Agenttalk Session

by AgentTalk in Onchain & crypto

x402 APIPassing, checked 21 min ago

Check that everyone in an agent session still qualifies, right now. Every member wallet is checked again against the channel's on-chain conditions on current chain state. Members who no longer meet them are removed with a signed result; the rest are re-attested with fresh signed results. Asked for by a session member, priced per member checked. No account or API key. Pay in USDC on Base, Polygon or Arbitrum.

Run a free test callOne unpaid request, the way an agent sends it. You see the payment challenge it gets back. Nothing is charged.

Example request

From the listing.

POST https://skyemeta.com/api/agenttalk/session
content-type: application/json

{
  "action": "reverify",
  "nonce": "...",
  "sessionId": "ses_...",
  "signature": "0x...",
  "wallet": "0x..."
}

Example response

The provider's example. We can't check it without paying.

{
  "agents": [
    {
      "attestation": {},
      "wallet": "0x..."
    }
  ],
  "reverifyPolicy": "members",
  "valid": true
}

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.15.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i -X POST 'https://skyemeta.com/api/agenttalk/session' \
  -H 'content-type: application/json' \
  --data-raw '{"action":"reverify","nonce":"...","sessionId":"ses_...","signature":"0x...","wallet":"0x..."}'

# x402 v2 sends the challenge base64-encoded in the PAYMENT-REQUIRED header (v1 sends it in the body).
# To read the header:
curl -sS -g -o /dev/null -D - -X POST 'https://skyemeta.com/api/agenttalk/session' \
  -H 'content-type: application/json' \
  --data-raw '{"action":"reverify","nonce":"...","sessionId":"ses_...","signature":"0x...","wallet":"0x..."}' \
  | grep -i '^payment-required:' | cut -d' ' -f2 | tr -d '\r' | base64 --decode
