We build crypto agents and pay-per-call data APIs
Token risk checks, wallet and whale analytics, compliance screens and market data that AI agents can find and pay for per call in USDC. We have built and run this stack ourselves, and we can build yours.

Proof: this site
The Trading Signals Toolkit you are on is our own build, live in production:
- 21 MCP tools on a hosted remote MCP server (/mcp), also published as an npm package (x402-trading-signals-mcp) and listed on the official MCP Registry.
- x402 v2 payments in USDC on Base and Solana, through the Coinbase CDP and PayAI facilitators, with discovery files (/.well-known/x402, OpenAPI, llms.txt).
- Stripe MPP (machine payments in USDC on Tempo) on the same routes, plus Stripe subscriptions and a free API-key tier.
- Agent framework plugin: an ElizaOS plugin on npm (@gdietsch/plugin-trading-signals) with token verdict, pre-trade and whale-flow actions.
- Open source: x402 setup kit and copy-paste examples for curl, JavaScript, Python, MCP clients, LangChain and the OpenAI Agents SDK.
Three ways to work with us
x402 Setup Review

- 402 responses, facilitators, wallets, discovery files and optional MPP
- Written punch list within 2 business days
- One round of follow-up questions
Full Setup
- We add x402 v2 to your existing API: USDC on Base and Solana
- Coinbase CDP plus PayAI facilitator fallback; Stripe MPP if your account is ready
- llms.txt, OpenAPI, /.well-known/x402, x402scan and PayAI listings
- Optional hosted MCP endpoint for your routes
- $750 for one API; up to $1,500 for several services or larger changes, quoted before we start
Custom agent or data API
- A new pay-per-call data API or crypto agent built for you
- On-chain and public data sources, scoring logic, caching and tests
- x402 / MPP payments, MCP server and agent plugin if you want them
- Deployed on your hosting, in your repo, under your wallets
- Fixed quote after a short scope call; no payment until you accept it
Example builds (live on this site)
Each of these is a real, paid route here. A custom build looks like one or more of them, shaped around your data and users.
Token risk verdict $0.01 per call
GET /solana/token-verdict · GET /base/token-verdict
SAFE / CAUTION / DANGER for a Solana or Base token: holder concentration, snipers and bundles, insiders, LP lock, mint and freeze authority, contract flags and sell-route checks. Built from free public sources (DexScreener, GoPlus, RugCheck, Jupiter, public RPC). How it works
Whale flow $0.02 per call
GET /crypto/whale-flow
Large DEX buys and sells over 1-24h across a token's top pools: net flow, accumulation or distribution signal, hourly flow and the top accumulating and distributing wallets. How it works
Token pre-trade pack $0.015 per call
GET /bundle/token-pre-trade
One GO / CAUTION / STOP answer that combines the token verdict, an OFAC screen of the wallet and token authorities, and the wallet's pay-readiness. How it works
OFAC sanctions screen $0.01 per call
GET /compliance/sanctions-screen
Checks a crypto address on any chain and/or a name against the US Treasury OFAC SDN and Consolidated lists, refreshed twice a day. How it works
SEC 13F holdings $0.02 per call
GET /sec/13f-holdings · GET /sec/13f-holders
A fund's latest 13F top positions with quarter-over-quarter changes, and the reverse view: which notable managers hold a stock. Parsed from SEC EDGAR. How it works
CFTC COT screener $0.02 per call
GET /futures/cot-screener
Weekly Commitments of Traders across 45 futures markets: net speculator position, 3-year percentile, crowded long / short flags and the biggest weekly shifts. How it works

FAQ
How long does it take?
Setup Review: about 2 business days. Full Setup: about 5 business days after we have repo access and your receive addresses. Custom builds: usually 1 to 3 weeks depending on scope; the quote includes a date.
What is included?
Working code in your repository, deployment help on your host (Railway or similar), payment wiring on your wallets, discovery files and free directory listings, plus a short handover note on how to run and change it. Custom builds include tests and one revision round. Not included: ongoing hosting bills, paid placements or new features after handover (we can quote those separately).
How do I pay?
Review and Full Setup are paid up front through Stripe checkout (card). For custom builds we send a fixed quote first; once you accept, we invoice 50% to start and 50% on delivery through Stripe. If a Full Setup turns out larger than $750 we tell you before doing the extra work, and you can stop at that point.
Do you hold our funds or keys?
No. You keep your wallets and accounts. We never create wallets for you or custody funds. We need receive addresses and, for deploys, access you grant and can revoke.
Which chains and stacks?
x402 on Base and Solana with USDC, Stripe MPP on Tempo, Node.js and Express APIs, the MCP TypeScript SDK and ElizaOS plugins. Other stacks: ask in the form.
Is the data investment advice?
No. The routes we build return informational data and checks. They are not investment, legal or tax advice.
