Catalog

Every agent-payable API.

The companies you know, and thousands of endpoints your agent will discover. The catalog groups the network's 23,500+payable services under the companies that operate them — one company row can carry many service endpoints. Placement can't be bought.

Connections API
Get business connections for a specific company Pagination billing: call the first page normally and save billing.requestId from the Orthogonal /v1/run response. For later page, offset, or cursor calls on the same logical search, pass parentRequestId with unchanged non-pagination parameters. Valid continuation calls still get their own request IDs and quoted price, but are charged 0. Changing filters starts a new billable request.

Discover connections across portfolio companies Pagination billing: call the first page normally and save billing.requestId from the Orthogonal /v1/run response. For later page, offset, or cursor calls on the same logical search, pass parentRequestId with unchanged non-pagination parameters. Valid continuation calls still get their own request IDs and quoted price, but are charged 0. Changing filters starts a new billable request.

Consensus API
Analyst consensus for one KRX ticker, built from the archived research history: mean/median/min/max target price across brokerages, the spread between them, the rating distribution, and a revision log of every target-price and rating change each house has made. Consensus uses each house's latest view, so a weekly publisher does not outvote a quarterly one. Params: ?window=30d|90d|180d|365d (default 90d).

Constants API
The Standard Reserve (TSR), an on-chain reserve protocol on Robinhood Chain. Chain-read protocol constants: base rate, epoch length, floors, and where each one was last read from.

Contacts API
Collect the emails, phone numbers and social profiles a page visibly publishes.

Container Check API
Validates the ISO 6346 check digit and separates owner, category and serial components. Missing facts are returned as null and named in unavailable_fields where applicable. Derived values disclose their method; source-backed values disclose source, time window and age.
halowerk.com-$0.003listed
Container Load API
Loads a package list into one loading space and returns the plan, not an estimate. The floor starts as one free surface; packages are sorted by footprint, then height, then weight, then identifier, and each one is placed on the lowest, then frontmost, then smallest free surface it fits on, turned by 90 degrees around the vertical axis where that makes it fit.
halowerk.com-$0.006listed
Content API
Fetch a URL with a real rendered browser (JavaScript executed) and return clean Markdown. Results are cached for 24 hours per URL, so repeat calls for the same page are fast and don't re-render.

Contents API
Read any web page as clean LLM-ready markdown for $0.003 — the natural companion to /web/search. Send a URL, get back the readable core: title, headings, paragraphs, lists and links, stripped of scripts, styles, navigation and other boilerplate. Choose markdown or plain text and cap the size with max_chars (default 20000; a truncated flag tells you when the cut hit). Unreachable or non-HTML targets cost nothing. Pay per call in USDC, no account, no API key.

Contract ABI
Fetch a verified contract's ABI and metadata by address, keylessly, from Sourcify. Returns the ABI plus a summarized list of function and event signatures, the contract name and compiler, and proxy detection (is_proxy + implementation address). Block explorers gate the ABI behind an API key; this does not. Chains: base, ethereum, arbitrum, optimism, polygon, bsc, avalanche. No API keys, no LLM, one x402 USDC micropayment per call.
cyberwarex.com-$0.003listed
Contract ABI Lookup
Checks Sourcify for a Base contract's verification status and returns its ABI as function/event name lists + item count (full or partial match). No API key required.

Contract Identity
🆕 What sits at a Base address: contract or plain wallet, and if a contract, whether it declares ERC-721 or ERC-1155 via ERC-165 or carries the ERC-20 shape, plus name, symbol, decimals and code size. Interface support is read from the contract's own declaration first and only inferred when there is none — the ordering matters, because NFTs answer totalSupply() too.

Contract storage slot
Read one 32-byte storage slot from a contract, the raw state under whatever the source code calls it. Returns the word as hex plus three readings of the same bytes - unsigned integer, address (low 20 bytes) and boolean - because a slot is untyped on chain and only the caller knows which it meant. Useful for proxy implementation slots, paused flags and any value the ABI does not expose. EVM chains: ethereum, base, polygon, arbitrum, optimism.
