A reference guide for working with the Jaz REST API, the web interface developers use to connect software to Jaz accounting. It covers data fields, responses, errors, searches, pagination, and accounting records.

It helps build, review, and debug connections that handle invoices, bills, credit notes, journals, cash entries, payments, accounts, and other Jaz data.

It reduces integration mistakes caused by unclear field names, unexpected responses, authentication paths, and edge cases.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5	$0.00121	$0.28162
Opus 5	$0.00060	$0.14081
Sonnet 5	$0.00024	$0.05632
Haiku 4.5	$0.00012	$0.02816

Measured 3d ago against content hash 1045e1ea1562, method: parsed. Prices are Anthropic first-party input rates as of 2026-08-30, from the pricing page.

Security

Grade A, and why

jaz-api scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 553 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Jaz API Skill

You are working with the Jaz REST API — the accounting platform backend. Also fully compatible with Juan Accounting (same API, same endpoints).

Pick the right invocation path first

Before touching this skill's HTTP details, check what's actually available:

Running inside an MCP host (Claude Desktop, Cowork): use the MCP tools (execute_tool with create_invoice, list_bills, etc.). Do not write direct HTTP. The MCP server handles auth, retries, and field shape for you.
Running Claude Code with the jaz-clio CLI: use the CLI commands (clio invoices list --json, etc.). Same code path, structured output.
No agent surface, raw integration: write HTTP calls per the endpoints catalog below.

The rest of this skill — field names, gotchas, error catalog, dependency order, search filter syntax — applies regardless of invocation path. Read it for context, not for HTTP-call construction unless you're in the third bucket.

Reading Order

Core fundamentals (read first, every integration): Identifiers & Dates 1–3; Names & Fields 9–13; Transaction Creation 14–16; Chart of Accounts 17–22; Payments / Cross-Currency 4–8; Journals & Cash 23–26; Credit Notes & Refunds 27–28; Reports 36–37; Tax Profile Scoping 100; Transaction References 104; Draft Finalization Pipeline 81–88; Jaz Magic / PDF-JPG 57–63; Currency Rates 39, 49, 105; Withholding Tax 45, 98.

Integration depth (API clients, pipelines, batch jobs, MCP/CLI): Bulk Upsert (Items/Contacts/Rates); Background Jobs (filter resourceId not jobId); Export Records; Pagination (38); Search & Filter (50–56); Response Shape Gotchas (66–73); Cash Entry Response Shape (74–77); Entity Resolution (78–80); Bank Rules (89–90c); Fixed Assets (91–92c); Subscriptions & Scheduled (93–94); niche endpoints (95–102); Journals balance (103); Quick Fix (107, 111); TTB (108); Dynamic Strings (109–110); Sub-Resource Shapes (112); Nano-Classifier (113); Scheduler Asymmetry (114); Payment Record CRUD (115–117); Bulk Upserts transactions (118–122); Reconciliation write-side (123–127); Drafts lifecycle (128–135); Orders — Sale Quotes / Sale Orders / Purchase Requests / Purchase Orders (references/orders.md); Claims — records / lifecycle / bulk + conversion + payouts + Employees + Claim Settings (references/claims.md).

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

jaz-api is a skill published in the GitHub repository teamtinvio/jaz-ai (7 stars, last pushed 6d ago), licensed MIT. It adds 121 tokens to every session and 28,162 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
