Get open and historical positions for a wallet address

Multi-chain JSON-RPC passthrough fronted by BlockRun, powered by Tatum's gateway across 40 chains (Ethereum, Base, Solana, Polygon, BSC, Arbitrum, Optimism, Avalanche, Bitcoin, Sui, and more). One endpoint, every chain, pay-per-call in USDC, no API key. $0.002 per call (or per element of a JSON-RPC batch). Network: Ethereum.

The 'user uploaded a thing, normalize it before storing' workflow. Probe the file (image or audio/video) with media-info, decode any embedded barcodes/QRs, resize and thumbnail the image, convert it to a web-friendly format, and normalize audio loudness to broadcast standard. Six tools, one canonical normalize-on-upload pipeline that turns arbitrary user uploads into predictable storage artifacts.

Turn arbitrary URLs and PDFs into clean structured text - articles, page metadata, PDF pages, OCR'd images, browser-rendered SPAs. Content extraction skill pack: one x402 payment runs 6 underlying tools (extract, meta, pdf-to-markdown, pdf-extract-pages, render, image-ocr); partial-success per step.

WhiteMagic hosted recall — agent memory for cross-session continuity: read-only hybrid search (BM25 + vector + associative) over a curated public corpus. Call when an agent needs durable context from prior sessions or the public knowledge store. Keyless discovery (initialize/tools/list) is free; free evaluation keys and a daily no-key trial are available. One paid tool call per payment.

Screen a person or company name against the OFAC SDN list. Returns exact and substring matches with the SDN entry id and type, so every hit can be checked against the published list itself. Matching is exact, substring, or all-tokens (every word of your query appears as a whole word in the entry, in any order - so 'Vladimir Putin' finds 'PUTIN, Vladimir Vladimirovich').

Ask Base anything in one paid call: your SQL runs against indexed, DECODED chain data (events with parsed parameters, transactions, blocks, user-ops) with the live schema alongside - no indexer, no RPC archaeology. Onchain analyst (SQL over Base) skill pack: one x402 payment runs 3 underlying tools (onchain-sql-schema, onchain-sql, stats-summary); partial-success per step.

Side-by-side snapshot of a stock and a crypto asset: the equity's latest close against a live crypto quote, a trailing-year series for each, and a date-stamped comparison. Cross-asset price monitor skill pack: one x402 payment runs 5 underlying tools (stock-quote, stock-history, crypto-price, crypto-history, date-format); partial-success per step.

Search Farcaster casts by keyword (literal, semantic or hybrid match), newest first, optionally filtered to one author or channel. Returns compact casts: hash, author (fid, username, follower count), text, timestamp, channel, reactions, reply count, embed URLs. Use for mention monitoring, sentiment sampling, or finding discussion of a token, product or topic.

Google's native generateContent wire on the base tier. Send Gemini's own request shape (contents, systemInstruction, generationConfig, function declarations) and get Gemini's own response shape (candidates, usageMetadata) back. Point a Google GenAI SDK at this gateway and pay per request with USDC, no account. Also answers the Google-shaped path /v1beta/models/<model>:generateContent.

Anthropic Messages API over x402 - point the Anthropic SDK (or Claude Code / the Agent SDK) at base_url https://agent402.tools/v1 and pay $0.02 per call in USDC, no API key, no signup. Same models, caps and price as this tier's /chat/completions route; any model here is served through the Messages wire (Claude natively, others translated). Depth: `effort` (low..max) on Claude 4.7+ and Haiku 5.5, thinking.budget_tokens on older Claude.

Latest casts in one or more Farcaster channels (e.g. base, farcaster, ethereum), newest first, with optional replies. Compact cast shape with author, reactions, reply count and embed URLs. Cached 60 s per identical request. Use to watch a community, sample what builders are posting, or feed a digest.

Your own settled calls in the shape a finance system posts: one row per payment with what was bought, the amount settled, the quoted ceiling where one applied, and the evidence - settlement transaction, sha256 of the bytes delivered, and the on-chain attestation id where one exists. Keyed to the wallet that pays for the call, so nobody can read another wallet's payables; no account, no export request, no support ticket. Requires an EIP-3009 payment (USDC on Base, Polygon, or Arbitrum).

Crop an image to a pixel box, and/or rotate (90/180/270) and flip it - applied in that order. Send a public image URL or a base64 image. Returns the result as binary, or as a JSON data URI with dataUri:true. Deterministic.

Look up the native coin balance (ETH/MATIC) plus every ERC-20 holding for a wallet address on Ethereum, Base, Polygon, Arbitrum, or Optimism. Returns clean decimal balances (already scaled by token decimals) plus symbol and contract - ready to display in a UI or feed into a portfolio tool.

Look up the Autonomous System (ASN), prefix, country, registry, and allocation date for an IPv4 address - or for a hostname (which is resolved first). Uses a free public DNS-based IP→ASN mapping service; no HTTPS upstream, no auth, no rate-limit headaches.

Mask emails, phone numbers, credit-card-like numbers, IPs, and SSNs in text. Returns the redacted text and counts by type.

Probe any URL and decode its HTTP 402 payment requirements (price, asset, network, pay-to) into clean JSON - what an agent needs to decide whether/how to pay. Read-only; does not pay.

Is this blockchain address on the OFAC SDN list? Screens any address against every Digital Currency Address OFAC publishes (Bitcoin, Ethereum, Tron, USDT, USDC, Monero, Litecoin and more). A match names the sanctioned entity and its SDN id. A miss is reported as 'not on the lists checked, as of this date' and is never a clearance - the answer carries that caveat in the payload. Deterministic: a cached copy of the published list, no model in the path.

Validate an A2A (Agent2Agent protocol) Agent Card: required fields, skill shape, transport names, capability flags - spec v0.3 structural core. Returns errors, interop warnings, and a normalized summary (skills, interfaces, capabilities). Deterministic mini-A2A tooling - check a card before your agent trusts it.
