How you sign in

Claude users: sign in with Ysaere during Connect. No extra client secret. Authorization server: https://api.ysaere.com. Client ID: claude.ai.

API key (Cursor and Inspector)

Create a production key in Developer, MCP Server, then send Authorization: Bearer ysa_prod_…. That spends prepaid credits. Sandbox keys are rejected here.

Pay from a wallet (no Ysaere account)

Short tools accept USDC. Send Accept-Payment: x402, settle the price challenge, then retry. Classify is $0.20. Know Your Business is $0.10. Quick Brief is $2. Sourced Brief is $0.30. Full research reports still need an account.

Three steps

  1. Connect to https://mcp.ysaere.com/mcp.
  2. Try it: company_snapshot is free. Classify and Know Your Business can settle in USDC or credits.
  3. Go deeper: create an account at app.ysaere.com, then run Angel or Company Intelligence and wait for the report.

When a report finishes

In Claude, poll with wait_for_report. Backends can also register POST /v1/webhooks for report.completed. See Builders, Examples.

Hash this sentence with SHA-512, then call notary_hash in hash_only mode. Tell me what the receipt proves (integrity, not that the sentence is true).

What you can run

Start free. Pay for a short tool. Sign in for a full report. A receipt proves the file was not altered. It does not prove every claim is fact.
