What it does
Ausca is a set of paid services for agents with no account and no API keys. The agent sends a request, receives an x402 payment requirement, pays in USDC on Base within the ceiling you set and reads the result with proof of settlement. Every completed call carries a signed receipt with a public verification page that stores only a hash. There are six services. Document OCR returns normalized text with line confidence, Document Analysis extracts forms, tables, signatures and layout, and Media Transcription transcribes audio and video. Browser Session opens a remote browser with CDP access, Agent Inbox gives a receive-only mailbox, and Inbox Extension extends an active inbox at the same address. Prices, schemas and the catalog are public at ausca.com/catalog.json. The local MCP server starts with `npx -y ausca mcp` and holds your wallet: the payment is signed on your side and stays within AUSCA_MAX_PAYMENT_USD. The remote server at ausca.com/mcp serves discovery, preparation and state reads. For documents and media you first upload a file with `npx ausca commit`, and the service takes an immutable commitment instead of raw bytes. Five skills install from the repository: agent-inbox, browser-session, document-analysis, document-ocr and media-transcription.
Who it is for. Developers of autonomous agents that need OCR, transcription, a browser or mail on demand without opening accounts or subscriptions.
Good fit when
- An agent receives a scanned contract and must extract text and tables for a one-time fee
- You need a meeting recording transcribed with no service subscription
- For a signup check an agent needs a temporary mailbox for an hour or a day
- An agent needs a remote browser for ten minutes over CDP
- Agent spending on services must hit a hard cap in dollars
Not a fit when
- You need payment by card or in rubles: settlement is only in USDC on Base
- You have no wallet with USDC: paid calls are unavailable without one
- You need to send mail: Agent Inbox only receives
- Document data must not leave for an external service
Example request

Environment variables
AUSCA_PRIVATE_KEYrequired, secret- Private key of the wallet that pays USDC on Base.
AUSCA_MAX_PAYMENT_USDrequired- Hard per-call payment ceiling in dollars.
Limitations
Payment is USDC on Base only, so a wallet and a private key in AUSCA_PRIVATE_KEY are required. The key lives in the client environment, so keep a small amount on it.
The AUSCA_MAX_PAYMENT_USD ceiling and the idempotency key are set explicitly. A retry with a new key counts as a new purchase, so keep the old key when the outcome is uncertain.
Results contain private access capabilities, so do not publish them raw. The services' own code is not in the repository, only the client side.
The command `npx -y skills add auscahq/ausca --skill '*'` installs all five skills. Access from Russia was not checked for this card.
How to disable. Remove the ausca entry from the MCP client config and delete the private key from the environment. Skills are removed with `npx skills remove` or by deleting their folders.
FAQ
Which services does Ausca sell?
Document OCR at $0.25 per document, Document Analysis from $0.30 to $0.75, Media Transcription from $0.40 to $1.30, Browser Session from $0.05 for ten minutes, Agent Inbox from $0.05 an hour. The live catalog at ausca.com/catalog.json remains the main source of prices.
Do I need an account or API key?
No. Services follow the x402 protocol: a request gets a payment requirement, and the client pays USDC within your ceiling and retries. Only a wallet with a key is needed.
How do I install the Ausca skills?
Run `npx -y skills add auscahq/ausca --skill agent-inbox`, replacing agent-inbox with browser-session, document-analysis, document-ocr or media-transcription. The `--skill '*'` flag installs all five at once.
How do the remote and local servers differ?
The remote ausca.com/mcp serves discovery, preparation and state reads, and the payment is always signed on your side. For paying you therefore need the local `npx -y ausca mcp` with a wallet.
What is an Ausca receipt?
A signed confirmation of a completed call. Every receipt has a public verification page that holds only a hash, so document content is not exposed there.
