Agentic Payments MCP
info.blocksize.mcp/agentic-payments is a MCP server that exposes Blocksize public market data, pricing, and docs for agentic payment integrations.
About
info.blocksize.mcp/agentic-payments is a Model Context Protocol server that exposes Blocksize’s public discovery layer for market data, pricing, and documentation to coding agents. Developers adding payments, usage-based billing, or agent-initiated commerce can keep the agent aligned with current Blocksize APIs instead of hallucinating endpoints or stale fee tables. Register the hosted streamable-http MCP during backend and integration work, and revisit it when you validate pricing models or debug production payment flows. It is narrower than a full payment SDK: it is an MCP bridge for discovery and reference data that agents call during implementation. Pair it with your own secret management and PSP contracts; the server description emphasizes public discovery rather than holding card data in the MCP layer.

What it does
Wire Blocksize market data, pricing, and payment docs into your agent while designing agentic checkout or fintech integrations.
Who is it for?
Best when you're shipping agentic or API-first products that depend on Blocksize market data and payment documentation.
Skip if: Products that need a full hosted checkout UI with no Blocksize dependency or developers avoiding external financial data providers.
What you get
Your agent can query Blocksize discovery through MCP so integration prompts reference real market data and documentation paths.
- Live MCP link to Blocksize discovery endpoints
- Agent-grounded integration prompts using current docs and pricing context

Public tool metadata - what this server can do for an agent.
search_pairs2 paramsDiscover supported crypto, equity, FX, and metal symbols before using the paid HTTP API. Returns up to 50 catalog matches with asset class, available services, and pricing tier; it is free, read-only, and never returns live prices or starts payment.
querystringrequiredSymbol, ticker, asset, or pair to search for, such as BTC, BTC-USD, ETH, AAPL, EURUSD, or XAUUSD.asset_classstringOptional asset-class filter. Use all for the full catalog, crypto for digital assets, equity/equities for supported stock tickers such as AAPL, fx for currency pairs, or metal for metals.
list_instruments1 paramList the supported instruments for one Blocksize service. This is free, read-only catalog metadata; it does not fetch live prices, create accounts, or start x402 payment.
servicestringBlocksize service namespace to list: vwap for crypto VWAP pairs, bidask for shared bid/ask symbols including supported equities, fx for FX pairs, or metal for metals.
get_pricing_infoInspect current per-call prices, bulk credit tiers, and supported Solana and Base USDC settlement networks. This is free and read-only planning metadata; it does not initiate payment.
get_product_catalogInspect Blocksize raw data, supported equity ticker bid/ask, and premium agent-native workflow products, including starter-credit positioning, credit costs, suggested paid prices, endpoint templates, and upgrade path. This is free and read-only.
get_workflow_endpoint1 paramBuild the exact paid HTTP endpoint, method, starter-credit cost, and example body for a premium Blocksize workflow. This is free and read-only; it does not fetch live data, charge credits, or start x402.
productstringrequiredPremium Blocksize workflow product to prepare.
get_market_data_endpoint2 paramsBuild the exact x402-protected HTTP URL for one live market-data request. Returns method, URL, service notes, pricing docs, and next steps; it is read-only and does not fetch prices, charge a wallet, or submit payment.
servicestringrequiredLive HTTP data service to prepare: vwap for crypto VWAP, bidask for crypto pairs or supported equity/stock tickers such as AAPL, state for AMM state price, vwap30m for latest completed 30-minute close, vwap24h for fixed 24-hour VWAP from the stream cache, fx for currency pairs, or metal for metals.symbolstringrequiredExact pair or ticker to use in the paid HTTP URL, such as BTC-USD, AAPL, MSFT, NVDA, EURUSD, or XAUUSD. Use search_pairs first if unsure.
