Integration guides for AI-agent builders
draconic21 sells SEC EDGAR filings/XBRL, OFAC sanctions screening, US Treasury fiscal data, and a daily agent-economy signal, pay-per-call in USDC on Base via x402. No account, no API key, no subscription — your agent's own wallet pays per call. Every snippet below is real, tested code that runs against the live API.
Pick your stack
Prerequisites
- A wallet on the Base network (chain id 8453) funded with a little USDC — a few dollars covers hundreds of calls at these prices.
- An x402 v2 client library (installed per snippet below) that can sign the "exact" EVM payment scheme (EIP-3009, gasless — no ETH for gas needed on your side).
- Your wallet's private key available to your own process/agent — never share it, never commit it, never paste it into a chat with an AI you don't fully trust with funds.
Routes you can call this way

Each guide above includes its full copy-paste example on this public site. The examples are tested against the live server with payment disabled; they stop at the HTTP 402 challenge until you configure your own wallet. See the public API specification for request and response schemas.
