Measured tools (14)

• axis_list_capabilities read-only

  List all AXIS Foundry capabilities (input formats, export platforms, validation rules). [Free — no payment required.]

  Parameters:

  • kind — string — Filter by capability kind

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

• axis_validate read-only

  Validate an avatar mesh file. Returns pass/warn/fail counts and detailed rule results. [Paid: $0.25 USDC via x402 for unauthenticated calls on the hosted /mcp endpoint; settled only on a successful (non-error) result.]

  Parameters:

  • file_path (required) — string — Path to mesh file (.glb, .obj, .stl, etc.)
  • profile — string — Validation strictness profile
  • platform — string — Target platform for platform-specific validation

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

• axis_inspect read-only

  Inspect an avatar's contract state and provenance chain (stage, bone/vertex counts, provenance step count, chain_valid + any broken links). Does not return a quality grade — use axis_validate for pass/warn/fail rule results. [Paid: $0.10 USDC via x402 for unauthenticated calls on the hosted /mcp endpoint; settled only on a successful (non-error) result.]

  Parameters:

  • file_path (required) — string — Path to mesh file

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

• axis_compare read-only

  Compare two avatar contracts. Returns similarity score and section-level diffs. [Paid: $0.10 USDC via x402 for unauthenticated calls on the hosted /mcp endpoint; settled only on a successful (non-error) result.]

  Parameters:

  • file_a (required) — string — Path to first mesh file
  • file_b (required) — string — Path to second mesh file
  • sections — array — Limit comparison to specific contract sections

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

• axis_process read-only

  Run the full AXIS avatar pipeline (classify → normalize → rig → skin → validate). Returns contract summary. [Paid: $1.50 USDC via x402 for unauthenticated calls on the hosted /mcp endpoint; settled only on a successful (non-error) result.]

  Parameters:

  • file_path (required) — string — Path to mesh file
  • export — boolean — Also export to the target platform
  • platform — string — Target platform

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

• post_process_mesh read-only

  Post-process a RAW generated mesh (normalize → mesh-repair → rig/skin → validate → export) and return the finished, validated GLB as base64. The inline counterpart of axis_process (which needs a server file path) — the generation post-process step, callable by an LLM/agent that holds the mesh bytes (e.g. fresh TRELLIS output) or a URL to them. Provide the mesh EXACTLY one of two ways: inline as base64 (glb_base64) or as an HTTPS URL (mesh_url) — the URL's host must be on this server's operator-configured allowlist (off by default; an unconfigured allowlist refuses every mesh_url call, it is never open to an arbitrary host). Providing both or neither is a real input error. [Paid: $1.50 USDC via x402 for unauthenticated calls on the hosted /mcp endpoint; settled only on a successful (non-error) result.]

  Parameters:

  • mesh_url — string — HTTPS URL to fetch the raw GLB from instead of inline base64 (e.g. a presigned storage URL) — the host must be on this server's configured allowlist (off by default). Provide exactly one of glb_base64 or mesh_url.
  • platform — string — Target engine platform (adds export validation)
  • asset_kind — string — Asset kind (skinning auto-on for avatar only)
  • glb_base64 — string — Base64-encoded raw binary GLB to post-process. Provide exactly one of glb_base64 or mesh_url.
  • polygon_tier — string — Decimation tier for the output mesh
  • run_skinning — boolean — Override skinning (default: avatars only)

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

• axis_export read-only

  Export an avatar to a target engine platform with validation and HMAC-signed manifest. [Paid: $0.50 USDC via x402 for unauthenticated calls on the hosted /mcp endpoint; settled only on a successful (non-error) result.]

  Parameters:

  • file_path (required) — string — Path to mesh file
  • platform (required) — string — Target platform

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

• axis_manifest_verify read-only

  Verify an export manifest's integrity and optionally check content hash. [Paid: $0.10 USDC via x402 for unauthenticated calls on the hosted /mcp endpoint; settled only on a successful (non-error) result.]

• generate_avatar_from_text

  PAID (x402, 5 USDC): generate a production 3D avatar from a text prompt — xAI concept image → TRELLIS.2 GPU mesh → full canonical post-process (repair/validate/export). Payment settles ONLY when generation completes; a failed generation is never charged. Returns a job_id — poll with the free get_generation_status tool (typical runtime 5-15 minutes). Pass idempotency_key when a retry is possible (timeout/5xx) — replaying the same key returns the original job_id instead of a second GPU job/charge. [Paid: $5.00 USDC via x402 for unauthenticated calls on the hosted /mcp endpoint; DEFERRED settlement — charged only when the generation job completes, a failed job is never charged. Poll get_generation_status (free).]

  Parameters:

  • prompt (required) — string — What to generate (subject description)
  • platform — string — Target engine (adds rigging + engine export)
  • asset_kind — string — Asset taxonomy
  • polygon_tier — string — Quality tier (defaults to the platform's configured tier)
  • texture_size — number — Texture bake size in px (defaults per platform, else 2048)
  • idempotency_key — string — Optional caller-chosen dedup key (<=200 chars, [A-Za-z0-9_.:-]). Replaying the same key (per payer) returns the original job_id — no new GPU job, no new charge. Use on any retry after a timeout/5xx.

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

• generate_avatar_from_image

  PAID (x402, 6 USDC): generate a production 3D avatar from a reference photo (base64) — xAI A-pose normalize → TRELLIS.2 GPU mesh → full canonical post-process. Payment settles ONLY when generation completes; a failed generation is never charged. Returns a job_id — poll with the free get_generation_status tool (typical runtime 5-15 minutes). Pass idempotency_key when a retry is possible (timeout/5xx) — replaying the same key returns the original job_id instead of a second GPU job/charge. [Paid: $6.00 USDC via x402 for unauthenticated calls on the hosted /mcp endpoint; DEFERRED settlement — charged only when the generation job completes, a failed job is never charged. Poll get_generation_status (free).]

  Parameters:

  • image_b64 (required) — string — Base64-encoded reference image (PNG/JPEG)
  • prompt — string — Optional style/subject hint alongside the image
  • platform — string — Target engine (adds rigging + engine export)
  • asset_kind — string — Asset taxonomy
  • polygon_tier — string — Quality tier (defaults to the platform's configured tier)
  • texture_size — number — Texture bake size in px (defaults per platform, else 2048)
  • idempotency_key — string — Optional caller-chosen dedup key (<=200 chars, [A-Za-z0-9_.:-]). Replaying the same key (per payer) returns the original job_id — no new GPU job, no new charge. Use on any retry after a timeout/5xx.

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

• get_generation_status read-only

  FREE: poll a generation job submitted by the paid generate tools. Returns status/progress; once complete AND the deferred payment has settled, returns the download URLs. A failed generation reports charged=false. Look up by job_id, or by idempotency_key + payer if the job_id was lost. [Free — no payment required.]

  Parameters:

  • payer — string — x402 payer address the original generate call used — required when looking up by idempotency_key (scopes the key to its owner).
  • job_id — string — Job id returned by a generate tool
  • idempotency_key — string — Alternate lookup key: the idempotency_key passed to the original generate call. Requires payer.
