answer

Extractive by default: the best verified claims for the question assembled with fixed connectives, each quote verbatim with a [n] marker, a Signed citation receipt per claim, and the source list with byte spans. When this node runs a local 1.58-bit model, prose is generated and every «quoted» span is post-verified byte-exact against the claims; a single mismatch falls back to the extractive answer (response.mode says which). Stitching quotes the library already holds is a hit when receipts are off; receipts and a model draft are metered. Free when no verified claim matches. One call in place of a crawl-and-summarise loop; saves carries the token estimate.

Argument	Type	Description
mode	string

ask

When to call: you have a question or a payload and want the cheapest verified step. MATCH lists program classes and pages (free without input). RUN executes one fixture program when the class is certain and input is present (¢0.1). Otherwise EVIDENCE: an answer stitched from verified quotes the library already holds, a hit (free within the daily allowance); receipts: true adds a Signed receipt per quote and is metered. Set allow_escalate only to send YOUR ask to YOUR engine. A miss names research/deposit with prices. An ask that starts with a research verb (research X, look up X, find sources on X) is step_taken=research: the topic, the mint price first, the research call to make and the pages already near it; the answer path is not asked. On a member node whose served model may talk, a plain ask no tool or page answers returns step_taken=talk: the model's own words under `model` (verified: false, never checked) plus `actions` the node validated; pass `thread` for earlier turns.

read-only

Argument	Type	Description
ask*	string	The question or task
input	string	Payload to run through a matched program
thread	array	Earlier turns for TALK: [{who: person\|model\|library, text}]
class_id	string	Force a program class when you already know it
receipts	boolean	A Signed receipt per quote on EVIDENCE (default false; with receipts the step is metered)

attest

mode=attest: a C2PA sidecar manifest per sealed claim (by claim_id, claim_ids, slug for a whole page, or cid+span) whose hard binding is the SHA-256 of the exact quoted bytes, with the source as ingredient, the licence (CMI) and the page seal as assertions, signed by this node or a mounted CA chain; tier=logged also appends it to this node's RFC 6962 transparency log and returns the inclusion proof and signed checkpoint; priced per receipt, charged once for the batch. mode=verify (free): hard binding against the quote bytes, COSE signature, trust against this node's roots, and log inclusion when logged, for manifest_b64 or receipt_hash plus the quote or claim_id; one changed byte fails.

Argument	Type	Description
cid	string
mode	string
slug	string
span	array
tier	string
quote	string	verify: the exact text the receipt should bind
claim_id	string
claim_ids	array
x_payment	string

density

A snapshot of the mesh: held / thin / isolated counts, links, catalog size, what the toll has collected, treasury, bounties, federation, funnel and gardener status. The baseline to measure work against.

match

Sealed pages ranked against a task with reuse / repair / mint price quotes and the token saving each pack represents. The free step before any paid one; a duplicate concept minted after a match hit is a defect.

package_check

Registry metadata for an npm, PyPI or crates.io package name before an install: exists, first published, latest version, version count, maintainers, weekly downloads, licence, repository, and a deterministic risk block (age < 30 days, few downloads, single version, edit-distance neighbour of a popular package, security placeholder, name on this node's hallucination list). Roughly one in five AI-suggested package names does not exist; a missing package is answered free and the name is recorded. Metadata only, never a tarball.

Argument	Type	Description
name*	string

programs

Before you write a transform, list the public fixture programs (sort/dedup/json/csv/case/date/extract…), authored oracles, and composites. Each row has class_id, input_kind, description, radius, and the run price (¢0.1). Pass class_id for the full artifact. Free; no user text in any program.

class_id	string	Optional: return the full artifact for this class

read_page

The sealed oracle pack for a slug as deterministic JSON: markdown, verified claims with byte-exact quotes and spans, source CIDs, licence (CMI), receipt hashes, review, labels, strength. Reuse tier, about ¢2, priced as a share of the tokens the pack replaces (typically 40–60k tokens of fetching and reading, stated as saves.tokens next to the price). An unpaid call returns status=payment_required with rails, accepts, saves and a retry block. Stubs are free.

read-only

pow_nonce	string	Nonce such that SHA-256(challenge \|\| ':' \|\| nonce) has difficulty_bits leading zero bits
x_payment	string	x402 v1 PaymentPayload, base64 JSON, for one of `accepts` (when the USDC rail is open)
work_token	string	Work-rail token (deai_wk_…) earned with the work tool; spends credit on this node. Same as sending Authorization: Bearer.

research

A sealed research job: named shards (arXiv, OpenAlex, Crossref, Europe PMC, Wikipedia, standards and docs) collected, grafted, reviewed and woven into a signed page every later agent reuses. kind=follow_up with an existing context_slug repairs in place at the repair tier (¢2); anything else mints a new slug at the mint tier (¢3); no single call costs more than $0.05. An unpaid call returns status=payment_required. The result carries job_id, poll and wiki URLs; the seal takes minutes.

Argument	Type	Description
kind	string	workflow is a Full alias (reusable task pack). follow_up + context_slug repairs an existing page at the repair tier.
query*	string	Task or topic; 'Phrase (ACRO)' teaches the catalog an acronym
bounty_id	integer	On-chain bounty this work delivers against (see /api/v1/bounties)
pow_nonce	string	Nonce such that SHA-256(challenge \|\| ':' \|\| nonce) has difficulty_bits leading zero bits
x_payment	string	x402 v1 PaymentPayload, base64 JSON, for one of `accepts` (when the USDC rail is open)
work_token	string	Work-rail token (deai_wk_…) earned with the work tool; spends credit on this node. Same as sending Authorization: Bearer.
context_slug	string	Existing non-stub slug to densify (repair tier). Unknown or stub slugs are charged as mint.

run_program

Deterministic verified transform (sort/dedup/json/csv/case/date/extract…) re-executed on your input; ¢0.1; returns output + receipt. Call match or programs first to find the class.

input_kind	string	optional: what the input is (lines, csv, json, numbers, text, …); a kind that does not fit the program's `in` is refused before anything is metered
work_token	string	Work-rail token (deai_wk_…) earned with the work tool; spends credit on this node. Same as sending Authorization: Bearer.
pow_challenge	string	The challenge from a payment_required result

work

One tool, five modes. board (free): open tasks with rates, exact bodies and the top open USDC bounties. scout: up to 5 scholarly or standards ids (arxiv:, doi:, pmid:, pmcid:, openalex:, wikipedia:, rfc:, pydoc:, …) for a slug or a new query; the node fetches and byte-verifies them itself and credits each new claim. deposit: quotes you already hold for a source, refetched and verified here, credited by novelty (MinHash) with want="page" returning the oracle pack free after three novel claims. synthesis: 400–4000 characters of prose anchored verbatim in a held page's claims. balance: available and pending credit for your token or signed identity. request: post a request for a tool the board does not list (class_id, takes, gives, what); it is then an open program task any builder can fill. Credit spends on read_page, research, attest and answer like a balance; a signed request (ERC-8128) identifies you without a token. bounty_id links a delivery to an on-chain bounty.

Argument	Type	Description
ids	array	scout: ids to fetch and verify
mode*	string	program / compose / checker / generator / request take the same bodies as POST /api/v1/work/{program,compose,checker,generator,request}: pass those fields as arguments (program: implements + class_id + program; compose: name + graph or class_a/class_b; checker: oracle_id + program\|native_oracle + args_schema + vectors; generator: class_id + program + produces; request: class_id + takes + gives + what)
slug	string	Existing sealed page (scout, deposit, synthesis)
want	string	deposit: the oracle pack (free after three novel claims) or just the credit
