Common questions

Is US Economic, SEC EDGAR & On-Chain Data (x402) safe?

It passed 0 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.2.0) reached the registry 3 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

US Economic, SEC EDGAR & On-Chain Data — a pay-per-call MCP server

21 data tools that AI agents discover and pay for per call, settled in USDC on Base via the x402 payment protocol. No account, no API key, no subscription.

Live: https://x402.agentfund.net · Agent guide · Verification ledger · Settlements

Endpoint	Purpose
`POST /mcp`	MCP over streamable-HTTP (stateless)
`POST /x402/`	One HTTP route per tool; arguments as a plain JSON body
`GET /openapi.json`	OpenAPI 3.1 discovery document with `x-payment-info` per route
`GET /SKILL.md`	Agent-facing usage guide
`GET /VERIFICATION.md`	How each tool was verified, and the upstream traps found
`GET /monitor`	Live on-chain settlement dashboard
`GET /health`	Liveness and configuration mode

The tools

US macro — treasury_yield_curve, bls_cpi, macro_pce, macro_jobs, macro_gdp, macro_retail_sales, macro_housing, macro_energy, macro_release_calendar

SEC EDGAR — edgar_filings_feed, edgar_financials, edgar_insider_transactions, edgar_13f_holdings, edgar_full_text_search

On-chain EVM — onchain_token_balances, onchain_portfolio, onchain_cross_chain_balances, onchain_oracle_price, onchain_gas

Pure compute — structured_json_repair, tabular_to_json

Prices run $0.001–$0.03 per call.

Why these sources

Every tool wraps free public-domain US government data (Treasury, BLS, BEA, Census, EIA, SEC EDGAR) or a direct on-chain read via public RPC. There is no upstream vendor licence, so nothing here can be revoked or repriced by a third party, and the cost of goods is zero.

The trade-off is inherited from the publishers: government statistics are lagged and revised, 13F is quarterly and stale by design, and none of this is market data. Those limits are stated plainly in SKILL.md rather than buried.

Correctness

Every tool was checked against live upstream data before shipping — not only against unit tests, because a test written from the same wrong assumption as the code passes happily.

That caught six real defects, including 13F values being 1000× too large by following SEC's *own* documentation, and Census silently returning five regional rows where a national figure was expected. Each is documented with the evidence that exposed it, and locked in by a regression test: [VERIFICATION.md](VERIFICATION.md).

A failed call is never billed. The MCP SDK turns a thrown tool error into an HTTP 200 carrying isError: true; the payment gate inspects the result and returns errors unsettled rather than charging for a result the caller never received.

Architecture

x402 v2 (@x402/core, @x402/evm) with the Coinbase CDP facilitator on Base mainnet.
MCP on Workers via @hono/mcp StreamableHTTPTransport (the SDK's own transport is Node-http-based). Stateless JSON.
Two entry points, one payment path. /mcp and /x402/ both run through PaymentGate.chargeAndRun, so money-safety rules cannot drift between them.
Per-tool HTTP routes exist for discovery. The x402 Bazaar indexes plain HTTP resources only — every catalog entry is type: "http" — so an MCP endpoint alone can never be listed.
Discovery needs no secrets. initialize, tools/list and ping are answered without payment configuration, so the server introspects cleanly on a fresh clone or in a CI sandbox.
Validation uses `@cfworker/json-schema`, not Ajv — Ajv compiles via Function, which Workers forbid, and the schema is a runtime input so it cannot be precompiled.
No private keys. The server holds only a public payout address; config.ts refuses private-key- or seed-shaped input.

Adding a tool is a one-file change plus a line in src/tools/index.ts.

Development

npm install

npm test # 174 tests npm run typecheck npm run dev # wrangler dev npm run dev:node # tsx watch src/node.ts

Copy .dev.vars.example to .dev.vars for local configuration. Only the public payout address is ever needed — never a private key or seed phrase.

Docs are mirrored into the bundle (Workers have no filesystem); run npm run gen:docs after editing SKILL.md or VERIFICATION.md, or test/docs.test.ts will fail on the drift.

Deployment

Production runs on Cloudflare Workers. Secrets are set with wrangler secret put, never in wrangler.toml:

npx wrangler deploy --env production

A Dockerfile is included for self-hosting the Node entrypoint; it needs no secrets, so the container starts and passes introspection out of the box. See OPERATOR_CHECKLIST.md for the full runbook.

Buyer-side test clients

PAYER_PRIVATE_KEY=0x… node scripts/pay-test.mjs      # pay via /mcp

PAYER_PRIVATE_KEY=0x… node scripts/pay-http.mjs # pay via /x402/ node scripts/index-all.mjs # dry run: Bazaar index status

Payment is gasless for the payer (the facilitator submits the transaction), so a test wallet needs USDC and no ETH. index-all.mjs skips already-indexed routes and refuses to spend without --yes.
