# Vextorium

> Pay-per-call data APIs for AI agents over x402 (USDC on Base, Solana or Polygon). No accounts and no API keys: send the request, receive an HTTP 402 with the price, pay, and get JSON.

## How to call

- Every endpoint is POST with a JSON body and returns JSON.
- An unpaid request returns HTTP 402 with a PAYMENT-REQUIRED header (x402 v2). Pay with any x402 client, e.g. `npx awal x402 pay <endpoint> -X POST -d '<json>'`.
- Requests that fail (invalid input, not found, upstream source down) return 4xx/5xx and are not charged.
- Machine-readable list with input examples: https://api.vextorium.com/catalog.json
- OpenAPI 3.1 spec (all paid operations, input schemas, prices): https://api.vextorium.com/openapi.json
- MCP server (Streamable HTTP, for Claude, Cursor and other MCP clients): https://api.vextorium.com/mcp — free tools search_services and service_details, paid tool call_service (x402).

## Agent workflows (start here)

Pick the workflow that matches your task and call the services in this order. Prices are per call in USDC.

### Trading bot: screen and monitor tokens (Solana, Base, Ethereum, Arbitrum, Optimism, Polygon)
1. Find candidates: /v1/new-safe-tokens (new launches already filtered by safety and real volume).
2. Screen in bulk: /v1/token-safety-batch (up to 25 tokens per call, $0.02) and /v1/wash-trading (wash-trading check).
3. Before buying: /v1/pre-trade-check (risk + liquidity + price impact + recommended slippage).
4. While holding, every few minutes: /v1/position-check (pass your entry liquidity and score) and prices with /v1/token-price-batch (up to 50 tokens, $0.003).

### Due diligence on a wallet or counterparty
1. /v1/wallet-identity (labels, scam flag, contract or wallet). 2. /v1/wallet-sanctions-check (OFAC) and /v1/sanctions-screening (EU/OFAC names). 3. History: /v1/evm-tx-history or /v1/solana-wallet-profile.

### Portfolio tracking
/v1/wallet-portfolio (every ERC-20 with USD value) or /v1/evm-balance-12-chains; Solana: /v1/solana-wallet-value; prices in bulk: /v1/token-price-batch.

### Market context for crypto decisions
/v1/market-regime (risk-on/off in one call), then /v1/funding-rates, /v1/hyperliquid-whales and /v1/crypto-news.

### Macro and rates
/v1/economic-calendar (what is coming), then /v1/us-treasury-yield-curve, /v1/fed-rates, /v1/us-cpi, /v1/ecb-interest-rates.

### Compliance / KYB
/v1/lei-search, /v1/sanctions-screening, /v1/un-sanctions, /v1/wallet-sanctions-check, /v1/eu-vat-vies.

### Research and grounding
/v1/wikidata-entity (facts), /v1/wikipedia-summary, /v1/scholarly-search (papers), /v1/web-to-markdown (read a web page).

### Developer helpers for agents
/v1/json-repair (fix LLM JSON), /v1/build-transaction (unsigned EVM tx), /v1/tx-decode (explain a tx).

### Using AgentCash or another x402 MCP wallet
discover_api_endpoints("https://api.vextorium.com") → check_endpoint_schema on the chosen endpoint → fetch. Or connect the MCP server https://api.vextorium.com/mcp (free search and schema tools, paid call_service).
