Electra publishes no rate limits, and returns no rate-limit signal of any kind on the wire. A roaming partner polling the locations or tariffs module has no documented budget and no runtime feedback, so the only available strategy is to back off on failure — and even then, the 401/404 responses carry no Retry-After. limits: [] headers: observed: [] x_ratelimit_family: false ietf_ratelimit_family: false retry_after: false detail: >- The full response header set observed on the anonymous 200 was: date, content-type, content-length, x-frame-options, x-xss-protection, x-content-type-options, x-download-options, x-permitted-cross-domain-policies, referrer-policy, vary, etag, cache-control, content-security-policy, x-request-id, x-runtime, strict-transport-security, cf-cache-status, server, cf-ray. Not one rate-limit field among them. exhaustion_status: null exhaustion_note: >- No 429 was observed and none is documented. Electra sits behind Cloudflare (server: cloudflare, cf-ray present), so an undocumented edge rate limit or bot rule may exist; nothing about it is published, and nothing is asserted here. mitigations_available_to_a_client: - >- The versions endpoint returns a weak ETag (W/"5a4f9da10b50e8577b67e23eeee192d1") and cache-control max-age=0, private, must-revalidate, so a conditional GET is possible for version negotiation — the one place a polling client can be a good citizen without guidance. - >- Every response carries x-request-id and x-runtime, which at least gives a partner something to quote when raising a throttling question through a commercial channel. gaps: - No published limits. - No runtime headers. - No documented 429 behaviour and no Retry-After.
