IronBridge API

An API you pay about 10 cents a call to use — no signup, no card, no account. You pay from your own wallet, per call. Prices are in USDC, a digital dollar: 0.10 USDC = about 10 cents.

Live tools — 0.10 USDC per call (about 10¢)

bnkr_llm_chatAsk an LLM a question; the answer comes back with a receipt you can check
gitlawb_chargeA paid provenance check; the fee is split between parties automatically
page_auditAudit a page; keep the receipt. 0.10 USDC on Base.

How it works — pay then prove

  1. Call POST /api/pay/bnkr/<tool>. With no payment you get a 402 carrying the exact price and receiver.
  2. Send the stated USDC (0.10 = about 10 cents) to the receiver from your own wallet on Base.
  3. Call again with header X-IB-Payment-Tx: <your tx hash>. The worker reads the chain, confirms your USDC reached the Safe, then serves the data.

You never share a private key and we never take custody. If the data fetch fails, your payment is released so you can retry with the same tx hash.

Verifiable receipts

Every paid call is sealed into a tamper-evident hash chain. Verify any receipt publicly, no login:

GET /api/receipt/<id>

MCP — live on npm

The same tools are wired as an MCP server that routes through this pay lane, so an agent can pay and call them directly. Package is live on npm.
