• heal_malformed_json read-only

  Deterministic JSON syntax repair: normalizes quotes, unclosed brackets, and boolean literals into compliant RFC 8259 JSON structure without data deletion. Use when fixing syntax-broken JSON strings that fail JSON.parse(); for coercing field types and verifying properties on already-parseable JSON objects against a target JSON Schema, use enforce_json_schema_types instead. Read-only edge call (32 KB, 60 RPM): accepts 'malformed_json' (with enum defaults), uses '?demo=true' or L402 (50 sats); HTTP 400 if invalid.

  Parameters:

  • malformed_json (required) — string — Raw broken, truncated, or markdown-wrapped JSON string to repair.
  • repair_mode — string — Bracket-closing and literal-normalization strategy; defaults to 'heuristic_fast' when omitted.

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• enforce_json_schema_types read-only

  Validates a raw LLM output object against a target JSON Schema, automatically coercing mismatched scalar types (e.g. string '42' to integer 42), injecting schema defaults, and pruning undeclared hallucinated fields. Use when enforcing schema compliance and type safety on structured LLM outputs before passing them to typed APIs; for healing unparseable raw JSON text with broken quotes or trailing commas, use heal_malformed_json instead. Read-only edge call (32 KB, 60 RPM): accepts 'raw_output' (with enum defaults), uses '?demo=true' or L402 (75 sats); HTTP 400 if invalid.

  Parameters:

  • raw_output (required) — string — JSON string or object produced by an LLM to validate and coerce.
  • coercion_policy — string — Policy for handling extra undeclared properties; defaults to 'prune_undeclared_and_coerce' when omitted.
