Daily total value locked history for one chain or for all of DeFi, up to ten years of points, with latest, first, minimum, maximum and mean and the change over the window. Use it when an agent is charting a chain's growth or checking whether a TVL move is new or a return to trend.

List EAS (Ethereum Attestation Service) attestations for an address as recipient, attester, or either, on mainnet/Base/Optimism/Arbitrum/Sepolia. Returns attestation id, attester, recipient, schema id, revocable/revoked flags, timestamp, and decoded data JSON. Use to verify Gitcoin Passport stamps, Coinbase verifications, KYC attestations, or any other on-chain claim about an address.

The live feed a Kalshi event settles on, from Kalshi's free live_data tier: a crypto event returns the CF Benchmarks price series, candlesticks (15M, 1M) and the maturity time; an economic-data event (CPI, jobs) returns the provider's series with the target period. Pass an eventTicker, or a seriesTicker (e.g. KXBTC) and the soonest open event is resolved for you. The type field names the schema of details.

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.

Pull emails, URLs, IPv4s, @mentions, and #hashtags out of free text. Returns deduped lists.

Get full detail for a single Kalshi event with all its nested markets. Mutually-exclusive flag tells you whether the markets partition outcome space (e.g. one winner). Useful for: viewing all candidates in an election, all CPI ranges, all weather buckets.

Check whether an email address has a Gravatar: hashes the normalized email (MD5, pure CPU - the raw address is never sent upstream), probes gravatar.com for an avatar, and fetches the public profile when one exists (display name, username, profile URL). Accepts a raw email or a precomputed MD5/SHA-256 hash. Signal-only: a Gravatar's existence suggests a real, web-active address but does NOT verify identity or deliverability - pair with /api/email-validate for MX checks.

End-to-end email-auth report for a domain: SPF + DMARC + DKIM (probes common selectors automatically) + MX records + score 0–100. The one call to make when 'why is our mail going to spam?' lands in your inbox.

Reverse-resolve a batch of Ethereum addresses to ENS primary names + avatar URLs (up to 50 per call). Returns one row per address with name (or null), displayName (with checksum if no name), and avatar URI. Use to label transaction lists, wallet leaderboards, or NFT holder snapshots with human-readable names instead of 0xabc… stubs.

Last N MEV-Boost-built blocks from a major MEV-Boost relay's public data API. For each block: slot, block number/hash, builder pubkey, proposer pubkey, gas used/limit, ETH paid to the proposer, and tx count. Use to monitor block-builder market share, proposer revenue, or to correlate an arbitrage opportunity with the block it landed in.

Share your namespace with another wallet so different agents can coordinate through it. Grant read or readwrite access to a grantee wallet, optionally with a TTL. This is the cross-agent sharing a single agent cannot provide for itself.

Onchain options protocols ranked by 24h notional volume with 7d and 30d volume, 1d and 7d change and the chains each runs on, plus sector totals. Use it when an agent is comparing decentralized options venues or tracking whether onchain options activity is growing.

Builder market share aggregated over the last N MEV-Boost blocks from a major MEV-Boost relay's public data API. Returns per-builder block count, share percent, total ETH paid to proposers, and average per block. Use to track block-builder concentration or detect a new builder gaining share.

Score an OpenAPI 3.x or Swagger 2.x spec on agent-readiness - i.e. does an LLM-driven caller have what it needs to call the API correctly without guessing. Returns a 0..100 score, severity counts, and a structured list of violations with stable rule codes. Checks: documented title/servers/paths, per-operation summary/description/operationId/tags, documented 2xx + error responses, param descriptions/schemas/examples, response descriptions, JSON response schemas.

List Kalshi markets (CFTC-regulated US event contracts). Filter by status (open/closed/settled/unopened) or by event ticker. Returns yes/no bid/ask, last price, volume, open interest, and the resting contract size at the best yes bid and ask (yesBidSize/yesAskSize). Covers US-regulated markets and Kalshi-only categories (weather, economic data).

Top L2s by Total Value Locked (TVL) from an open DeFi analytics API. Returns each L2 with TVL in USD, native token symbol, and market-data coin ids. Classification combines the source's parent-chain hint with a curated list of well-known L2s (Arbitrum, Optimism, Base, zkSync Era, Linea, Scroll, Mantle, Polygon zkEVM, Starknet, Blast, Mode, Manta, Metis, Polygon, Taiko, Immutable zkEVM, World Chain).

Build a runnable curl command for one operation in an OpenAPI 3.x or Swagger 2.x spec. Locate the operation by operationId (preferred) or by method + path, substitute path parameters using the spec's example values, include required query and header parameters with their example values, and attach a JSON body when the operation defines one. Returns the structured request (method, url, headers, body) alongside the assembled curl string with POSIX single-quote escaping.

Compute a precise age (years, months, days) from a birth date to today (or a given date), plus total days.

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

Break-even point for a product: the units and revenue at which total revenue covers fixed plus variable costs. Also returns contribution margin and margin ratio.
