Otto AI x402 — Market Intelligence, DeFi & Trading

Schedule 13D and 13G activist stake filings by ticker: every beneficial-ownership filing made about a US-listed issuer in the last 365 days, each validated against its own cover page so a company's outbound filings about OTHER companies are excluded. Returns 13D vs 13G counts, amendments, reporting-person names and EDGAR links. 13D is the schedule filed without a passive/qualified certification. Public-domain SEC EDGAR. $0.005 per call.

8-K filings by ticker — the item-coded SEC material-event feed: every 8-K a US-listed company filed in 90 days, tagged with the SEC's own item codes and official titles (1.01 material agreement, 1.05 cybersecurity incident, 3.01 delisting notice, 5.02 officer change, 8.01 other). Returns event and filing dates separately, amendments labelled, EDGAR links. Earnings-only filings excluded and counted. Public-domain SEC EDGAR. $0.003 per call.

Base-chain ecosystem news for Base-native agents, not the general crypto firehose. Up to 12 Base-scoped headlines from the last 48h, each with its own permalink and publication timestamp, screened against the general /crypto-news feed; `screen` states what was dropped. The AI topic read is optional and is withheld, never padded with macro, when there is no Base coverage. Refreshed hourly from cache; a read past the freshness window pulls inline.

Cross-chain token bridging via LiFi aggregator. Move tokens between Base, Ethereum, Arbitrum, Optimism, Polygon, BSC, Avalanche, and Solana with best-route execution across all major bridges.

Base chain status from Otto's own RPC: the four heads an agent needs before it acts — latest (~2s soft), safe, L1-finalized and the pending Flashblocks preconfirmation head — with base fee (wei+gwei), congestion, block age and the finality lag between them. Makes the Base pending-vs-latest gap explicit. Flat JSON, refreshed every minute, honest staleness meta. Base chain status, block height, base fee, finality, chain health. $0.001 per call.

Close an open perpetual position on Hyperliquid (full or partial). Cancels all attached TP/SL trigger orders automatically.

Deposit USDC into your non-custodial Otto AI Safe on Base. Dynamic price per request = deposit amount + $0.01 service fee (the amount you deposit is paid via x402). The $0.01 shown here is the floor service fee for discovery only.

Resolve any domain in one call: A/AAAA, MX, NS, CNAME, SOA and TXT records, plus parsed email-auth posture — SPF policy, DMARC policy, and detected DKIM selectors. A drop-in nslookup/dig replacement for agents, resolved over DNS-over-HTTPS (DoH) with redundant resolvers and automatic failover. Keyless, pay-per-call, structured JSON.

Smart-money bundle for any US-listed company by ticker, in ONE call: SEC Form 4 insider activity (purchases vs sales — SEC codes P/S, net purchase-sale balance, who filed and their roles) PLUS trailing-twelve-month fundamentals (revenue + YoY, net income + YoY, diluted EPS) from XBRL filings. 4/A-amended insider windows withheld once detected (~1h lag): unpaid 503. Smart money, fundamentals. Public-domain SEC EDGAR. $0.006 per call.

Otto X402 Router — Feedback & Refunds. Rate a paid Router call by its payment tx_hash. An approved refund returns this $0.001 fee PLUS the refundable amount, only to the original payer, never above what you paid Otto.

Full SEC financial statements for any US-listed company by ticker: income statement, balance sheet and cash flow, five periods deep, annual and quarterly. Every figure names its XBRL concept, its filing and date, and whether it was filed, derived from year-to-date figures or computed; restatements flagged with the earlier value; unreported cells explicit. Plus the filing index (10-K/10-Q/8-K, item codes). SEC EDGAR, public domain.

Latest insider trades feed across ALL US-listed companies — the 20 most recent SEC Form 4 filings by acceptance time, not one ticker at a time: issuer ticker and name, filer and role, transaction code (P purchase / S sale / A award / M exercise / F tax), shares, price, value and shares held after, with EDGAR links. Refreshed every 15 minutes. Filings with no Table I rows are excluded and counted. Public-domain SEC EDGAR. $0.003 per call.

Otto X402 Router — Full Auto. The router picks the best-matched Otto service for your ask and pays it on your behalf at-cost plus a flat $0.001 fee, under an `upto` cap (settles actual, never above your cap) — no prepay, no held balance, per-call pass-through; briefly in the payment path, so not 'non-custodial.' Send an X-Idempotency-Key.

Base gas oracle from Otto's own RPC: current base fee (wei+gwei), legacy gas price, and slow/standard/fast EIP-1559 priority-fee tiers (p25/p50/p90 over the last 20 blocks) with a ready-to-sign maxFeePerGas per tier. Unlike the crowded gas shelf it PUBLISHES the formula, so every tier is reproducible from the response. Flat JSON, refreshed every minute. Base gas oracle, gas price, priority fee, EIP-1559, maxFeePerGas. $0.001 per call.

AI image generation and editing via fal.ai, including memes. model: gpt-image-2 (default) | nano-banana-pro; anything else -> 400. Flat $0.15 per image. Supports image editing via public image URL.

Deposit or withdraw USDC to/from Hyperliquid via Arbitrum. Intelligent routing: checks Arbitrum Safe first, auto-bridges from Base if needed, falls back to Butler wallet.

Full holder analytics for any Base ERC-20: total holders with 24h/3d/7d/30d holder-change momentum, whale-tier distribution, acquisition mix (swap vs transfer vs airdrop), top-10/25/50/100 supply share, labeled top holders with concentration (top1/5/10/20% + contract-held%) and an AI concentration-risk read. Bag check, holder analytics, holder concentration, whale distribution. $0.03 per call.

A tight 4-6 sentence crypto market recap an agent can ingest whole — direction and why, the 2-3 developments that matter, anything notable on the top-10 board — plus the ranked stories as typed fields: stories[] (rank, title, whyItMatters, url, publishedAt, source; linked by exact title, null when unmatched). Distilled from the Otto news engine; served while fresh, refreshed on demand.
