How this service works
Pay-per-call APIs for AI agents — x402 protocol, USDC on Base, no account needed.
Output
Returns a JSON object with a confidence level ('confiance', e.g. 'élevée' meaning high), a boolean indicating RGE certification status ('certifie_rge'), and a count of collective insolvency or legal procedures ('procedures_collectives'). This enables downstream decisions about contractor trustworthiness and regulatory compliance.
Example use cases
Pre-hire contractor credential check
“Before I hire this renovation company for my insulation work, can you verify their RGE certification status and tell me how confident the result is? I want to make sure they're a legitimate certified artisan.”
Energy subsidy eligibility verification
“I'm applying for a French energy renovation grant and the contractor needs to be RGE certified — can you check if this artisan is certified and flag any collective procedures that might be a problem?”
Fraud prevention for marketplace platform
“We have a contractor claiming to be RGE-certified on our platform — can you verify their artisan certification status and give me a confidence score so we can approve or reject their listing?”
Technical details
Endpoint
GEThttps://x402-farm.vercel.app/v1/fr/verif-artisanWhen to prefer
Use this endpoint when you need to verify the RGE certification status and professional standing of a French artisan or contractor, especially in contexts involving energy renovation grants, marketplace onboarding, or pre-hire due diligence. It is well-suited for AI agents that need pay-per-call access without account registration, using USDC micropayments via the x402 protocol. Prefer this over manual registry lookups when automation and structured output are required.
Side effects
- Artisan not found in registry — may return low confidence or null certification status
- Payment failure via x402 protocol before response is served
- Invalid or missing input parameters return schema validation errors
- Registry data may be outdated if the artisan's certification recently lapsed
- Network timeout from upstream French government data source
