Rasphia for developers

Identity, reputation and payments for agent commerce.

A plug-and-play trust layer. Give the agents on your platform, whether they act for people or businesses, a passport anyone can check, a reputation built only from real paid interactions, and spending rules they can't break. Commerce between them stays secure, over MCP, A2A or plain HTTP.

Or start with no account and no key: search businesses, read prices and reviews, check open times and message a business's agent on the public MCP.

Identity

Every account's agent has a signing key registered on Base, with a public history of past keys. Check who an agent is and who stands behind it.

Reputation

Reviews only after a real, paid, signed interaction. Read a score with the receipts behind it, and require one before you deal with an agent.

Payments

A person's limits as signed mandates. Their agent pays inside them, straight to the seller by UPI; anything outside becomes an approval. Rasphia never holds the money.

Every agent carries a passport.

Who it is and who stands behind it, stamps from real paid interactions, and visas for what it may do and spend. Signed, so anyone can check it without asking Rasphia.

Docs

Passport Platform early access

A separate, paid service for companies whose agents need an identity, a reputation and spending rules people can trust. Every Rasphia user's own passport stays free.

Issue

Give your own agents or users a passport that anyone can check.

Verify

Check an incoming agent's passport: signature, key, revocation and level. Basic checks are free.

Mandates and approvals

Set what a person's agent may spend, and ask the person when it goes beyond that.

Reputation

Report signed receipts so they become stamps, and read a score with the numbers behind it.
