Agent-ready API

We make an existing HTTP API usable by AI agents: a remote MCP server for its endpoints, x402 pay-per-call in USDC on Base paid straight to your own wallet, and help listing it in MCP and x402 directories. Small API companies, fixed prices, no calls needed.

We run the same stack ourselves: https://freetier-agent-api.pages.dev/mcp (live x402 + MCP server, listed on MCPize, RapidAPI and Zyla). We have no other client references yet.

Prices

Package	Price (USD)	What you get	Delivery
x402 setup	$75 fixed	x402 payments (USDC on Base, to your wallet) on up to 10 existing HTTP routes, with a valid 402 response and Bazaar discovery metadata.	3 business days
Agent-ready	$2,250 fixed	Everything in x402 setup, plus a remote MCP server (Streamable HTTP) exposing up to 8 of your endpoints as tools, with paid tools using x402, plus listing help (see below).	10 business days
Revenue-share option	$0 setup	Same as Agent-ready, but instead of the fixed fee: 10% of the x402 revenue that comes through the MCP server we host, for 12 months, invoiced monthly. Your wallet still receives every payment.	10 business days
Hosting (optional)	$10 / month	We run the MCP/x402 proxy on Cloudflare Workers, watch it and keep it updated. Cancel any time; you get the code.	monthly
Care (optional)	$200 / month	Hosting plus up to 2 hours a month of changes: new tools, price changes, protocol updates.	monthly

How we deliver

You send your API docs (OpenAPI if you have one), a test key, your Base wallet address and the price per call you want.
We build a Cloudflare Worker in front of your API: an x402 middleware that answers unpaid calls with 402 and verifies/settles payments through a public facilitator, and an MCP endpoint whose tools map to your endpoints.
We test it in an MCP client and with an x402 client, then hand over the source code, a README and a test report. You can deploy it in your own Cloudflare account, or we host it.
Listing help: we prepare and, with your approval, submit listings to the MCP Registry, MCP directories and x402 discovery (CDP Bazaar indexes a resource after its first paid call). Approval is up to each directory; we cannot guarantee it.

Not included

New endpoints or changes to your own API.
OAuth sign-in for ChatGPT connectors (quoted separately if needed).
Facilitator or cloud fees on your own accounts (the CDP facilitator is free up to 1,000 payments a month).

Payment terms

Fixed packages: half at start, half on handover. Card or USDC.

How we priced it

About half the median published price of comparable services we found in October 2026: MCP server builds from App369 ($2,500), Toolbridge ($4,500), Fire In Belly ($7,500 pilot), AppMatic Tech (from $8,000) and MCP SI Labs (from $1,900); x402 setup from Stelar Digital ($149); hosting from Serve MCP ($20), MCPHosting.io ($19), osModa ($29), PopMCP ($39) and AIHostBox ($5.99); care plans from MCP SI Labs ($390) and Toolbridge ($400). The 10% revenue share is our own choice.
