Clauhub and Facturapi.Which API fits you.

Both let you issue and cancel CFDI 4.0 from your product. Facturapi is a mature invoicing API, with official libraries, webhooks and a test environment. Clauhub is the same API its app uses: besides issuing, it downloads your CFDI from the SAT, checks 69-B and connects to your AI agents over MCP.

Clau beside a scale, comparing two options

The differences, in figures

At today's list prices, with VAT: up to 104 stamps a month, Clauhub costs less (Free plan, you pay only for stamps); from 105 on, Facturapi's API plan costs less, thanks to its lower price per stamp.

What you get in each API, row by row.

Facturapi is an invoicing API with official libraries, webhooks and a test environment. Clauhub exposes everything its app does over API and MCP: issuing CFDI, downloading them from the SAT and checking 69-B.

  • API style and auth[3][8]

    Clauhub

    RPC over HTTP: POST /api/rpc/<domain>/<procedure> with a JSON body. An API key (ch_…) in x-api-key; it acts as the user who created it, with their permissions.

    Facturapi

    REST at https://www.facturapi.io/v2, with the secret key as Authorization: Bearer. Test and live keys per organization, and a user key for the whole account.

When each one fits. Both are good options.

Facturapi fits if

  • You want an official library in Node.js, C#, Java or PHP
  • You need webhooks to hear about stamping and cancellations
  • You want to test end to end with a test key before going live
  • You issue for many RFCs from one integration
  • You stamp more than 104 invoices a month: at list prices, its API plan costs less from there

Clauhub fits if

  • Besides issuing, you need issued and received CFDI downloaded from the SAT, with no charge per CFDI
  • You want to check RFCs against 69-B and 69 from the same API
  • You want your AI agents to issue and query over MCP, with OAuth or your key
  • You stamp little or are starting out: no monthly fee, the Free plan includes 100,000 calls a month
  • Your team also uses the app: the API does what the app does, with the same permissions

Frequently asked questions

How do I authenticate to Clauhub's API?

With an API key (ch_…) in the x-api-key header. The key acts as the user who created it, with the same permissions; it is shown once and stored only as a hash. For MCP you can also connect with OAuth.

Does Clauhub have a test environment or webhooks?

Not yet. You can validate a capture with preview, which computes totals without stamping or storing anything, and follow each document with get and events. If webhooks or a test environment are a must for your integration, Facturapi has them today.

Is there an SDK?

Not for now. The API is HTTP with JSON, so you call it from any language; and every procedure is also an MCP tool for your AI agents.

How much does it cost?

Each stamp costs 0.1664 credits: $2.9952 MXN + VAT ($3.47 with VAT). API calls come with your plan: 100,000 a month on Free and Team, then 1 credit per 100,000; unlimited on Business. Against Facturapi's API plan ($299 a month plus $0.60 per stamp, VAT included): at today's list prices, with VAT: up to 104 stamps a month, Clauhub costs less (Free plan, you pay only for stamps); from 105 on, Facturapi's API plan costs less, thanks to its lower price per stamp.
