.well-known Generator

Fill in your agent's basics to generate two standard discovery files: the A2A agent-card.json and the IETF Web Bot Auth signature directory. Everything is generated in your browser with zero upload; the output passes the corresponding checks of this site's Agent Identity Checkup.

Ed25519 public key (JWK, for the signature directory)

No key yet? Two commands

Run these on your own machine. The private key stays local; paste only the printed public JWK above — this tool is purely client-side with zero network calls, nothing is ever uploaded.

# 1) generate an Ed25519 private key (keep it yourself, never upload)
openssl genpkey -algorithm ed25519 -out bot-private.pem
# 2) export the public key
openssl pkey -in bot-private.pem -pubout -out bot-public.pem
# 3) print the public JWK (paste it into the box above)
node -e "const{createPublicKey}=require('crypto');console.log(JSON.stringify(createPublicKey(require('fs').readFileSync('bot-public.pem')).export({format:'jwk'})))"

# one command: keypair generated, private key saved to PEM, public JWK printed
node -e "const{generateKeyPairSync}=require('crypto');const{publicKey,privateKey}=generateKeyPairSync('ed25519');require('fs').writeFileSync('bot-private.pem',privateKey.export({type:'pkcs8',format:'pem'}));console.log(JSON.stringify(publicKey.export({format:'jwk'})))"

agent-card.json

Deploy at (site root): /.well-known/agent-card.json

The checkup requires non-empty name and url — fill in the agent name and site URL first.

Deploy at (site root, no file extension): /.well-known/http-message-signatures-directory

Paste an Ed25519 public JWK to generate the signature directory here

Generated? Run the checkup

Deploy both files under /.well-known/ at your site root, then verify with the checkup — the AgentCard and Web Bot Auth items should score full points.
