Tomba
The Tomba API provides programmatic access to email discovery, verification, enrichment, and company intelligence workflows. Find professional emails, validate deliverability, retrieve sources, and automate prospecting at scale using simple REST endpoints.
Getting Started
To begin, send authenticated requests using your API credentials in the request headers. Start with domain search or email finder, then verify addresses and enrich contacts as needed for your workflow.
Code
Rate Limits
Rate limits are enforced per endpoint and per plan across three dimensions: per-second (rps), per-minute (rpm), and per-day. Your daily limit equals your monthly credits divided by 5.
| Plan | Per Second | Per Minute | Per Day |
|---|---|---|---|
| Free | 1 | 2 | 5 |
| Basic | 3 | 50 | 500 |
| Growth | 5 | 80 | 1,000 |
| Pro | 8 | 150 | 4,000 |
| Pro Plus | 10 | 200 | 10,000 |
| Scale | 15 | 300 | 20,000–60,000 |

Rate Limit Headers
Each API response includes these headers:
RateLimit-Policy: Rate limit policies with quota and window (e.g."rps";q=8;w=1, "daily";q=4000;w=86400)RateLimit: Remaining quota and time until reset (e.g."rps";r=7;t=1, "daily";r=3842;t=64802)x-second-rate-limit: Total per-second request limitx-minute-rate-limit: Total per-minute request limitx-daily-rate-limit: Total daily request limitx-minute-request-left: Remaining requests for the minutex-daily-request-left: Remaining requests for the dayx-minute-reset-seconds: Seconds until minute limit resetsx-daily-reset-seconds: Seconds until daily limit resetsRetry-After: Seconds to wait (on 429 responses only)
When any limit is exceeded, the API returns 429 Too Many Requests with a Retry-After header.
Check Your Usage
Use GET /v1/rate-limits to see your current usage per endpoint.
