Tools

Token cost is the o200k count of the tools list JSON, including schemas, before any tool is called. Showing 12 of 17.

• basis_theory_list_tokens

  List vault tokens as METADATA — id, type, container, fingerprint, metadata and timestamps. Does not return the underlying card number or PII. Basis Theory: GET /v2/tokens.

• basis_theory_search_tokens

  Search tokens with Basis Theory's query syntax over metadata, e.g. metadata.customer_id:"cus_1". Returns metadata only. Read-only despite being a POST — the query goes in the body. Basis Theory: POST

• basis_theory_get_token

  Fetch a single token by id. Returns metadata, container, fingerprint and timestamps. WARNING: if the configured API key carries a reveal permission, the response also contains the token's plaintext da

• basis_theory_list_applications

  List the applications (API-key holders) in the tenant, with their types and permissions. Basis Theory: GET /applications.

• basis_theory_get_application

  Fetch a single application with its type and permission list. Basis Theory: GET /applications/{id}.

• basis_theory_whoami

  Return the application the configured BT-API-KEY belongs to — the fastest way to check which permissions this server actually has. Basis Theory: GET /applications/key.

• basis_theory_list_logs

  List audit-log entries — who did what to which entity and when. The tool for answering 'who touched this token?'. Basis Theory: GET /logs.

• basis_theory_list_log_entity_types

  List the entity types the audit log records — the valid values for entity_type. Basis Theory: GET /logs/entity-types.

• basis_theory_list_proxies

  List the proxies that forward requests to third parties, detokenizing in flight. Basis Theory: GET /proxies.

• basis_theory_get_proxy

  Fetch a single proxy with its destination URL and transform configuration. Basis Theory: GET /proxies/{id}.

• basis_theory_list_reactors

  List reactors — the serverless functions that run against detokenized data inside the vault. Basis Theory: GET /reactors.

• basis_theory_get_reactor

  Fetch a single reactor with its configuration. Basis Theory: GET /reactors/{id}.
