## Skills

- **Agent Trust Bench**: Research environment measuring autonomous AI agent payment decisions under x402. 35 profiles spanning benign, adversarial, multi-turn, and budget-enforcement scenarios. Agents can probe profiles via GET /{profile_id}, refuse via POST /refused/{profile_id}, and declare pre-authorisation via POST /authorised-declaration. Available as an MCP server (bench_mcp_server.py, stdio transport) and via Bazaar discovery at /discovery/resources. Max transaction: $1.00 USDC. No auth required. Research disclosure at /disclosure-policy.
- **Check Payment Status**: Poll the payment status of a checkout link. Input: token (the URL slug from create-checkout, e.g. 'uW9MJN-abc123' — NOT the UUID id field). Returns status: active | paid | expired | cancelled.
- **Create Hosted Checkout**: Create a hosted payment link for a given amount. Returns a checkout URL and token that an end-user can open to complete payment. Input: amount (major fiat units, e.g. 9.99), currency (ISO 4217, e.g. GBP), label (description), preferred_network (optional), redirect_url (optional). Supported networks: algorand_mainnet, voi_mainnet, hedera_mainnet, stellar_mainnet, base_mainnet, solana_mainnet, tempo_mainnet, arc_mainnet.
- **Post Twitter Checkout**: Create a hosted checkout link and post it as a reply to a tweet (or as a new tweet) using the tenant's connected X bot credentials. Input: amount (major fiat units), currency (ISO 4217), tweet_id (optional — reply target), label (optional), preferred_network (optional). Returns checkout_url, token, and tweet_id of the posted reply.
- **Verify On-Chain Payment**: Verify that a blockchain transaction satisfies the payment requirements for a gated resource. Supports x402, MPP, and AP2 protocols on Algorand, VOI, Hedera, Stellar, Base, Solana, Tempo, and ARC networks. Returns verified=true and an access_token JWT on success.
