OMNI Datastream vs sec-api.io
A direct comparison of the two leading SEC data APIs for developers and AI agents.
Speed
Two independent benchmark runs, each with its own OMNI baseline measured at the same time as the competitor. OMNI p50 has improved between runs (production performance is not static) — each table’s speedup uses the OMNI value measured alongside that competitor, not across runs.
vs sec-api.io (benchmark captured 2026-03-18)
| Operation | OMNI p50 | sec-api.io p50 | Winner |
|---|
| Entity resolution | 62ms | 231ms | OMNI (3.7x) |
| Filing search | 64ms | 281ms | OMNI (4.4x) |
| Section extraction | 64ms | 348ms | OMNI (5.4x) |
| XBRL-to-JSON | 61ms | 392ms | OMNI (6.4x) |
| Operation | OMNI p50 | edgartools p50 | Winner |
|---|
| Entity resolution | 34ms | 471ms | OMNI (13.9x) |
| Filing search | 38ms | 688ms | OMNI (18.1x) |
| Section extraction | 34ms | 3,081ms | OMNI (90.6x) |

edgartools numbers are preliminary pending external methodology review (OMNI-3064). See benchmark-results and compare-edgartools for the full comparison and reproducible methodology. Pricing
| Tier | OMNI | sec-api.io | edgartools |
|---|
| Free | 250 calls/month (renewable) | 100 calls (lifetime) | Unlimited (MIT, truly free) |
| Pay-as-you-go | From $0.01/call | Not offered | N/A |
| Personal | $55/month | $49/month | $0 |
| Business/Team | $239/month | $199/month | $0 |
| Enterprise | Custom | Custom | None (community-supported) |
- OMNI vs sec-api.io: OMNI offers true pay-as-you-go with no monthly minimum. An agent making 200 queries/month pays 4withOMNIvs49 minimum with sec-api.io.
- vs edgartools: edgartools is genuinely free (MIT Python library, calls SEC directly). The tradeoff is client-side parsing, no SLA, no commercial support, Python-only, and a latency/payload profile that’s 13.9-90.6× and 600-1,000× higher than OMNI on the operations above. See compare-edgartools for when each is the right choice.
