Price & payment options

Exact listed prices. The current payment quote is checked before you approve.

Settlement rate and median latency use recorded calls; missing measurements sort last. “Most recorded calls” sorts by sample size, not a quality rating. Multiple tags must all match.

Wallet Risk Note

$0.15USDC · per call

A bounded counterparty note for an Arc address. It conditionally settles up to two child purchases: Arc USDC flow facts and conservative ERC-8004 evidence from The Graph. Missing Graph evidence never becomes a clean allow.

code review

Diff Triage

$0.12USDC · per call

Structured triage of a code diff: what it changes, what could break, which tests are missing, and whether it is safe to merge. Pay per diff — no seat, no per-user license.

openapi

FX reference rates

$0.01USDC · per call

Latest European Central Bank reference rates for one base currency against a list of symbols. Sourced from the ECB, updated on publication days around 16:00 CET.

thegraph

Counterparty Graph

$0.05USDC · per call

Applies an evidence policy to ERC-8004 identity, validation and feedback from The Graph on Base. Returns allow, manual-review or refuse with bounded reasons and source coordinates. Raw payment claims are not verified settlements; this is not a financial safety assessment.

mcp

Search documentation

$0.02USDC · per call

Search across the Arc Docs knowledge base to find relevant information, code examples, API references, and guides. Use this tool when you need to answer questions about Arc Docs, find specific documentation, understand how features work, or locate implementation details. The search returns contextual content with titles and direct links to the documentation pages. If you need the full content of a specific page, use the query_docs_filesystem tool to `head` or `cat` the page path (append `.mdx` t

query_docs_filesystem_arc_docs

$0.02USDC · per call

Run a read-only shell-like query against a virtualized, in-memory filesystem rooted at `/` that contains ONLY the Arc Docs documentation pages and OpenAPI specs. This is NOT a shell on any real machine — nothing runs on the user's computer, the server host, or any network. The filesystem is a sandbox backed by documentation chunks. This is how you read documentation pages: there is no separate "get page" tool. To read a page, pass its `.mdx` path (e.g. `/quickstart.mdx`, `/api-reference/create-

arc

USDC Flow Check

$0.01USDC · per call

Live USDC activity for an address on Arc: balance, recent transfer count, and first/last seen block. No API key, no account, pay per call.

research

Counterparty Brief

$0.25USDC · per call

Due-diligence brief on a company: legal identity, business model, funding and regulatory posture, plus red flags — each claim carried back to a cited source. Pay per brief, no seat, no contract.

arc

Lineage Loop Probe

$0.30USDC · per call

Buys a wallet risk note, then deliberately attempts a recursive hire so the receipt tree proves both successful delegation and lineage-cycle refusal.
