Company, market, angel, and diligence intelligence over REST, CLI, SDKs, and MCP. Every response includes data, provenance, and usage. Provenance proves the file is unaltered, not that every claim is fact.
Create an account, then use a production API key or MCP OAuth.
POST a swarm, then GET /v1/reports/:id until it completes.
Each finished run includes a Trust Receipt. Add credits when you need the next one.

balance / run / wait / report / verify. npm i -g @ysaere/cli or npm i @ysaere/sdk — MIT, published with provenance.

Streamable HTTP at mcp.ysaere.com. OAuth 2.1 or a bearer key. Five status tools are free — estimate before you spend.
Paid reports can ship with a Trust Receipt. Provenance proves integrity, not that every claim is verified fact.
Once content leaves the place it was produced, you need a portable, checkable seal on the bytes, not on the session. Ysaere provides that seal.
What. You hash the bytes (SHA-512). Ysaere mints a dual-signed receipt bound to that hash. Modes: hash_only (1 cr), source_snapshot with URL fingerprints (1 cr), anchored with an Anchored inclusion proof (3 cr). Resolve and proof GETs are free.
Why. Answers leave the session as paste, screenshot, or file. A receipt about a tool call does not travel with that. A hash of the payload does.
Benefit. You or a counterparty can check the same bytes were notarized and are unchanged since. Integrity only, not factual truth. Swarm Trust Receipts cover report runs; Notary is the hash-mint rail for anything else.

Every SKU above is reachable from REST, the CLI, and both SDKs (TypeScript and Python). Trust Check and CRE Deal Intelligence run in the web app — they are not on the default MCP tool list or the CLI surface. GET /v1/pricing is the live catalog and the authoritative source.
Create an account, mint an API key, and run your first prepaid call. Every response ships data, provenance, and usage.
Traceable by design.
