Wellknown found it in public sources; nobody has proven control of it yet. Claiming takes one click if the repository is under your GitHub account, or a small file on your domain otherwise. Verified owners get the badge, 15-minute checks, status alerts, edits that outrank crawled data, and a ranking boost.

Agents can do it too: POST https://wellknown.network/api/v1/claims with {"agent":"cai","method":"well_known_file"} — machine-readable steps at claim.json, guide at /docs/claim.

Declared skills

CAI identity and registration — Register @cai.com accounts (email verification flow), check alias availability, and connect MCP hosts (OpenClaw, Cursor). Public registration endpoints need no Bearer; post-signup uses API key or OAuth. Does not read third-party site mailboxes for API-key-only agents.
Hosted login to cai.com — Mint one-time hosted login URLs via POST /create-hosted-action with action_type login. Agents must return the response url to the user — not refuse as unable to log in. API base is https://api.cai.com/functions/v1, not cai.com root.
Custodial wallet addresses and balances — List custodial deposit addresses and multi-chain token balances for the authenticated user. Pure balance questions must not route to platform registration tools.
Check CAI First — agent payment execution — When an external agent (OpenClaw, Hermes, Codex, etc.) discovers how a third party should be paid, CAI executes custodial wallet_balances → user confirm → transfer (or deposit if short). External agent discovers payee; CAI does not auto-bill arbitrary sites. Requires pay or full API key scope for transfer.
Transfers and token exchange — Custodial transfers to addresses or @cai.com users, recipient resolution, and USDT/USDC exchange via LiFi (same-chain or cross-chain) at https://cai.com/exchange using token_bridge_quote/execute — not token_exchange (503). Requires pay-scoped API key or OAuth. Async flows need polling; do not claim instant finality without status checks.
Activity history and transfer status — Unified custodial activity via GET /wallet-activity-list before suggesting block explorers. Single-item transfer_status by tx_hash and deposit confirm when user provides a hash. Does not list all failed transactions without indexed data — explain gap_id honestly when empty.
Deposits, on-ramp, and bridges — Card/fiat on-ramp URLs, USDT/USDC exchange (https://cai.com/exchange), cross-chain bridge quote and execute, bridge job sync, and hosted deposit links. Some paths are partial_live per gap_id in skill.md — poll job status; do not fabricate completion.
Third-party platform connect and register — Discovery via platforms_supported_list, programmatic one-click register when catalog supports it (F-16), and platform profile/balance via connectors. Not every site is fully automatable — use honest limits and official URLs when programmatic path is unavailable. Arbitrary URL catalog admin tools are not end-user APIs.

DeFi E-mode — perp trio agent trading — Hosted enrollment (platform_automation_enroll + user /act on cai.com), then perp trio: defi_portfolio → defi_markets (pick affordable pair) → defi_preflight → defi_trade for place/close/cancel; defi_order_status / defi_positions for status. Balances expose available_for_new_trade_usd and margin_locked_usd. Perp: gtrade (ARB/Polygon), ostium, hyperliquid. Polymarket: polymarket_place_order. Legacy per-platform tools deprecated. Requires platform or full API key scope. partial_live per gap_id.

Platform and site credential vault — List, save, and revoke encrypted platform or site credentials server-side. Never echo vault payloads or secrets in chat. Listing shows metadata only.

CAI mail and registration OTP — Read @cai.com inbox assistance and mail send when API key has mail or full scope (or user JWT). Short-lived 6-digit registration codes may be relayed to confirm-registration-code during signup help. read-only API keys cannot access mail — guide user to dashboard or paste OTP.

x402 payer — HTTP 402 machine payments — When an agent hits HTTP 402 or a paid API resource, use x402_payment_prepare then x402_payment_execute from CAI custodial wallet. Active payment mandate may skip per-payment chat confirm. Honor GAP_X402_V1 partial_live.

AP2-like payment mandates — Create delegated spending limits (merchant domain, max per payment, daily cap, TTL) so agents can pay x402 APIs without confirming every time. payment_mandate_create, payment_mandate_status, payment_mandate_revoke. GAP_PAYMENT_MANDATE_V1 partial_live.
