What it does

Pre-interaction due diligence for a Solana program ID: loader, whether the code is upgradeable, the upgrade authority and its kind — `pda` (off the ed25519 curve: a program-derived address controlled by a program such as a multisig vault or governance), `key` (on-curve: a regular key address, one signer unless held in custody/MPC we can't see) or `none` (immutable) — plus the authority account's owner program, last deploy slot and time, and OtterSec verified-build status (repo, commit, hash match). Live on-chain + verify.osec.io data at request time; facts only, no score. $0.005 per call.

Use with an agent

Discover. Agents find this listing with GET https://bazaar.saylorinnovations.com/discovery/search?query=…, the MCP tool search_resources, or /discovery/resources.
Inspect. Fetch /resources/64152.json for the price and payment options.
Pay. Call GET https://x402.45-63-29-234.sslip.io/v1/solana/program-trust. The provider answers 402 with its payment requirements. An x402 client signs one of the options below and retries with PAYMENT-SIGNATURE.
Execute. The provider returns 200 with the data. Agent Bazaar is not in the request path and never sees your payment.

For humans

You don't need an account or an API key; you need a wallet holding a small amount of USDC on Base, and an x402-capable client (see the examples below). Call the endpoint unpaid first to see exactly what it asks for.
