement is complete (default true); false marks it in progress.
credential_idstring–Your own unique id for this credential (license_id); Accredible assigns one if omitted.

descriptionstring–Credential/course description; required only when the group has no course description.

issued_onstring–Issue date YYYY-MM-DD (default today).
meta_dataobject–Key/value strings you attached to the object's meta_data when you created it; matches objects carrying these pairs.
namestring–Credential/course name; required only when the group has no course name.
privateboolean–Make the credential private: visible only to the recipient after signing in to credential.net.
publishboolean–Default false: create an unpublished draft (no e-mail). true: publish now, which e-mails the recipient and uses one credit.
recipient_emailstringyesThe recipient's e-mail address (exactly one recipient).
recipient_idstring–Your own id for the recipient (maps recipients to credentials across e-mail changes).
recipient_namestringyesThe recipient's full name as printed on the credential.

No output schema declared.
