AILANG Parse

A2A Agent Card for agent-to-agent discovery. Returns a hand-crafted Agent Card with AILANG Parse-specific skills, supported formats, and capability descriptions. @raw: return raw JSON (no {result:..., elapsed_ms:N} envelope) for A2A compliance. Switch to @nowrap once available (lighter than @raw). I

Sample files inventory — delegates to the upstream package. Package @route annotations don't auto-register with serve-api, so we provide a local wrapper here.

Tool definitions for Claude, OpenAI, MCP, and A2A agent frameworks. Delegates to the upstream package.

capabilities(() -> string ! {Env}) [pure]

Approve a device authorization request. Called by the browser approval page after user signs in and confirms. Verifies Firebase ID token from Authorization header to ensure the caller is a real authenticated user. Extracts uid from the verified token. Dev mode: ALLOW_SELF_APPROVE=true skips Firebase

Look up a pending device code by user_code and return its provenance. No authentication required — possession of the user_code is the proof. The dashboard /approve.html page calls this BEFORE showing the approve UI so the user can see where the request came from (IP, User-Agent, Referer, age) and de

Poll for device authorization approval. Returns AUTHORIZATION_PENDING if user hasn't approved yet. Returns DEVICE_CODE_EXPIRED if the code has timed out. Returns approved status with API key on success.

Request a device authorization code. Returns device_code, user_code, and verification URL. The agent should display the verification_url to the user.

Parse a document, apply JSON edit deltas, and return the modified blocks as JSON (same format as POST /api/v1/parse with outputFormat=blocks). filepath: uploaded file path (multipart upload). deltas: JSON array of edit operations — see edit_apply.ail for format. Empty array or "" → roun

estimate((string, string) -> string ! {Clock, FS}) [pure]

List all supported document formats for parsing and generation. Returns: parse formats (13), generate formats (9), output formats (blocks/markdown/html/a2ui), and which formats require AI (PDF, images).

Get usage stats for a user's API key. Accepts Firebase JWT or apiKey. Verifies that the requested keyId belongs to the authenticated user.

Request a pre-authenticated GCS upload URL for direct file upload. Business tier only. The returned URL allows the client to PUT file content directly to GCS, bypassing the 32MB Cloud Run request limit. After upload, pass the gcs_ref to POST /api/v1/parse.

Health check for the AILANG Parse API. Returns service status, version, AILANG commit hash, supported format counts, and billing catalog status. `billing_catalog_loaded` is FALSE when the BILLING_PLAN_CATALOG env var is unset or parses to an empty list — in that mode every authenticated request sile

List API keys for a user. Accepts either: - Authorization: Bearer <firebase_id_token> (dashboard path) - {apiKey: "..."} or {args: ["dp_..."]} in body (CLI/SDK path) The resolved userId filters the Firestore query server-side.

View account info, pricing, entitlements, or list keys. Actions: "status" (default) → tier, quota, usage from /me/entitlements "pricing" → public pricing tiers (no auth required) "keys" → list user's API keys with per-key usage "usage" → alias for "keys" (

Start device authorization to get an API key. Returns device_code, user_code, and verification URL. The agent should display the verification URL to the user, who signs in and approves the code. Then call mcpAuthPoll with the device_code. MCP wrappers don't have HTTP request headers, so provenance i

Poll for device authorization completion. Returns "pending" (keep polling every 5s), "approved" (with api_key and tier), or "expired" (start over with mcpAuth).

Convert is not supported on the hosted server (no persistent local filesystem to write the output file to). Use the local stdio SDK (@ailang/parse) for local conversions, where the user has filesystem access.

Estimate cost and latency for parsing a document. Accepts a file path or sample_id. No auth required.

List supported formats, samples, and service capabilities. Pure JSON, no auth required. Delegates to package implementation. Single source of truth lives in pkg/sunholo/ailang_parse/services/mcp/tools.

Parse a document. Accepts a file path or sample_id (e.g. "sample_docx_formatting"). The hosted server requires a valid dp_ API key — get one via mcpAuth. Output formats: blocks (default), markdown, html, a2ui. requestId is reserved for future replay support.

Get the authenticated user's billing entitlements, usage, and plan details. Returns: plan name, monthly request limit, requests used, remaining requests, upgrade/manage URLs. Requires a valid AILANG Parse API key (dp_ prefix).

Parse a document. Requires a valid API key. Validates the key, checks entitlement quotas, logs for replay. filepath: file path OR sample_id (e.g. "sample_docx_formatting" → resolved via /api/v1/samples). outputFormat: "blocks", "markdown", "html", or "a2ui". editable: "true" to emit editable A2UI co

Unstructured API-compatible endpoint (drop-in replacement for Unstructured.io). Returns elements in Unstructured JSON format (Title, NarrativeText, Table, ListItem, etc.). Accepts file upload (multipart/form-data) or JSON body with filepath/sample_id. API key: via unstructured-api-key header (Unstru

pricing(() -> string) [pure]

List recent parse requests for a user. Returns up to 50 entries. Accepts Firebase ID token (dashboard) OR dp_ API key (programmatic). Dashboard sends Authorization: Bearer <firebase_token> with {args: [uid]}. API clients send {args: [apiKey]}. Uses Firestore structured query to filter by user_id ser

Retrieve a stored request/response pair for replay. Requires authentication: Firebase JWT or dp_ API key. The request must belong to the authenticated user (user_id match). Accepts optional outputFormat (blocks/markdown/html/a2ui) to re-render the stored blocks server-side using the ailang_parse pip

Revoke an API key by keyId. Authenticates via either Firebase JWT or apiKey.

Rotate an API key: generate new key, revoke old one, preserve tier + usage.

Anonymous bug report / feature request / docs gap, queued for human review. Default routing: `public-feedback` inbox (general AILANG). Pass `package="vendor/name"` (e.g. "sunholo/auth") to route to that package's `pkg:vendor/name` inbox where its autonomous agent watches. Categories: bug, feature, d
