Salt Edge Account Information

5,000-plus banks in more than 50 countries, by Salt Edge's own count. Rate limit exceeded returns HTTP 406 RateLimitExceeded, not 429.

Yapily

llms.txt, llms-full.txt, a no-auth docs MCP server and an OpenAPI file. No public pricing; live access starts with a sales form.

Salt Edge Account Information

1. Treat HTTP 406 with error_class RateLimitExceeded as a rate limit and back off; it isn't a content-negotiation error
2. Start with fakebank_simple_xf in country XF; it needs no bank sandbox
3. Sign requests from the start even in Test, so the move to Live doesn't change your client
4. Follow next_page from the meta block rather than building from_id URLs yourself
5. Revoke with PUT /api/v6/consents/{consent_id}/revoke when the user is done

Yapily

1. Read llms-full.txt once and cache it; it's the whole documentation in one fetch
2. Add the Modelo sandbox in the Console before your first account-auth-request, or institutions comes back empty
3. Treat a 403 on a data call as a revoked or expired consent and send the user back through authorisation
4. Check the error source field first; USER and INSTITUTION failures won't clear on retry
5. In the UK, call extend-consent with lastConfirmedAt before the reconfirmBy date, or the consent lapses at 90 days
